Aux Cal Menu

Requirements For Calibration

IMPORTANT: The remote hydraulic controller mustbe calibrated anytime any service work is done onthe remote valves or when the controller is changed.

• Before starting the remote hydraulic calibrationprocedure, check the wir ing harness andcomponents for damage or loose connections.Rep lace o r repa i r any damaged par t asnecessary.

• Before calibrating the remote hydraulic controller,be sure the Standard Instrumentation (INST) andArmrest (ARM) controllers are calibrated.

• The hydraulic oil must be warmed to 49°C (120°F)or higher.

• Engine speed must be set to 1500 RPM or higher.• Disconnect any implements before calibration.

Calibration Process

Before the calibration process starts, the system willperform a pre-calibration check. This check includes:

:• Levers and switches for the available valvesections are in the neutral position.

• When equ ipped wi th MegaFlow, p lug thetransducer into the left diagnostic fitting on theremote manifold.

• There are no faults present.• The feedback signal used for the calibration

indicates less than 100 PSI (689 kPa) and isgreater than 0.25 volts.


55-10

If any of these checks do not pass, the calibration willbe exited with a message displayed of the fault.Selection of the INCR or DECR key will bring themain calibration menu back.

If the checks pass, the present calibration values areset to a default value and the calibration process willbegin.

The sequence of calibration is sequential from valvesection one through section five of the availablesections. The valve order for each section is lowerfirst, then raise. The valve and section that is inprocess of calibration will be displayed.

If Equipped with MegaFlow

For vehicles equipped with the Mega-Flow option, apause is provided to allow field technicians tocalibrate both remote systems with one pressuretransducer.

Once the calibration procedure is in progress for the1st remote section, move the 3rd remote lever out ofneutral. The calibration will pause after the 2ndremote section is calibrated. Move the transducer tothe right side diagnostic fitting. Place the 3rd remotelever back into neutral and select continue from themenu. The calibration process will continue.

The valve is commanded to starting current. Afterthree seconds, the pressure reading is verified that ithas not changed more than 27 PSI (186 kPa) higher.If the feedback signal is above this, calibration will bestopped. If the value is below this pressure check,the pressure reading is stored for the initial value andused for a relative reference for the remainder of thisvalve calibration.

Every 200 mS, the commanded current will beincremented until the feedback signal has becomegreater than 27 PSI (186 kPa) from the initial valuerecorded. The valve is then commanded to zerocurrent and allowed to settle for three seconds. Thefeedback is then checked for a value below 18 PSI(124 kPa) from the initial value. A minimum of onesecond and up to 30 seconds is allowed for thissignal to decay. The valve is then commanded at thecurrent just found minus 16 mA. The current isincremented every three seconds until a change of27 PSI (186 kPa) or greater from the initial value isreached. Again the valve is allowed to settle asabove. If the feedback signal does not decay withinthe time frame allowed, the calibration will exit.

When calibration is completed, the thresholds will besaved and Done will be displayed on the standardinstrumentation display. If calibration is stopped, oneof the following messages will be displayed:

• Enable - lever not in neutral during pre-cal check.• Quit - During calibration, the lever of valve being

calibrated was moved from neutral, INCR, Decror PROG key was pushed.

• PSI - Feedback signal out of range low or highduring pre-cal check.

• Cal Time - Pressure takes to long to drop duringsettling phase of calibration

• Cal Halt - Anytime a fault is associated with thesection is detected.

• Cal Fail - Starting current generates too muchpressure or the commanded current has gonethrough its valid range without finding thethreshold.

NOTE: Disconnect any implement from the remotehydraulic valves before performing the AUX CALprocedure.

NOTE: Before performing the AUX CAL procedure,make sure valve spools are moving freely. With theengine running, cycle each remote hydraulic sectionto the extend and retract detente position.

PASSIVE TERMINATOR BENCH TESTThe Tractor is equipped with two passive terminators. One is located on the engine by the engine controller andthe other is in the cab behind the standard instrumentation controller. The passive terminators are used to stabilizethe data bus system This test can be used in conjunction with data bus fault codes when it is desired to checkpassive terminators. To bench test an passive terminator, do the following:

1. Disconnect the terminator and remove it from thetractor.

2. Use a digital multimeter (CAS1559) for thefollowing checks.

3. Measure the resistance between terminal 2 (canhigh) and 4 (can low). The resistance should beapproximately 150 ohms.

4. Measure the resistance between terminal 1 (canpower) and 3 (can ground). The resistanceshould be approximately 3000 ohms.

5. Next measure the resistance between terminals2 and 1, 2 and 3 and 4 and 1, 4 and 3. After amomentary resistance reading the meter willshow an open circuit, or OL (overload).

6. If the correct resistance readings are notmeasured the terminator must be replaced.

FAULT CODE AUX 1010 Set Extend Limit Switch FailureCause:The Data Bus signaled that the set extend limit switch has failed.The remote hydraulic controller received the signal from the armrest.

Possible failure modes:1. The set extend limit switch failed in the armrest controller (in most cases).

2. Software execution error in the armrest controller (small chance).

Solution:The set extend limit switch is on the secondary control panel of the armrest controller. If the set extend limit switchfails in the armrest controller, the fault code ARM 1099 should exist.

1. Check for fault code ARM 1099 at the armrest controller. If ARM 1099 exists, test the function of the set extendlimit switch.If the service tool is connected to the tractor Data Bus, do the following:Go to the Monitor screen by click the Monitor Icon.Click the CHANGE PARAMETER SELECTIONS Icon.Click the ARMREST AUX REMOTE SET SWITCH - EXTEND and then ADD. You will be able to monitor theSet extend limit switch status on the screen.Turn the switch on and off, and watch the status change.If the status display matches the switch changes, the switch is working OK.If the service tool is not connected to the tractor Data Bus or the status display does not match the switchchanges, inspect the switch.The switch is an integrated part of the second panel of the armrest console. If it is suspected that the switchfailed, replace the panel.

2. If ARM 1099 does not exist or the set extend limit switch is working OK, check the function of the armrestcontroller.

NOTE: See schematic sections 49 and 50 at the rear of this section.


55-16

FAULT CODE AUX 1020 Set Retract Limit Switch FailureCause:The Data Bus signaled that the set retract limit switch has failed.The remote hydraulic controller received the signal from the armrest.

Possible failure modes:1. The set retract limit switch failed in the armrest controller (in most cases).2. Software execution error in the armrest controller (small chance).

Solution:The set retract limit switch is on the secondary control panel of the armrest controller. If the set retract limit switchfails in the armrest controller, the fault code ARM 1099 should exist.

1. Check for fault code ARM 1099 at the armrest controller. If ARM 1099 exists, test the function of the set retractlimit switch.If the service tool is connected to the tractor Data Bus, do the following:Go to the Monitor screen by clicking the Monitor Icon.Click the CHANGE PARAMETER SELECTIONS icon.Click the ARMREST AUX REMOTE SET SWITCH - RETRACT and then ADD. You will be able to monitor theset retract limit switch status on the screen.Turn the switch on and off, and watch the status change.If the status display matches the switch changes, the switch is working OK.If the service tool is not connected to the tractor Data Bus or the status display does not match the switchchanges, inspect the switch.The switch is an integrated part of the second panel of the armrest console. If it is suspected that the switchfailed, replace the panel.

2. If ARM 1099 does not exist or the set retract limit switch is working OK, check the function of the armrestcontroller.


FAULT CODE AUX 1030 Remote Function Control 1 ErrorCause:Remote function control for the 1st remote valve flow has failed or is not available to the remote hydrauliccontroller.

Solution:The appearance of such codes indicates a mismatch between the armrest controller and instrumentation controllerconfigurations.

Make sure all connectors on the remote hydraulic controller, the armrest controller, and the instrumentationcontroller are firmly connected. Recalibrate the armrest controller and the instrumentation controller. If the faultcode is recorded again, check for abnormal controller function.

FAULT CODE AUX 8011 Battery Voltage Less Than 9.8 VoltsCause:Battery voltage is too low.

Possible failure modes:1. Battery voltage lower than 9.8 volts.

2. Alternator regulator malfunction.

3. The controller has a bad connection to power or is not grounded properly.

Solution:Check for battery voltage, alternator regulator output, and the controller connection to power and ground.

1. Check for fault codes PTO 10033, ARM 8011, TRANS 8011, and HITCH 8001. These are all fault codes forbattery voltage low. If most exist, it is more likely that the battery voltage low.

2. Test battery voltage. It should be around 12 - 14 volts.

3. If the battery voltage is OK, check system voltage at cavity 1 and 12 of connector C053.Check for bad connection and improper ground at cavity 2 and 11 of the same connector.Check for shortage to the ground along the power supply to the controller.

4. Test alternator output if the battery voltage would not hold even when the tractor has been running.The voltage should be above 14 volts at C077 - B+.

5. If none of above, check the function of the remote hydraulic controller.


FAULT CODE AUX 8012 Battery Voltage Too HighCause:Battery voltage over 17 volts.

Possible failure modes:1. Alternator regulator malfunction.

2. The battery positive wiring is accidentally connected to external higher voltage source.

FAULT CODE AUX 9009 Controller Memory or Configuration ErrorCause:The drivers in the controller are calibrated to evenly drive the remote hydraulic valves. The checksum for the driveroffsets is stored in the controller memory.

Possible failure modes:1. The checksum for the driver offsets is incorrect in the controller memory.

2. The driver offset values are outside the limits.

Solution:The service tool with special engineering software will be able to change the driver offset values to adjust the flowsfrom each remote hydraulic section. If any offset value is set beyond the limits (+ / - 13), this fault code will berecorded. If this is the case, reset the offset values within the limits.

If no operation has been performed to set the offset values, the problem is most likely due to the checksum failure.It means there is a software or hardware defect. This fault code will automatically sets all offsets to zero. Thecontroller will function normally without these offsets, but the amount or control current from the controller to thevalves may differ than that provided with the offsets. Thus the amount of flow from the sections may differ from theoriginal setting. The only option to cure this problem is to replace the controller.

FAULT CODE AUX 9019 - Controller Memory Error - Loss of Operator Adjustment DataCause:The controller has determined that one or more of the adjustment offsets is a value higher or lower than allowed orhas become corrupt.

Possible failure modes:

1. Controller power interrupted during adjustment.2. Adjustment number has become higher or lower than allowed.3. Controller memory failure.

Solution:

The operator adjustment offsets are positive or negative values entered for the extend and retract in each remotesection in order to adjust the flow curve in that section as desired by the operator.

The operator adjustment offsets are set through the ‘AUX ADJUST’ procedure in the ‘AUX SET MENU’. Ifcontroller power or ground is lost during calibration, controller memory fails or new software is installed with loweroffset limits this fault may occur.

1. Verify that the correct adjustment procedure was followed. Properly exit the adjustment procedure beforeremoving power from the controller.

The modified adjustment value takes effect in the controller when the PROG key is pressed after adjusting thevalue. However, this modified value is not saved to the controller memory until the adjustment procedure isexited. (PROG key is pressed at ‘AUX EXIT’)

2. Make sure the controller has the proper connections to power and ground.

3. Enter the ‘AUX ADJUST’ menu on the Instrumentation controller.

A. View and record the offsets for each section.

B. With the key switch ON, but the tractor not running, determine the minimum and maximum offsetsallowed.Enter the adjustment for a section. Press the INCR or DECR keys as required to return the number tozero. Press the INCR key until the number no longer increases (20 for software revision 2.1.0.0). This isthe maximum allowable offset. Press the DECR key until the number no longer decreases (-20 forsoftware revision 2.1.0.0). This is the minimum allowable offset. Return the offset to its original value.

C. If any of the values recorded in step 3a. are outside of the maximum or minimum values determined in, orstep 3b. adjust the values so that they are inside of the valid range. If offset numbers need to be changedin any section, check the hydraulic performance of the section after doing so to ensure that it functionscorrectly.

D. If all of the recorded values are within range, change one of the offsets to a different value then back to itsoriginal value.

E. Properly exit the adjustment menu by going to the ‘AUX EXIT’ display and pressing PROG. Clear the faultcode. Cycle to key switch. Operate the tractor. If the same fault code occurs again, the Remote HydraulicController has failed. Replace the controller.

FAULT CODE AUX 9029 - Controller Memory Error - Loss of Valve Calibration DataCause:

The controller has determined that one or more of the calibration values has become corrupt.

Possible failure modes:

1. Controller power interrupted during calibration.2. Controller memory failure.

Solution:

The remote hydraulic valve calibration ‘AUX CAL’ is used to find the flow threshold current values for the extendand retract in each remote section. If controller loses power or ground during storage of these values or thecontroller memory becomes corrupt this fault code will occur.

1. Verify that the correct calibration procedure was followed. Properly exit the calibration procedure beforeremoving power from the controller.

2. Make sure that the controller has the proper connections to power and ground.

3. Perform the remote hydraulic valve calibration ‘AUX CAL’ procedure.

The ‘AUX CAL’ procedure requires that the Remote Hydraulic Calibration Tool CAS 2806 be connected to theimplement potentiometer connector (C150M) and the load sensing diagnostic port on the remote valve.

4. Clear the fault code. Cycle the key switch. Operate the tractor. If the same fault code occurs again, the RemoteHydraulic controller has failed. Replace the controller.

Verify system voltage at cavity 1 and 12 of connector C053.There should be 12 DVC at both cavities.If the voltage is lower that 9.8 volts, check the battery voltage.If the battery voltage is OK, check along the controller power supply for shortage.If the battery voltage is low, check for battery problem and the alternator regulator.

2. Check the controller ground at cavity 2 and 11 at the same connector.There should be good connections from the two cavities to the clean ground.Otherwise, check along the harness.

3. Clear the fault codes. Shut down the tractor and start again. If the fault code appears again and the controllerdoes not function properly, replace the remote hydraulic controller.

NOTE: A good indication of low battery voltage is fault code AUX 8011. If AUX 8011 appears with AUX 51011, fixthe battery problem first. If there is no AUX 8011, it is more likely controller problem.


FAULT CODE AUX 51012 Remote Valve Supply Voltage Out Of Range HighCause:Aux remote controller failure - valve supply relay voltage high.

Possible failure modes:1. Control supply voltage being near upper limit of voltage range.2. The controller has bad connection to battery or is improperly grounded.3. Control failure.


1. Verify system voltage at cavity 1 and 12 of connector C053. There should be 12 DVC at both cavities.If the voltage is higher than 15 volts, check the battery and the alternator regulator.

2. Check the controller ground at cavity 2 and 11 at the same connector. There should be good connections fromthe two cavities to the clean ground. Otherwise, check along the harness.

3. Clear the fault codes. Shut down the tractor and start again. If the fault code appears again and the controllerdoes not function properly, replace the remote hydraulic controller.

NOTE: A good indication of high battery voltage is fault code AUX 8012. If AUX 8012 appears with AUX 51012, fixthe battery problem first. If there is no AUX 8012, it is more likely controller problem.

FAULT CODE AUX 51029 Valve Power Supply Relay Contact Out Of Range HighCause:There is an internal relay inside the remote hydraulic controller. This relay supplies voltage to the remote hydraulicvalves when it is energized. If it senses voltage when it is not energized, this fault code will be recorded.

Possible failure modes:1. Controller internal relay stuck closed.

2. Wires from the controller to the valves shorted to power when the relay is not on.

Solution:Make sure there is no external shortage between power supply of the remote hydraulic controller and any of theterminals of the remote valve motors. Check the function of the controller.

1. Check for wire shortage to power.a. Disconnect connector C053 (Gray) and C054 (Black) from the remote hydraulic controller.b. Check the voltage on all the terminals of the remote valve motors (cavity 3, 4, 5, 6, 7, 8, 9, 10 of C053 and allcavities of C054).There should be no voltage on any terminals.If there is voltage (above 1 volt) on any terminal, trace the wire for shortage.c. Pay attention to wire shortage between power supply (cavity 1 and 12 of C053) and any of the terminals.If the resistance between any of them is low, check for wiring damage.

2. If no external shortage, check controller internal relay.The relay will turn on after the power is turned on for two seconds and turn off after the power is turned off.A ’click’ can be heard when listening close to the controller when the relay turns on or off. The ‘click’ can alsobe felt when the controller box is touched with a bare hand.Open the controller cover on the back of the tractor.Listen or feel for the relay ‘click’ when the key is on for more than two seconds and then turned off.If there is click, the relay is working OK.If there is no click, replace the controller.

NOTE: If the problem is intermittent, it may be caused by temperature change on a progressively deterioratingcontroller.


FAULT CODE AUX 51031 Controller Internal FailureCause:Remote valve current enable protection error: valve current enable out of range low.

Possible failure modes:Controller failure.


1. Verify system voltage at cavity 1 and 12 of connector C053.The voltage should be within 9.8 - 14.5 volts. If not, check the battery and the alternator regulator.

2. Check the controller ground at cavity 2 and 11 at the same connector.There should be good connections from the two cavities to the clean ground.

3. Clear the fault codes. Shut down the tractor and start again. If the fault code appears again, replace the remotehydraulic controller.
