Section 6.Messages and Codes

Fault Codes

Refer to the “Pinout Matrix” located in Theory of Operation section for all voltage and resistance values and component interconnection.

Code Description d.F Code d.F: d.8 + d.4 + d.2 + d.1

Notes/Corrective Action

Connect FlashWare and see if the versions for the Display, TPA, PPA, VM, and Armrest Board are displayed. If the Display is not shown, check connections to the Display. If OK, replace the Display. If the other devices are not shown, check connections to the VM from the Display. Verify power to the devices. If OK, replace the VM. If no devices are shown, check for shorts between the CAN High and CAN Low wires. Measure resistance between the CAN High and CAN Low pins going into the Display. The reading should be approx. 180 ohms. If open or shorted, replace the Display.

E1 Code E1: Incorrect Start Procedure for the Armrest Board or Levers

One of the switches on the Armrest Board or one of the lever control switches is out-of-neutral prior to key ON or the seat switch or battery gate switches are closed.

E2 Code E2: Lift Potentiometer (Lever Control) Out-of-Range

Voltage from the lift pot is outside the expected operating range.

E3 Code E3: Tilt Potentiometer

Out-of-Range

Voltage from the tilt pot is outside the expected operating range.

E4 Code E4: Sideshift Potentiometer

Out-of-Range

Voltage from the sideshift pot is outside the expected operating range.

E5 Code E5: 4th Function Potentiometer Out-of-Range

Voltage from the 4th Function pot is outside the expected operating range.

Check the lever/fingertip controls for binding. Check the seat switch and battery gate switches. Test switches. Check resistance of resistor in static strap standoff; should be 200 to 250k ohm.

Publication 1160093, Issued: 20 May 2013

Check pot for binding. Make sure battery voltage is configured correctly. Learn pot. Test pot voltage. Check resistance of resistor in static strap standoff; should be 200 to 250k ohm. Verify configuration jumpers are in place on PPA. Check for shorts to frame. Set amplifier and VM defaults in FlashWare.

Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.

Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.

Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.

Code Description

E7 Code E7: Armrest Board Warning

The Armrest Board is in the process of downloading default parameters.

E8 Code E8: Armrest Board Internal Fault Failure of the restore default parameter download.

E9 Code E9: Armrest Board Internal Fault

EA Code EA: Hydraulic Control Board or PPA Error

A code is present on both the Hydraulic Control Board and PPA.

Notes/Corrective Action

Cycle the Key switch. Default and Learn via FlashWare. If code does not clear, replace Armrest Board.

Cycle the Key switch. Default and Learn via FlashWare. If code does not clear, replace Armrest Board.

Replace the Armrest Board.

EB Code EB: Armrest Board Internal Fault

Lift-Limit Bypass switch on the Armrest Board is closed.

EC Code EC: Armrest Board Internal Fault

ED Code ED: CAN-Bus Error Detected By Hydraulic Control Board

The Armrest Board is unable to communicate with the Hydraulic Control Board.

EE Code EE: CAN-Bus Error Detected By PPA

The Armrest Board has not received communication from the PPA.

Check for codes from the Hydraulic Control Board and PPA and troubleshoot accordingly. Check CT2 coil from PPA per Pinout Matrix. Check pump motor and temp switch circuits. Check PPA Safety circuit between JFP-5 and 11 (dual traction motor trucks ) or JP12-5 and 11 (single traction motor trucks).

Check fingertip switches for binding. Test voltage of the switch. Replace the Armrest Board.

Replace the Armrest Board.

Check power to HCB and Armrest Board. Check communication wires between all VM, HCB, and Armrest Board for continuity and shorts to frame. If OK, replace the Armrest Board or the HCB.

Check power to PPA, VM, and HCB. Check communication wires between all modules for continuity and shorts to frame. If OK, replace the PPA.
