Fault Codes Refer to the “Pinout Matrix” located in Theory of Operation section for all voltage and resistance values and component interconnection. Code
Description
Notes/Corrective Action
8B
Code 8B: TPA Fault The TPA informed the VM that a fault is present.
Check voltage to the TPA. Check for TPA codes and troubleshoot per them. If none are present, replace the TPA.
8C
Code 8C: TPA Communication Error The VM did not receive communication from the TPA.
If code clears by cycling Key switch, the adjustable parameters have been reset to default values and require resetting to customer’s requirements via FlashWare. Check power to TPA. Check the power cables to the traction motors. Check both traction motor encoders, temperature sensors, and connections. Check communication wires between the TPA and VM for continuity and shorts to frame. If code does not clear by cycling key, replace the TPA.
8D
Code 8D: Lift Limit Lift-Limit switch (SW31) is open.
Check for correct configuration via FlashWare. (This code is normal and will occur when beyond limits for option.) Check Lift-Limit/Bypass switch (SW31) and wiring. If OK, replace PPA.
8E
Code 8E: Bottler’s Tilt Limit Bottler’s Tilt limit switch (SW30) is open.
Check for correct configuration via FlashWare. (This code is normal and will occur when beyond limits for option.) Check Bottler’s Tilt limit switch (SW30) and wiring. If OK, replace VM.
8F
Code 8F: Requesting Travel In Both Directions Forward and Reverse switches (directional lever on column) are closed at the same time.
Troubleshoot switches and wiring. If OK, replace TPA.
91
Code 91: Configuration Error The VM has detected a configuration error due to lack of information from the Hydraulic Control Board or Armrest Board during SelfTest.
Check power to the Hydraulic Control Board (HCB). Check communication wires between PPA, HCB, and Armrest Board for continuity and shorts to frame. Make sure COMBI jumpers are correctly installed at Armrest Board. Check software versions via FlashWare. If the HCB and/or Armrest Board are not displayed on the Truck Setup screen, “flash” the truck. Replace HCB or Armrest Board.
