Troubleshooting Communication Error Codes (5x Series)

If a Code 50, 51, 55, 56, 57, 59, 5A, 5E, 5G, or 5J is intermittently displayed, determine if there is a particular pattern that repeats itself. The following table lists possible causes and actions to perform.

Scenario

Code is displayed while traveling

Code is displayed while lifting

Codes are randomly displayed

Action

Check static straps. Refer to “Component Specific Service/ Torque Chart” on pageA-4.

Check over-the-mast cable.

Refer to Shorts to Frame Test (page5-3). Check static straps. Refer to “Component Specific Service/Torque Chart” on pageA-4. Check wiring harness for loose connections in CAN Bus splices. Unplug and inspect associated CAN Bus jacks and pins.

Code is displayed while steering

Check cables and wiring to the Traction Motor. Cable ties should not be too tight. Make sure cable and wire insulation is not damaged.

If the above checks are performed and the code is still displayed, replace the Tractor Manager.

Troubleshooting Code 51

If Code 51 is displayed during SelfTest:

1.Check for correct jump er installation at the Carriage Manager between JPC22-22 and JPC24-4.

2.Check connections at JPC14-4 and JPC14-11.

Troubleshooting Code 57

Code 57 is displayed when the Display Interface Card is unable to comm unicate with the Tractor Manager. The appearance of this code (much larger scale numbers) differs from any other displayed code. Inputs an d Output tests are not accessible when this code is displayed and a 5Q is registered in the error log.

NOTE: This code is displayed if the K2 relay tips are welded when the key switch is turned OFF.

Diagnosis and Repair

Connect FlashWare to the truck and check TM software version. If a valid software version appears, the test is a success.

Troubleshooting Communication Error Codes (5x Series) 5-22

T/S Bus1 wiring from the TM to the Display Interface Card. Check jumper at JPD5.

Unplug all connectors from CM except JC14 and check voltage again. If 12V is present, T/S the circuit that is pulling it down. If not OK, replace the CM.

Attempt to load a valid software version into the TM. If unable to load software, replace TM. If S/W load was successful, check for shorts to frame, static straps, and repair as necessary.
