ELECTRICAL SYSTEM
POSSIBLE CAUSE
A. CONTROLLER WIRING FAULT
B. FAULTY TRACTION CONTROLLER
COMPONENT OPERATIONAL CHECK
NOTE: Always check battery condition and state of charge before performing electrical troubleshooting. A faulty
or low charged battery will cause electrical features to not operate as designed and give incorrect readings while
performing electrical tests.
PROCEDURE OR ACTION:
1. Conduct a visual inspection of all connectors/wiring associated with the fault code.
Are any faults detected/observed?
YES: Repair/replace connector or wiring associated with faults found. Refer to the appropriate Electrical
System YRM .
NO: Proceed to Step 2.
2. Re-key the vehicle.
Is the code still present?
YES: Disconnect battery and discharge the capacitor. Connect battery and re-key the vehicle prior to perform-
ing Step 3.
NO: Problem may be intermittent.
NOTE: The capacitor bank will charge only when the main contactor is closed. If the truck is static, tiller arm up,
no inputs commanded; the capacitor voltage is going to be 0 Vdc and KSI (Key Switch Input) voltage shall read
battery voltage.
3. Connect to PC Service Tool, enable main contactor and view diagnostics for capacitor voltage and battery
voltage.
Is CAP voltage same as battery voltage?
YES: Verify battery state of charge and recheck condition. If actual voltage does not agree with PC service
tool diagnostics, proceed to Cause B.
NO: Proceed to Cause A.
