YES- No wiring fault found, controller at fault, contact Service Engineering.
NO- Determine location and repair fault in associated wire.
6. Check for CANbus Short Circuit(s):
a. Disconnect the Battery cable to truck.
b. At the CANbus diagnostic connector ensure:
• Across Pin A & Pin B = 60 Ohms +/-10%
• Across Pin A & Pin C = >47 kOhms
• Across Pin B & Pin C = >47 kOhms
YES- Controller is suspect and likely damaged, contact Service Engineering.
