Test C: The Steering Wheel Control Illumination Is Inoperative

PINPOINT TEST C: THE STEERING WHEEL CONTROL ILLUMINATION IS INOPERATIVE

C1-C3:

Normal Operation
The smart junction box (SJB) sends a pulse-width modulated (PWM) voltage to the steering wheel controls through circuit 1417 (LG/RD) to the clockspring. The voltage passes through the clockspring to the steering wheel control harness and on to the steering wheel controls. Ground is supplied through the clockspring.

Possible Causes
- circuit 1417 (LG/RD) open
- clockspring
