PINPOINT TEST F: THE CONTROL ILLUMINATION DOES NOT DIM

F1-F2:

F3-F4:

F5-F6:

Normal Operation
The smart junction box (SJB) monitors the input from the instrument panel dimmer switch by sending a voltage reference signal through circuit 1403 (BK/WH) to the instrument panel dimmer switch. The return signal is sent through circuit 1036 (BN/WH) back to the SJB.

Possible Causes
- circuit 1036 (BN/WH) open, short to ground, or short to voltage
- circuit 1403 (BK/WH) open, short to ground, or short to voltage
- instrument panel dimmer switch
- SJB
