Test J: The Turn Signal Lamps Are Inoperative

PINPOINT TEST J: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) sends a voltage reference signal to the multifunction switch through circuit 1393 (LB/RD) (LH turn signal) and circuit 1392 (LG/OG) (RH turn signal). When the multifunction switch is placed in the LH or RH TURN position, the signal is routed through circuit 1396 (VT/WH) to an internal ground within the SJB.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multifunction switch
- SJB
