Test K: The Turn Signal Lamps Are Inoperative

PINPOINT TEST K: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) sends reference signals to the multifunction switch through circuit CLS20 (BN/BU) (LH turn input) and circuit CLS24 (BN/WH) (RH turn input). When the multifunction switch is switched to the LH or RH TURN positions, the voltage signal is routed to ground. When the SJB detects the multifunction switch in the LH or RH TURN position, the SJB sends voltage to the appropriate turn lamps.

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