Test K: The Turn Signal Lamps Are Inoperative

PINPOINT TESTS PINPOINT TEST K: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Normal Operation
The SJB sends reference signals to the multifunction switch through circuits CLS39 (VT/WH) (LH turn input) and CLS41 (GY/YE) (RH turn input). When the multifunction switch is placed in the LH or RH TURN positions, the voltage signal is routed to ground through circuit GD111 (BK/BU). When the SJB detects the multifunction switch in the LH or RH TURN position, the SJB provides on/off voltage to the appropriate turn lamps.

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