PINPOINT TEST S: THE HAZARD LAMPS ARE ALWAYS ON


Test S1:






Test S2-S3:






Normal Operation
The instrument cluster sends out a voltage reference signal through circuit 8-LG43 (WH/VT) to the multifunction switch. The return signal is carried through circuit 9-LG43 (BN/WH) (shared with the high beam circuit) back to the instrument cluster. When the hazard switch is engaged, the voltage signal sent by the instrument cluster passes directly through the multifunction switch and returns to the instrument cluster.

Possible Causes
- circuit 8-LG43 (WH/VT) short to ground
- multifunction switch
- instrument cluster
