Pinpoint Test 4

PINPOINT TEST 4: THE HAZARD LAMPS ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) provides voltage to the indicator flasher relay through circuit (R/W). The indicator flasher relay routes the voltage to the multifunction switch through circuit (W/R). When the hazard switch is engaged, the multifunction switch routes the voltage to all the turn lamps.

Possible Causes
- Fuse
- Circuit (R/W) open
- Circuit (W/R) open, short to ground or voltage
- Indicator flasher relay
- Multifunction switch
- SJB
