Pinpoint Test 1

PINPOINT TEST 1: BOTH HEADLAMPS ARE INOPERATIVE

Normal Operation
The smart junction box (SJB) provides voltage to the multifunction switch and the headlamp switch through circuit (W/R). When the headlamp switch is placed in the HEADLAMPS ON position, the voltage is routed to the multifunction switch through circuit (BR/W).

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

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
