Pinpoint Test 2

PINPOINT TEST 2: THE LOW BEAMS ARE INOPERATIVE

Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the multifunction switch routes voltage to the smart junction box (SJB) through circuit (L/W). The SJB then routes voltage to the LH and RH low beams.

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