Pinpoint Test 3: One High Beam Headlamp Is Inoperative
PINPOINT TEST 3: ONE HIGH BEAM HEADLAMP IS INOPERATIVE
Normal Operation
When the smart junction box (SJB) detects the headlight switch in the HEADLAMPS ON position and the multifunction switch in the HIGH BEAM position, the SJB energizes an internal relay. When the relay is energized, voltage is routed through circuit (Y/V) to the high beams. Ground for the high beams is shared with the low beams.
Possible Causes
- Wiring, terminals or connectors
Diagnostic Procedure
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE: Make sure the headlamp bulb is good before continuing diagnostics.
