PINPOINT TEST 1: BOTH REVERSING LAMPS ARE INOPERATIVE - HYBRID
Normal Operation
Voltage is supplied from the battery junction box (BJB) fuse 35 (20A) to the coil side of the reversing lamps relay through circuit (Y/GY). The reversing lamps relay switch side is supplied voltage by the BJB fuse 7 (10A) through circuit (W/R). The reversing lamps relay coil ground is controlled by the PCM through circuit (L/W). When the reversing lamps relay is energized, voltage is routed to the reversing lamps through circuit (G/L). The reversing lamps share a common ground through circuit (B/GY).
Possible Causes
- Fuse
- Wiring, terminals or connectors
- Reversing lamps relay
- PCM
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: The battery ground cable must be disconnected for accurate test results when checking ground circuits for continuity to ground.
