PINPOINT TEST 3: THE REVERSING LAMPS ARE ON CONTINUOUSLY - 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
- Wiring, terminals or connectors
- Reversing lamps relay
- Rear view mirror
- Parking aid module
- PCM

Diagnostic Procedure
