Test W: The Reversing Lamps Are On Continuously

PINPOINT TEST W: THE REVERSING LAMPS ARE ON CONTINUOUSLY

W1-W6:

Normal Operation
The transmission control module (TCM) sends gear status information to the PCM over the communication network. When a message is sent over the communication network stating the transmission is in REVERSE (R), the PCM provides ground for the reversing lamps relay coil through circuit CLS28 (BU/WH). Voltage is supplied from the battery junction box (BJB) to the coil and the switched side of the reversing lamps relay. When the reversing lamps relay is energized, voltage is routed to the reversing lamps through circuit CLS10 (GN/BN).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Reversing lamps relay
- Rear view mirror
- PCM
