Test T: The Reversing Lamps Are On Continuously
PINPOINT TEST T: THE REVERSING LAMPS ARE ON CONTINUOUSLYNormal Operation
When the ignition switch is in the RUN position, voltage is provided to the digital transmission range (TR) sensor from the central junction box (CJB) through circuit 1789 (VT/WH). When the transmission is placed in REVERSE, the digital TR sensor routes voltage to the reversing lamps through circuit 140 (BK/PK).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Interior rear view mirror
- Parking aid module (PAM)
