PINPOINT TEST R: THE REVERSING LAMPS ARE ON CONTINUOUSLY

R1-R2:

Normal Operation
With the ignition switch in the RUN position and the transmission is placed in REVERSE, the digital transmission range (TR) sensor routes the voltage to the reversing lamps through circuit 140 (BK/PK) and the electrochromatic mirror (if equipped).

Possible Causes
- Circuit 140 (BK/PK) short to voltage
- Digital TR sensor
