Test S: The Reversing Lamps Are On Continuously

PINPOINT TEST S: THE REVERSING LAMPS ARE ON CONTINUOUSLY

S1:

Normal Operation
The smart junction box (SJB) provides voltage to the digital transmission range (TR) sensor, or the reversing lamp switch, through circuit CBP20 (YE/VT). When the transmission is placed in REVERSE, the digital TR sensor, or the reversing lamp switch, routes the voltage to the reversing lamps through circuit CET41 (BN/YE).

Possible Causes
- Circuit CET41 (BN/YE) short to voltage
- Reversing lamp switch
- Digital TR sensor
