Backup Lamp: Description and Operation

REVERSING LAMPS

Principles of Operation
When the ignition switch is in the RUN position, the smart junction box (SJB) supplies voltage to the digital transmission range (TR) sensor (automatic transmission) or the reversing lamp switch (manual transmission). When the transmission is placed in REVERSE, voltage is routed to the reversing lamps.
