Principles of Operation

PRINCIPLES OF OPERATION

Non-Hybrid Vehicles - Automatic Transaxle
When the transaxle is in REVERSE (R), the digital transmission range (TR) sensor provides a ground for the reversing lamps relay coil. When the relay is energized, voltage is supplied to the reversing lamps.

Non-Hybrid Vehicles - Manual transaxle
When the transaxle is in REVERSE (R), the reversing lamp switch provides a ground for the reversing lamps relay coil. When the relay is energized, voltage is supplied to the reversing lamps.

Hybrid Vehicles
For Hybrid vehicles, the powertrain control module (PCM) monitors gear status information. When the transaxle is in REVERSE (R), the PCM provides a ground for the reversing lamps relay coil. When the relay is energized, voltage is supplied to the reversing lamps.
