Normal Operation
Switched battery voltage is normally provided to the digital transmission range (TR) sensor through circuit 1087 (OG). When the transmission is placed in REVERSE, the digital TR sensor transfers power to circuit 140 (BK/PK) which provides power to the reversing lamps. Ground is provided to each lamp individually through circuit 1205 (BK).

Possible Causes
- Circuit 140 (BK/PK) open
- Circuit 1087 (OG) open
- Digital TR sensor
