AA5 CHECK FOR VOLTAGE TO THE PARKING LAMP RELAY USING THE RELAY GROUND PIN
-
Measure the voltage between the trailer tow parking lamp relay pin 5, BJB face side and the trailer tow parking lamp relay pin 2, circuit GD120
(BK/GN), BJB face side.
-
Is the voltage greater than 10 volts?
Yes
REPAIR circuit CAT11 (BN) for an open. TEST the system for normal operation.
No
REPAIR circuit GD120 (BK/GN) for an open. TEST the system for normal operation.

Refer to Wiring Diagram Set 95, Trailer/Camper Adapter for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By
Number
Normal Operation - Trailer Tow Stop/Turn Lamp
The trailer tow LH stop/turn relay coil receives voltage through circuit CLS18 (GY/BN) when the vehicle LH rear stoplamp is illuminated. When the
trailer tow LH stop/turn relay is energized, voltage is routed to the trailer tow connector through circuit CAT06 (YE).
The trailer tow RH stop/turn relay coil receives voltage through circuit CLS19 (VT/OG) when the vehicle RH rear stoplamp is illuminated. When the
trailer tow RH stop/turn relay is energized, voltage is routed to the trailer tow connector through circuit CAT09 (GN).
Trailer Tow Parking
The trailer tow parking lamp relay coil receives voltage through circuit CLS30 (VT/WH) when the vehicle parking lamps are illuminated. When the
trailer tow parking lamp relay is energized, voltage is routed to the trailer tow connector through circuit CAT11 (BN).
