PINPOINT TEST 3: THE TRAILER LAMPS ARE INOPERATIVE - TRAILER PARKING LAMP
Normal Operation
The trailer tow parking lamp relay coil receives voltage through circuit (V/W) when the vehicle parking lamps are illuminated. The trailer tow parking
lamp relay coil is grounded through circuit (B/G). The battery junction box (BJB) fuse 8 (20A) supplies voltage to the trailer tow parking lamp relay
switch side. When the trailer tow parking lamp relay is energized, the voltage is routed to the trailer tow connector through circuit (BR).
