O2 Continued:

Normal Operation - Trailer Tow Turn/Stoplamps
When the trailer tow turn lamp relay is energized, voltage is routed to the trailer tow connector through circuit 52 (YE) (LH stop/turn lamp) and/or 64 (DG) (RH stop/turn lamp).

Normal Operation - Trailer Tow Parking Lamps
When the trailer tow parking lamp relay is energized, voltage is routed to the trailer tow connector through circuit 962 (BN/WH).

Normal Operation - Trailer Tow Reversing Lamps
When the trailer tow reversing lamp relay is energized, voltage is routed to the trailer tow connector through circuit 963 (BK/LG).

Possible Causes
- Circuit 52 (YE) short to voltage
- Circuit 64 (DG) short to voltage
- Circuit 962 (BN/WH) short to voltage
- Circuit 963 (BK/LG) short to voltage
- Trailer tow relay
