TRAILER SOCKET
DESCRIPTION
General
The trailer socket is mounted at the rear of the vehicle, and receives inputs from the trailer 
ECU. The trailer ECU is mounted behind the rear fuse box, on the RH side of the luggage 
compartment. The trailer ECU receives inputs from the Light Check Module (LCM), which is 
located at the base of the RH A post.
For more information on the LCM, refer to the  Lighting  section of the System Description 
and Operation Workshop Manual.
OPERATION
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fusible link 5 and fuse 53 of 
the passenger compartment fuse box (C0632) on an R wire. Fusible link 5 (C0588) is 
connected to fuse 4, fuse 6, and fuse 17 of the rear fuse box (C2024) by an R wire. Fuse 4 
and fuse 6 (C2020) supply constant battery feeds to the trailer socket (C0499) on RY and 
RU wires respectively. Fuse 17 (C2022) provides a constant battery feed to the trailer ECU 
(C0380) on an RW wire.
Fuse 53 of the passenger compartment fuse box (C0583) provides a constant battery feed 
to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) on an R wire. When 
the ignition switch is turned to the auxiliary position, current flows across the switch (C0099 
on Td6 vehicles, C0028 on V8 vehicles) to fuse 2 of the passenger compartment fuse box 
(C0585) on a G wire. Fuse 2 (C0587) provides an auxiliary ignition feed to the trailer socket 
(C0499) via the rear fuse box (C2022) on a GY wire.
Light Check Module (LCM)
The LCM provides signal inputs to the trailer ECU as follows:
Rear Fog Lamp
The rear fog lamp function of the trailer ECU is controlled via a bi-directional data line 
between the LCM (C2040) and the trailer ECU (C0380) on a UNY wire. When the trailer ECU 
receives a rear fog lamp signal, it provides a feed to the trailer socket (C0499) on a YR wire.
Reverse Lamp
The reverse lamp function of the trailer ECU is controlled via a bi-directional data line 
between the LCM (C2040) and the trailer ECU (C0380) on a UNY wire. When the trailer ECU 
receives a reverse lamp signal, it provides a feed to the trailer socket (C0499) on a YU wire.

RH Tail Lamp
When the LCM (C0937) detects that side or headlamps have been selected, it provides a 
feed to the trailer ECU (C0380) on an SP wire. The trailer ECU (C0380) will now provide a 
feed to the trailer socket (C0499) on an SR wire.
LH Tail Lamp
When the LCM (C2040) detects that side or headlamps have been selected, it provides a 
feed to the trailer ECU (C0380) on an SW wire. The trailer ECU (C0380) will now provide a 
feed to the trailer socket (C0499) on an SB wire.
RH Direction Indicator Lamp
When the LCM (C2039) detects that a right turn has been selected, it provides a feed to the 
trailer ECU (C0380) on a UN wire. The trailer ECU (C0380) will now provide a feed to the 
trailer socket (C0499) on a UY wire.
LH Direction Indicator Lamp
When the LCM (C0937) detects that a left turn has been selected, it provides a feed to the 
trailer ECU (C0380) on a UG wire. The trailer ECU (C0380) will now provide a feed to the 
trailer socket (C0499) on a UR wire.
Brake Lamps
When the LCM (C0937) detects that the brake pedal has been pressed, it provides a feed 
to the trailer ECU (C0380) on a BU wire. The trailer ECU (C0380) will now provide a feed to 
the trailer socket (C0499) on a BW wire.
