VLM5 Towing Kit
1
Introduction
The VLM5 is an electronic module that is used in many motorhomes to control the rear LED road lighting. The unit
includes monitoring of the motorhome rear direction indicators so that if / when a failure occurs this is shown on the
vehicle dashboard (and by a flashing indicator on the VLM5 unit).
The VLM5 also includes the facility to connect an optional towing harness to provide a 13-pin socket for connection
to a light board, trailer or caravan. When this socket is being used the direction indicator monitoring is extended to
cover the device / vehicle being towed.
To provide this extended indicator monitoring you need to follow the connection process described further below.

Overview
The VLM5 is usually installed in the rear of the motorhome in a dry and damp free area. If you do need to disconnect
or remove the unit, please ensure the Negative IN connection is removed last when disconnecting, and connected
first when reconnecting.

User Operation
The VLM5 unit operates automatically and does not need any special or additional actions. The unit is supplied with
power from the Sargent EC series Power Supply Unit (PSU) and therefore this unit should always be turned on when
using your vehicle.
If your vehicle has been fitted with the optional towing wiring harness please follow the steps below to connect your
light board, trailer or caravan.
1) With the Sargent PSU ON and the vehicle ignition OFF, plug the light board, trailer or caravan into the 13-pin
socket.
2) The vehicle will now detect the trailer and flash each indicator to 'learn' the extra indicators fitted on the light
board, trailer or caravan.
3) You can now start the engine when required and use the vehicle / trailer combination.
4) When you have finished towing, turn the engine / ignition off and unplug your light board, trailer or caravan.
If you have problems with lamp failure indication on the vehicle dashboard, please see the fault-finding section
further below.
