VLM6 Installation & User Guide
1 Introduction
The VLM6 is an electronic module that can be fitted to Swift Group caravans to fix road lighting incompatibility issues
with some tow vehicle and caravan combinations.
The unit is compatible with 2019 model year caravans and 2018 model years caravans fitted with the larger format
C44+ fuse box, which was introduced in October 2017.
2017 and earlier model year caravans should continue to be fitted with the VLM4 unit if required. The VLM6 is not
compatible with these caravans.
2 Overview
The VLM6 is a plug and play replacement for the C44+ road lighting fuse box which is located at the front of the
caravan. The installation process is described below, but in simple terms the C44+ fuse box is removed and replaced
by the VLM6, no extra connections or wires are needed.
The VLM6 has a cooling fan fitted to the unit which operates when the tow car is connected to the caravan and is
used to keep the unit cool during normal operation. It is IMPORTANT that this fan is not blocked or covered by items
placed in the bed box area.
The VLM6 is powered by the vehicle battery supply via the 13-pin connector and cable (pin 9 positive and pin 13
negative) so it is important that the tow vehicle is wired accordingly.
3 Installation
Firstly, ensure the caravan is a 2019 model or a 2018 model with C44+ fuse box (the C44+ is a black rectangular
shaped unit as shown in the photo below, which is significantly larger than the earlier C44 model).
Make sure the car is disconnected from the caravan.
Remove the 4 screws holding the C44+ fuse box in place. Retain these screws as you will be reusing them.

VLM6 Installation & User Guide
Pull the fuse box forward and then unplug all the connectors at the rear. Note that the connectors use retaining clips
to lock them in place, so you will need to squeeze or press the appropriate clips to release the connectors.
Remove the fuse box and retain for possible future use (dealers please pass the unit to the customer).
Unpack the VLM6 and orientate it near to the mounting aperture in the caravan. Plug the connectors (removed
above) into the appropriate sockets on the rear of the VLM6. The connectors are colour coded and different sizes to
prevent them being plugged in incorrectly. Ensure the retaining clips click into place after inserting each connector.
Carefully pass the rear of the VLM6 into the mounting aperture and fix the unit in place with the 4 retaining screws
removed earlier.
4 Testing
After installation the unit should be tested for correct operation as follows:
Connect the 13-pin plug to the socket on the car.
Check that the fan on the VLM6 turns on. If the fan does not operate check the supply on the orange (+) and
white/red (-) at the 4-way red connector.
With the driver’s door shut, car ignition on, operate each light in sequence and confirm that they operate correctly
and no warnings are shown in the vehicle.
Now again with the driver’s door shut, with the engine running, operate each light in sequence and confirm that they
operate correctly and no warnings are shown in the vehicle.
Finally, check a combination of lights at the same time, like an indicator, side lights and pressing of the brake all
together. Confirm that all lights work correctly.
If a fault or problem is shown in the vehicle, view the fuse area on the VLM6 and look of a red LED indicator. There
are 2 red LED’s on the unit, one indicates a fault on the left indicator and the other a fault with the right indicator. If
either LED is illuminated or flashing check the indicator lamp units and associated wiring in the caravan. The
following phot and table shows the LED position and status.
Right Indicator (top LED, nearest to the fuses)
LED2 –off –operation OK
LED2 –steady on –under current / open circuit
LED2 –flashing –over current / short circuit
Left Indicator (bottom LED)
LED1 –off –operation OK
LED1 –steady on –under current / open circuit
LED1 –flashing –over current / short circuit
