C2 & C2 Audible Modules
Many modern vehicles are now fitted with a ECU based indicator function. This means that the old style flasher unit no longer exists in these vehicles. In order for the
driver to be notified of Trailer indicator failure, a C2 module is positioned in the harness at the rear. This will activate a double
flash frequency of the car indicators should a bulb fail on the trailer.

This gives you the total confidence that an indicator bulb failure is monitored in the most applicable way to suit the
vehicle.

Relay replacement - Lamp or Audible
On vehicles equipped with flasher units, the old unit is removed and
replaced with a choice of relay with 2 pins for a remote lamp mounted on the dashboard, or an alternative option of a relay with a built-in audible function. This has been
engineered to sound only when additional load is detected, e.g when a trailer lighting board is fitted. This latter choice is optimum as no drilling of the dashboard is
required.

CANbus modules
Multiplexed CANbus systems are
becoming more and more common in modern motor vehicles. It has also become essential for towbar wiring kits to keep module development in accord with these
systems. Therefore, in many applications, we have a CAN bus module incorporated in our kits which act as a receiver for signals passed by the car. It becomes
no longer necessary for signals to be taken directly from the rear lamp wiring harness ( with certain exceptions e.g the 3rd brake lamp), but rather directly from the CAN
bus data wires. This ensures any safety features associated with towing, operate automatically and as they were intended.

Fog Lamp Cut-off
All our kits have fog lamp cut-off as standard. Either by mechanical or
electrical method.
Mechanical - The fog light feed is broken with either a sprung loaded metal strip or a microswitch ( On 13 pin systems), which are housed inside the socket. The insertion of the plug into the socket forms the break.
|
| |
Electrical – With this method, the contact is broken by the use of a relay which is prepared in the harness
and breaks the circuit when it detects a fog light fitted on the trailer being switched on. The relay is mounted in the vehicle.
Diagnostically Coded - In most modern CAN-bus equipped vehicles the electronic
system is re-coded for towing purposes using specialist diagnostic equipment. The vehicle detects when ever a trailer is plugged in and automatically cuts-off the fog
light. (This will only work if a vehicle specific wiring kit is used).
