This relay is an essential piece of kit on modern multiplex and Canbus equipped cars to prevent damage to lamp control units & ECU’s
How the TEB7AS works
Modern cars have very sophisticated bulb failure and lamp control systems that constantly monitor the current consumption in individual wires – if you connect tow bar wiring straight on to the loom the computers can shut down, put on warning lamps or in some cases burn out!!
The TEB7AS relay draws only a tiny amount of power from the loom to trigger the internal relay banks – the main output power to the tow bar socket is provided from the 12-volt permanent relay power – this prevents the car from detecting the presence of the tow bar electrics and also protects the cars circuits as any short or problem with the trailer electrics will blow the fuse for the relay – not an expensive ECU!
