Check controll for the electrical kit – what is it and how does it work?

The term check controll is omnipresent, especially when it comes to the electronics of a car. But what does the term stand for and what does it mean? The surveillance of the lamps and their proper functioning is labelled as check controll system, the system is part of the vehicle’s on-board electronics. It serves as a controlling mechanism of different vehicle’s functions, part of those are the full beam, stop lights and rear fog-lamps. If these lights and lamps fail, the driver is informed due to the systems optical indications. Hence, the indications can also be digital informations of the board computer.

What must be payed attention to concerning vehicles’ check controll?

A vehicle’s electronics are not only complicated but also finely calibrated, therefore, even small interventions can have a huge impact. For vehicle’s which entail check controll the electrical kit must hence be conceptualized in a way that ensures the tap of the lighting functions before the lamp test device takes place.

A different solution is to use an electrical kit with a special trailer control device, where lamp currents are generated for the trailer from the vehicle battery out. Incidentally, such a cable set is also strongly recommended for vehicles with too small cable cross-sections (<0.752). We already pay close attention to this when designing and developing our electrical kits. So you just have to make sure when buying that the electrical kit is suitable for vehicles with check-control.

Electric kits with trailer control unit MVG-type 4112

Our electric kits, which are fitted with a trailer control unit of the MVG-Type 4112, are ideally suited for vehicles with check-control and / or with insufficient cable cross-sections (<0.752). You also benefit from the following product advantages:

• Short-circuit proof outputs of the trailer lighting functions
• Suitable for both LED and incandescent trailers
• Microprocessor controlled
• Monitoring of the charging line / charging active with the engine running and a light function
• Made in Germany
