Did you know that approx. 85% of your car is controlled by an auto electrical system? If your car won’t start or run, the lights and wipers, or the heater or air conditioner won’t work the cause is most likely electrical.
Modern vehicles use more electronic technology than ever before. The control units of vehicles use fancy names, abbreviated to ECU, BCM, SRS, TDM, ABS etc which can be tricky to understand.
It is no longer easy for owners of new vehicles to perform simple maintenance without good knowledge of the electronic components of the engine. Even changing a battery can cause the control unit to malfunction or to record fault codes which brings on the engine management warning light.
