On older vehicles without an ECU, the electrical wiring and electronics have to be checked by hand using testing equipment such as ammeters and voltmeters. From an on-screen menu they can select a system, for example the brakes, and then the computer will identify the fault, perhaps a faulty sensor or a loose connection. Newer vehicles have computer-controlled engine management systems where auto electricians can connect a laptop computer or hand-held testing device to the vehicle's Electronic Control Unit (ECU).
Re-testing systems to ensure repairs have been successful which may include road testing the vehicle.Researching faults using manufacturers' circuit diagrams and specification manuals.Using specialised equipment to take readings from the vehicle to identify faults.
For instance, duties of an auto electrician may include: Most modern vehicles rely on a wide range of electrical and electronic systems, controlling most aspects of the vehicle's performance. Auto electricians diagnose and repair electrical faults or replace components in motor vehicles, and fit new electrical and electronic parts and accessories.
