How to Perform Trouble Diagnosis For Quick & Accurate Repair

Diagnosis:

The Anti-Lock Brake System (ABS) system has an electronic control unit to control major functions. The control unit accepts input signals from sensors and instantly drives the actuators. It is essential that both kinds of signals are proper and stable. It is also important to check for conventional problems such as air leaks in booster lines, lack of brake fluid, or other problems with the brake system.

It is much more difficult to diagnose a problem that occurs intermittently rather than continuously. Most intermittent problems are caused by poor electric connections or faulty wiring. In this case, careful checking of suspicious circuits may help prevent the replacement of good parts.

A visual check may not find the cause of the problems, so a road test should be performed too.

Before performing actual checks, take a few minutes to ensure which symptoms are present and under what conditions they occur. Start your diagnosis by looking for conventional problems first. This is one of the best ways to troubleshoot brake problems on an ABS controlled vehicle.
