ANTI-LOCK BRAKES

WORKSHOP TESTING

Any malfunction in the ABS is signaled by the

warning lamp in the instrument cluster, which can

be later on diagnosed at the workshop using a

diagnostic tool. Malfunction code retrieval serves

as the basis for detecting and evaluating defects

and inconsistent performance. Data are analyzed

using special diagnostic tool. Following are some of

the common errors that occur

Electrical circuit problem such as intermittent

contact

Component and sensor failure

Sensor signal that deviates from specified

levels

Unusual response and malfunction in the

actuators

Some of the common test which needs to be done

before drive test. This involves a check for the

following:

Correct functioning of all input and output

signals of the ECU

Correct functioning of wheel speed sensors

Correct functioning of all valves and hydraulic

components
