Testing ABS and/or ASR system in vehicle - using test unit connected to system via diagnostic interface enabling complete system testing

摘要

The method of testing an ABS and/or ASR system involves using a test system connected via a diagnosis interface to a controller (10) comprises two microprocessors (10a,10b) of the system to be tested and installed in a motor vehicle. Testing is initiated by the test system and includes the entire vehicle system. The vehicle is mounted for testing on a roller bed with individually driven rollers for the wheels of one axle. A test program involves channel-related checking of sensors and control elements. ADVANTAGE - Enables entire system to be tested as one unit without intermediate cables or connectors.
