This section contains diagnostic tests for the following body systems: Electronic Vehicle Instrument Cluster (EVIC), Electronic Instrument Cluster (EIC), Mechanical Instrument Cluster (MIC), vehicle theft alarm, headlamp doors, automatic door locks, intermittent wipers, illuminated entry, and courtesy lamps.

In order to perform the tests, you must operate the DRBII to reach the module menu level within the diagnostic testing program. See HELP 1 - Operation of the DRBII for Diagnostic Testing for assistance. At the module menu, you can read DRBII faults and perform diagnostic test functions.
