Diagnosis & Testing: Notes

Diagnose ABS using New Generation Star (NGS) scan tool (49-T088-0A0) and Adapter Harness (49-F066-002). See RETRIEVING DIAGNOSTIC TROUBLE CODES  . On all models, test ABS CM using DVOM and adapter harness. See ABS CONTROL MODULE  under COMPONENT TESTS.

If ABS test equipment is unavailable, test each component of ABS. See COMPONENT TESTS  . If all ABS components test okay, replace ABS CM with a known-good module and retest system.
