Diagnosis & Testing: Notes

ABS DTCs are retrieved using New Generation Star (NGS) Tool (49-T088-0A0 ) and NGS Self-Test Adapter (49-T088-003 ). See RETRIEVING DIAGNOSTIC TROUBLE CODES  . Test ABS CM using a DVOM. See ABS CONTROL MODULE  under COMPONENT TESTS.

If ABS test equipment is unavailable, ensure wiring harness and connectors are okay. Test each ABS component. See COMPONENT TESTS  . If wiring harness, connectors and all ABS components are okay, replace ABS CM with a known-good module and retest system.
