Diagnosis & Testing: Notes

On 1995 Protege, ABS warning light can be used to retrieve ABS Diagnostic Trouble Codes (DTCs) that are in ABS control module memory. See RETRIEVING DIAGNOSTIC TROUBLE CODES  . If a fault is currently present (ABS warning light is on), codes must be retrieved using a voltmeter or Self-Diagnosis Checker (49-H018-9A1) and System Selector (49-B019-9A0). See RETRIEVING DIAGNOSTIC TROUBLE CODES  .

On 1996 models, 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  . On all models, test ABS control module using DVOM. See ABS CONTROL MODULE TEST  under COMPONENT TESTING.

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