How To Perform Tests
- DO NOT perform any test unless instructed to do so. Follow each test step in order until fault is found. DO NOT replace any part unless directed to do so. When more than one code is retrieved, start with first code displayed.
- DO NOT measure voltage or resistance at ABS control module unless instructed to do so. DO NOT connect any test light unless specified in testing procedure. All measurements are made by probing rear of connector (wiring harness side). Isolate both ends of circuit and turn ignition off when checking for short or open, unless instructed otherwise.
- After each repair, verify all components are properly reconnected, then clear codes. See CLEARING TROUBLE CODES .
