How To Use The Circuit Tests: Notes
- DO NOT
run any test unless codes have been set. Make sure all non-EEC related faults are corrected. DO NOT
replace any part unless directed to do so. When more than 1 service code is received, start with lowest code first.
NOTE:
Procedures in the TESTING
section of this article are not in absolute numerical order. Procedures not related to this engine have been removed to eliminate confusion.
- DO NOT
measure voltage or resistance at ECA or connect any test lamps to it, unless specified. All measurements are made by probing the REAR of the connector. Isolate both ends of a circuit and turn ignition off whenever checking for shorts or continuity, unless specified.
- Disconnect solenoids and switches from harness before measuring continuity, resistance or applying 12 volts. Follow each step in order until fault is found. After any repairs, check all component connections and repeat QUICK TEST
