How To Use The Circuit Tests: Notes
- DO NOT run any test unless codes have been set during Quick Test. Make sure all non-EEC related faults are corrected. DO NOT replace any part unless directed to do so. When more than one service code is received, start with the fires code displayed.
- 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 key 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 test step in order until fault is found. After each repair, check all component connections and repeat circuit test.
