Pin Voltage Charts
NOTE:
Unless stated otherwise in testing procedures, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Voltage readings may vary slightly due to battery condition or charging rate.
- ECU circuits are checked at ECU connector under one or more of the following conditions: ignition switch off, ignition on and engine off, or ignition on and engine running.
- To test pin voltage, carefully backprobe terminal at harness side of ECU connector. Test between indicated terminal and body ground. See Fig 1 -Fig 3 . Use wire color to help identify terminal. See WIRING COLOR CODE table.
- If resistance or voltage is not as specified, test and repair or replace circuit or affected component. See Fig 2 and Fig 3 . Retest circuit to verify repair has been made. Unless stated otherwise, perform all tests with ECU harness connected.
