Auto Shutdown (ASD) Relay
- Remove ASD relay from power distribution center. Power distribution center at driver's side front corner of engine compartment, near the battery. Note terminal identification on ASD relay. See Figure .
- To check ASD relay resistance, use ohmmeter and check resistance between terminals No. 85 and 86 on ASD relay. Replace ASD relay if resistance is not 70-80 ohms.
- To check ASD relay operation, connect ohmmeter between terminals No. 30 and 87A on ASD relay. See Figure . Ohmmeter should indicate continuity between terminals No. 30 and 87A on ASD relay.
- Connect ohmmeter between terminals No. 30 and 87 on ASD relay. See Figure . Ohmmeter should indicate no continuity between terminals No. 30 and 87 on ASD relay.
- Connect 16-gauge jumper wire between negative battery terminal and terminal No. 85 on ASD relay. Connect 16-gauge jumper wire between positive battery terminal and terminal No. 86 on ASD relay.
- Continuity should now exist between terminals No. 30 and 87 on ASD relay. No continuity should now exist between terminals No. 30 and 87A on ASD relay. Disconnect jumper wires. Replace ASD relay if defective.
- If ASD relay or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See TESTS W/CODES article.
