Auto Shutdown Relay
NOTE:
For auto shutdown relay circuit testing, see DTC P1388: AUTO SHUTDOWN RELAY CONTROL CIRCUIT under DIAGNOSTIC TESTS in appropriate SELF-DIAGNOSTICS article.
- Turn ignition off. Remove Auto Shutdown (ASD) relay from Power Distribution Center (PDC). PDC is located in engine compartment, near battery. See Figure , Figure or Figure . Using an ohmmeter, check for continuity between ASD relay terminals No. 30 and 87. See Figure or Fig 1 . If continuity exists, replace relay. If continuity does not exist, go to next step.
- Measure resistance between ASD relay terminals No. 85 and 86. If resistance is not 50-80 ohms, replace ASD relay. If resistance is 50-80 ohms, go to next step.
- Using jumper wires, apply positive battery voltage to relay terminal No. 86 and ground relay terminal No. 85. Check for continuity between relay terminals No. 30 and 87. Continuity should exist. If continuity does not exist, replace ASD relay.
