Auto Shutdown Relay

NOTE: For connector identification, see CONNECTOR IDENTIFICATION . For component location, see COMPONENT LOCATIONS . For circuit identification and wiring diagram, see WIRING DIAGRAMS . After each repair procedure has been completed, reconnect all components.
NOTE: For auto shutdown relay circuit testing, perform appropriate diagnostic test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS in SELF-DIAGNOSTICS - GRAND CHEROKEE article.
  1. Turn ignition off. Remove Auto Shutdown (ASD) relay from Power Distribution Center (PDC). PDC is located in engine compartment, near battery. If continuity exists, replace relay. If continuity does not exist, go to next step.
  2. 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.
  3. 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.
