Grand Cherokee

  1. Ensure battery is fully charged. Remove starter relay from Power Distribution Center (PDC). Refer to PDC cover for proper relay location. PDC is located in engine compartment.
  2. Turn ignition switch to ON position. Check for battery voltage at starter relay connector terminal No. 30 (Red wire). See Figure. If voltage does not exist, repair open in wiring between starter relay connector and battery.
  3. Connect a jumper wire between starter relay connector terminals No. 30 (Red wire) and No. 87 (Light Green wire). See Figure. If engine does not crank, go to next step. If engine cranks, check starter relay. See STARTER RELAY TEST  under BENCH TESTING.
  4. Check continuity of Light Green wire between starter relay connector terminal No. 87 and starter solenoid. See Figure. If continuity exists, go to next step. If continuity does not exist, repair open in Light Green wire as necessary and recheck system.
  5. Check for battery voltage at starter relay connector terminal No. 85 (Yellow/Red wire) with ignition switch in START position. If battery voltage exists, go to next step. See Figure. If voltage does not exist, repair Yellow/Red wire between ignition switch and starter relay connector terminal No. 85. If circuit to ignition switch is okay, check ignition switch. See IGNITION SWITCH TEST .
  6. Check for continuity between starter relay connector terminal No. 86 (Brown/Yellow wire) and ground. If continuity exists, circuit is okay. See Figure. If continuity does not exist, check for an open or short to Park/Neutral Position (PNP) switch. See PARK/NEUTRAL POSITION SWITCH . If switch is okay, repair open in Brown/Yellow wire as necessary.
