No Crank Test: Cherokee

  1. If vehicle is equipped with M/T, go to next step. If vehicle is equipped with A/T, go to step  10.
  2. Turn ignition switch to LOCK position. Ensure vehicle is in Neutral and parking brake is applied. Remove starter relay from Power Distribution Center (PDC). PDC is located in engine compartment. Refer to PDC label for starter relay identification. Connect a jumper wire between starter relay connector terminals C6 and C9. See Fig 1. If engine cranks, go to next step. If engine does not crank, go to step  6.
  3. Using DVOM, check for battery voltage at starter relay connector terminal C6 (Yellow wire). See Fig 1. If battery voltage exists, go to next step. If voltage does not exist, repair open in wiring from starter relay connector to battery. Recheck system.
  4. Depress clutch. Check for battery voltage at starter relay connector terminal C8 (Yellow wire) with ignition switch in START position. See Fig 1. If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit between ignition switch and relay connector. Recheck system.
  5. Using DVOM, measure resistance between starter relay connector terminal C6 (Black/White wire) and ground. If resistance is less than 5 ohms and no problems are found, replace starter relay. Recheck system. See Fig 1. If resistance is 5 ohms or more, repair open circuit.
  6. Check battery cables for voltage drop. See FEED CIRCUIT RESISTANCE TESTS . If no problem is found, go to next step. If excessive resistance is found, repair as necessary. Recheck system.
  7. Ensure starter relay is removed. Disconnect Brown wire from starter solenoid. Using DVOM, measure resistance of Brown wire between starter relay connector terminal C9 and starter solenoid. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Brown wire. Recheck system.
  8. Check for battery voltage at starter relay connector terminal C6 (Yellow wire). See Fig 1. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in wiring between starter relay connector and battery. Recheck system.
  9. Depress clutch. Check for battery voltage at starter relay connector terminal C8 (Yellow wire) with ignition switch in START position. If battery voltage exists, go to next step. See Fig 1. If battery voltage does not exist, repair open circuit between ignition switch and starter relay connector. Recheck system.
  10. Turn ignition switch to ON position. Ensure transmission is in Park. Using scan tool, select INPUTS/OUTPUTS. Check Park/Neutral Position (PNP). If PARK/NEUTRAL is displayed, go to next step. If PARK/NEUTRAL is not displayed, see DTC P1899: P/N SWITCH PERFORMANCE (A/T) under DIAGNOSTIC TESTS in SELF-DIAGNOSTICS - CHEROKEE article in ENGINE PERFORMANCE.
  11. Connect a jumper wire between starter relay connector terminals C6 (Yellow wire) and C9 (Brown wire). See Fig 1. If engine cranks, go to next step. If engine does not crank, go to step  13.
  12. Using DVOM, measure resistance between starter relay connector terminal C6 (Black/White wire) and ground. If resistance is less than 5 ohms, replace starter relay. See Fig 1. If resistance is 5 ohms or more, repair open Black/White wire between starter relay connector and 14-pin splice C107, located at back of engine compartment.
  13. Check battery cables for voltage drop. See FEED CIRCUIT RESISTANCE TESTS . If no problem is found, go to next step. If excessive resistance is found, repair as necessary. Recheck system.
  14. Disconnect Brown wire from starter solenoid. Using DVOM, measure resistance of Brown wire between starter relay connector terminal C9 and starter solenoid. If resistance is less than 5 ohms, go to next step. See Fig 1. If resistance is 5 ohms or more, repair open in Brown wire. Recheck system.
  15. Check for battery voltage at starter relay connector terminal C6 (Yellow wire). See Fig 1. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in wiring between starter relay connector and battery. Recheck system.
  16. Check for battery voltage at starter relay connector terminal C8 (Yellow wire) with ignition switch in START position. See Fig 1. If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit between ignition switch and starter relay connector. Recheck system.
  17. If solenoid clicked when jumper wire was used in step  11, repair mechanical problem preventing starter from cranking engine. If solenoid did not click, replace starter.
