Starter Relay Circuit Test

NOTE: Perform SOLENOID CIRCUIT TEST under ON-VEHICLE TESTING before testing starter relay circuit.
  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. Connect a jumper wire between starter relay connector terminals No. 30 and 87. See Figure. If engine does not crank, go to SOLENOID TEST. If engine cranks, go to next step.
  3. Turn ignition on. Check for battery voltage at starter relay connector terminal No. 30. If voltage is not present, repair open in wiring from starter relay connector to battery.
  4. If voltage is present at starter relay connector terminal No. 30, ensure battery voltage is also present at starter relay connector terminal No. 86. Check for voltage with ignition switch in START position. If voltage is not present, go to next step. If voltage is present, circuit is okay. Go to step 6).
  5. If voltage is not present at starter relay connector terminal No. 86, repair open or short in wiring from ignition switch to starter relay connector. If circuit to ignition switch is okay, check ignition switch. See IGNITION SWITCH TEST under ON-VEHICLE TESTING.
  6. Check for continuity to ground at starter relay connector terminal No. 85. If continuity exists, circuit is okay. If continuity does not exist, go to next step.
  7. If vehicle is equipped with an A/T, check for an open or short to neutral safety switch. See NEUTRAL SAFETY SWITCH under ON-VEHICLE TESTING. If vehicle is equipped with a M/T, repair circuit to ground as required.
