Starter Relay Circuit Test
NOTE:
Perform solenoid test before testing starter relay circuit.
- Ensure battery is fully charged. Starter relay is located within Power Distribution Center (PDC). Locate and remove starter relay. See Figure .
- Turn ignition on. Using voltmeter, check for battery voltage at starter relay connector terminal No. 30. See Figure . If voltage is not present, repair open in wiring from starter relay connector to battery.
- If voltage is present at starter relay connector terminal No. 30, ensure battery voltage is also present at terminal No. 86 of starter relay connector. Check for voltage with ignition switch in START position and clutch pedal depressed (if equipped with M/T). If voltage is present, circuit is okay. Go to step 6) if equipped with M/T or step 7) if equipped with A/T.
- If voltage is not present at starter relay connector terminal No. 86 and vehicle is equipped with A/T, repair open in wiring from ignition switch to starter relay connector. See Figure . If vehicle is equipped with M/T, go to next step.
- Unplug wiring connector from clutch interlock switch mounted on clutch pedal bracket. Connect jumper wire between interlock switch connector terminals. Recheck for voltage at starter relay connector terminal No. 86 with ignition switch in START position. See Figure . If voltage is present at terminal No. 86 of starter relay, check clutch interlock adjustment. Adjust or replace clutch interlock switch on clutch pedal bracket as needed. If voltage is not present at terminal No. 86 of starter relay, repair wiring between ignition switch and starter relay connector. See Figure .
- If vehicle is equipped with M/T, connect voltmeter negative lead to starter relay connector terminal No. 85 and positive lead to terminal No. 86. Turn ignition switch to START position and depress clutch pedal. If voltmeter reads battery voltage, starter relay connector ground circuit is good. Replace faulty starter relay. If voltmeter reading is not battery voltage, repair ground wire circuit.
- If vehicle is equipped with A/T, connect voltmeter negative lead to starter relay connector terminal No. 85 and positive lead to terminal No. 86. Ensure transmission gear selector is in Park or Neutral position. Ground circuit runs through neutral safety switch on transmission. Turn ignition switch to START position. If voltmeter reads battery voltage, starter relay connector ground circuit is good. Replace faulty starter relay.
- If voltmeter reading is not battery voltage, check transmission neutral safety switch for loose or damaged connections. Repair or replace neutral safety switch as required. If neutral safety switch is okay, repair ground wire circuit.
