TROUBLE SHOOTING
- Check battery for state of charge.
- Check cable connections at battery and starter motor.
- Ensure transmission is fully engaged in Park or Neutral.
- Check fuse F121 (30-amp) in auxiliary junction box, located underhood.
- Check fuse F22 (20-amp) in battery junction box, located on right side of trunk.
- Check fuse F201 (5-amp) in central junction box, located under right side of instrument panel.
ON-VEHICLE TESTING
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. Before testing starter, ensure transmission is in Park or Neutral. |
| CAUTION | Before testing starter, ensure transmission is in Park or Neutral. |
VOLTAGE DROP TEST
Note. Make all voltmeter connections at component terminal rather than at cable or wire end.
Scheme 2
- Verify battery condition. Battery voltage should be 12 volts or more. Load test battery at approximately one-half cold cranking amperage rating. See load tester manufacturer's instructions. If battery voltage is less than 12 volts or loaded battery voltage is less than 9.6 volts, service battery or charging system as necessary.
- Disconnect inertia fuel shutoff switch to disable fuel system. Connect remote starter switch between starter solenoid terminal "S" (Gray wire) and positive battery post. (Scheme 2)
- Connect positive voltmeter lead to positive battery post, and negative lead to solenoid terminal "M" (solenoid-to-motor connection).
- Engage remote starter switch. Voltmeter should indicate.8 volt or less. If voltmeter indicates more than.8 volt, go to next step. If voltmeter indicates.8 volt or less, go to «STARTER GROUND CIRCUIT TEST»(ref-5072-S04184577762000080300000).
- Move negative voltmeter lead to solenoid terminal "B". Engage remote starter switch. If voltmeter still indicates more than.8 volt at terminal "B", go to next step. If voltmeter indicates less than.8 volt, solenoid connections or contacts are bad. Clean solenoid terminals "B", "S" and "M". Repeat steps 2) through 5). If voltmeter still indicates more than.8 volt at terminal "M" and less than.8 volt at terminal "B", solenoid contacts are bad. Replace starter motor. See «STARTER MOTOR»(ref-5072-S13893396432000080300000) under REMOVAL & INSTALLATION.
- Clean cables and connections at solenoid and battery. If voltmeter still indicates more than.8 volt at terminal "B", replace battery cable. NOTE: To locate excessive voltage drop, move voltmeter negative lead toward battery, and check each connection point. When high voltmeter reading disappears, problem is between last connection point and previous connection point.
STARTER GROUND CIRCUIT TEST
Note. Make all voltmeter connections at component terminal rather than at cable or wire end.
Scheme 3
- Disconnect inertia fuel shutoff switch to disable fuel system. Connect remote starter switch between starter solenoid terminal "S" (Gray wire) and positive battery post. (Scheme 3) Using a digital voltmeter set at lowest voltage scale, connect positive voltmeter lead to starter housing, and negative lead to negative battery post.
- Engage remote starter switch while observing voltmeter. Voltmeter should indicate.5 volt or less. If voltmeter indicates more than.5 volt, clean negative cable connections at battery and chassis. Also clean engine ground cable connections at front cover and engine mount bracket. If voltage drop is still excessive, repair or replace negative battery cable and/or engine ground cable as necessary. Repeat starter circuit test after repair to ensure problem has been corrected. If battery and cables test okay and starter motor still cranks slowly or not at all, replace starter motor. See «STARTER MOTOR»(ref-5072-S13893396432000080300000) under REMOVAL & INSTALLATION.
