Auto Idle Stop System Inspection

Auto Idle Stop System Inspection

1. Check under these conditions:

- At 2.500 m (8,200 ft) or less altitude (At higher altitudes, auto idle stop is often prevented because of the lack of vacuum in the brake booster).
- The low temperature indicator is off.
- The IMA battery level indicator displays at least half full.
- Climate control off.
- All electrical items (headlights, blower fan, radiator fan, rear window defogger, A/C, etc.) are off.
- The transmission is in D.
- The D indicator is not flashing.
- No heavy load in the vehicle (A heavy load prevents auto idle stop because the system "thinks" the vehicle is going uphill).
- Drive the vehicle on a flat road or downhill.

2. Start the engine.

3. Test-drive under these conditions:

- Drive the vehicle at 25 mph (40 km/h), then stop it within 5-15 seconds.
- Press and hold the brake pedal until the vehicle stops (Do not pump the brake pedal).
- Keep the brake pedal pressed after the vehicle stops.

4. Repeat step 3 several times.
