Auto Idle Stop System Inspection (M/T)

Auto Idle Stop System Inspection

M/T model

1. Check under these conditions:

- Altitude 2,500 m (8,200 ft) or lower (At higher altitudes, auto idle stop is often prevented because of the lack of vacuum in the brake booster).
- The low temperature indicator does not come on.
- The IMA battery level gauge displays at least half of its scale.
- All electrical items (headlights, blower fan, radiator fan, rear window defogger, A/C, etc.) are off.
- Any indicator does not come on.
- 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 press the clutch pedal fully, and stop the vehicle 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.

NOTE: The clutch pedal must be fully pressed when the vehicle is stopped for auto idle stop to work.

4. Repeat step 3 several times, then check the auto idle stop system.

NOTE: During auto idle stop, the engine restarts when the clutch pedal is fully pressed and the shift lever is moved to 1st gear.
