Auto Idle Stop System Inspection

1. Check under these conditions:

• 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.
• The transmission is in D.
• The A/T gear position indicator is not flashing.
• No indicators are 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, and test-drive under these conditions:

• Drive the vehicle at 25 mph (40 km/h) in D, 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.

3. Repeat step 2 several times, then check the auto idle stop system. If the auto idle stop is system working, the system is OK at this time. If the system does not work, do the auto idle stop system troubleshooting .
