Battery Symptom Troubleshooting

Low or Dead Battery

NOTE: A battery might be discharged under these conditions:

- Driving a vehicle 6 miles (10 km) or less per day.
- Leaving a vehicle parked without removing the ignition key from the ignition switch.
- Leaving the vehicle idling for excessive periods of time with the headlights on. This prevents the MICU and the gauge control module from entering the sleep modes, which causes excessive parasitic draw.
- Parking the vehicle with the hood unlatched prevents the security system from arming, which causes excessive parasitic draw.

1. Check the battery Battery Test. Recharge or replace the battery if necessary.
