The DRBIII(R) Scan Tool must be used to erase a DTC.
The following procedures may be used to diagnose the charging system if:
- the check gauges lamp or battery lamp is illuminated with the engine running
- the voltmeter (if equipped) does not register properly
- an undercharged or overcharged battery condition occurs.
Remember that an undercharged battery is often caused by:
- accessories being left on with the engine not running
- a faulty or improperly adjusted switch that allows a lamp to stay on. Refer to Ignition-Off Draw Test (Refer to ELECTRICAL/BATTERY SYSTEM/BATTERY - STANDARD PROCEDURE)
- loose generator belt.
