and is gradually reduced as the calculated battery The ambient temperature sensor is used to control the battery voltage based upon ambient temperature DIAGNOSIS AND TESTING - ON-BOARD The Powertrain Control Module (PCM) monitors critical input and output circuits of the charging sys- If the OBD system senses that a monitored circuit is bad, it will put a DTC into electronic memory. The DIAGNOSTIC TROUBLE CODES A DTC description can be read using the DRBIII t scan tool. Refer to the appropriate Powertrain Diag- A DTC does not identify which component in a cir- cuit is bad. Thus, a DTC should be treated as a ERASING DIAGNOSTIC TROUBLE CODES The DRBIII t 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 illumi- nated with the engine running • the voltmeter (if equipped) does not register properly • an undercharged or overcharged battery condi- tion 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.
