    Are high voltage DTCs (e.g. B1317, B1676, P0563, U3003:17) set in more than one module? 

    Yes  REFER to Charging System , Symptom Chart: Charging System to diagnose an overcharging condition.
    No  GO to  AE2.

  2. AE2 CHECK THE BATTERY VOLTAGE

    • Turn off all interior/exterior lights and accessories.
    • Start and run the engine at approximately 2, 000 RPM for 3 minutes while monitoring the battery voltage.

    Does the battery voltage rise to 15.5 volts or higher? 

    Yes  REFER to Charging System , Symptom Chart: Charging System to diagnose an overcharging condition.
    No  GO to  AE3.

  3. AE3 RECHECK FOR DTCs U3003:17

    • Turn the engine off.
