    Yes  GO to  AT2.
    No  The system is operating correctly at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.

  2. AT2 CHECK FOR HIGH VOLTAGE DTCs SET IN OTHER MODULES

    • Using a diagnostic scan tool, retrieve all CMDTCs.

    Are high voltage DTCs such as B1676, P0563, U3003:17 set in more than one module? 

    Yes  REFER to Battery, Mounting and Cables to diagnose an overcharging condition.
    No  GO to  AT3.

  3. AT3 CHECK THE BATTERY VOLTAGE

    • Turn off all interior lights, 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 Battery, Mounting and Cables to diagnose an overcharging condition.
    No  For the ACM, GO to  AT4.For the APIM, GO to  AT5.For the audio DSP module, GO to  AT6For the FCIM, GO to  AT7For the audio RCU module, GO to  AT8.

  4. AT4 CHECK FOR CORRECT ACM OPERATION

    • Ignition OFF.
    • Disconnect and inspect all the ACM connectors.
    • Repair:
      • Corrosion (clean module pins or install new connectors or terminals)
