Pinpoint Test R : DTC P0563

WARNING: This page is about a different variant/trim than selected.
  1. Refer to Shift Interlock for schematic and connector information.

    Normal Operation and Fault Conditions 

    The GSM module requires an operating voltage that is between 9 and 16 volts. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the GSM setting a DTC. An overcharging condition in the charging system results in the GSM setting a DTC. This DTC may also set due to battery charging or vehicle jump starting events.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    GSM P0563:00 System Voltage High: No Sub Type Information This DTC sets in continuous memory if the voltage supplied to the GSM module is above 16 volts for more than 5 seconds.

    Possible Sources 

    • Charging system concern
    • GSM

  2. R1 CHECK FOR HIGH VOLTAGE DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES

    • Using a diagnostic scan tool, retrieve all CMDTCs.

    Are any charging system Diagnostic Trouble Codes (DTCs) present in the PCM? 

    Yes  DIAGNOSE the vehicle charging concern. REFER to: Charging System .
    No  GO to  R2

  3. R2 CHECK THE BATTERY VOLTAGE

    • Turn off all interior lights, exterior lights and accessories.

    • NOTE: Do not allow the engine speed to increase above 2, 000 RPM while performing this step or the generator may self-excite and result in default charging system output voltage. If engine speed goes above 2, 000 RPM, turn the engine off and restart the engine before performing this step.

      Start and run the engine at approximately 1, 500 RPM for 3 minutes while monitoring the battery voltage.

    Is the battery voltage between 13 and 15.2 volts? 

    Yes  GO to  R3
    No  DIAGNOSE the overcharging condition. REFER to: Charging System .

  4. R3 RECHECK THE GSM (GEAR SHIFT MODULE) FOR DTC (DIAGNOSTIC TROUBLE CODE) P0563

    NOTE: If a GSM self-test is performed, the driver door must be closed and locked. A false P166B and/or P081F DTC sets if the driver door is opened or unlocked during the self-test.

    • Ignition OFF.

    • Ignition ON.

    • Using a diagnostic scan tool, clear the DTCs.

    • Ignition OFF.

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the self-test.

    Is DTC P0563 still present? 

    Yes  GO to  R4
    No  The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.

  5. R4 VERIFY ALL WIRING CONNECTIONS

    • Ignition OFF.

    • Disconnect and inspect GSM C3532 and related in-line electrical connectors.

    • Using a good light source, inspect all  disconnected electrical connectors for the following:

      • corrosion - install new connector or terminal and clean the module pins
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary
      • spread terminals - install new terminals as necessary

    Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals? 

    Yes  INSTALL a new GSM. REFER to: Gear Shift Module (GSM) .
    No  REPAIR as necessary.
