  1. J1 RETRIEVE ALL CM DTCS IN ALL MODULES

    NOTE: DTC P0562:00 or P0563:00 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on.

    • Ignition ON.

    • Enter the following diagnostic mode: Retrieve All CM DTCs.

    Is DTC P0562:00 or P0563:00 present in one or more modules and P0563, P0620, P0625, P0626 or P065B present in the PCM?

    Yes  GO to  J3
    No  CHARGE or INSTALL a new battery. REFER to: Battery .

  3. J3 CHECK THE CHARGING SYSTEM VOLTAGE

    • NOTE: Do not allow the engine RPM 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 RPM has gone above 2, 000 RPM, shut the vehicle OFF and restart the engine before performing this step.

      Start the engine

    • Measure the voltage of the battery:

      • For DTC P0562:00, turn on headlights and HVAC fan on high and run engine at 1, 500 RPM for a minimum of 2 minutes.

      • For DTC P0563:00, turn off all accessories and run the engine at 1, 500 RPM for a minimum of 2 minutes.

    Is the battery voltage between 13-15.2 volts? 

    Yes  For DTC P0562:00, GO to  J4 For DTC P0563:00, GO to  J6
    No  To DIAGNOSE the charging system, CLEAR all CM DTCs.

  4. J4 CHECK VOLTAGE AND GROUND TO THE TCCM

    • Ignition OFF.

    • Disconnect TCCM C2371B.

    • Ignition ON.

    • Measure:

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2371B-7

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  REPAIR the circuit. CLEAR all CM DTCs.

  6. J6 CHECK FOR CORRECT TCCM OPERATION

    • Ignition OFF.

    • Disconnect and inspect all TCCM connectors.

    • Check for the following:

      • corrosion (install new connector or terminals - clean module pins)

      • damaged or bent pins - install new terminals/pins

      • pushed-out pins - install new pins as necessary

    • Connect all TCCM connectors. Make sure they seat and latch correctly.

    • Operate the system and verify the concern is still present.

    Is the concern still present? 

    Yes  INSTALL a new TCCM. REFER to: Transfer Case Control Module (TCCM) .
    No  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of the connector or pin issues.
