Pinpoint Test A: P0562: 00 And P0563: 00

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to Wiring Diagrams Two Wheel Drive/Four Wheel Drive Systems for schematic and connector information.

    Normal Operation and Fault Conditions 

    If the TCCM observes an overpower or underpower voltage condition, a DTC is set and all TCCM outputs are turned off (IWE engaged).

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    TCCM P0562: 00 System Voltage Low: No Sub Type Information This DTC sets when the TCCM detects battery voltage less than 9 volts for 5 seconds or more at the TCCM.
    TCCM P0563: 00 System Voltage High: No Sub Type Information This DTC sets when the TCCM detects battery voltage greater than 16 volts for 5 seconds or more at the TCCM

    Possible Sources 

    • Fuse
    • Charging System
    • Wiring, terminals or connectors
    • Connectors
    • TCCM

  2. A1 RETRIEVE ALL CMDTC (CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODE) 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 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 CMDTCs.

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

    Yes  For diagnosis of the battery and charging system, REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (272kW/370PS) . REFER to: Charging System - 3.0L Power Stroke Diesel . REFER to: Charging System - 3.0L Power Stroke Diesel . .
    No  GO to  A2

  3. A2 CHECK BATTERY CONDITION

    • Ignition OFF.

    • Carry out the Battery Condition Test, REFER to: Battery . .

    Does the battery pass the condition test? 

    Yes  GO to  A3
    No  CHARGE or INSTALL a new battery, REFER to: Battery . .

  4. A3 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 exceeded 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 the headlights and the HVAC fan on high and run the 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  A4 For DTC P0563: 00, GO to  A6
    No  To diagnose the charging system, REFER to: Charging System - 2.7L EcoBoost (238kW/324PS)/3.5L EcoBoost (272kW/370PS) . REFER to: Charging System - 3.0L Power Stroke Diesel . REFER to: Charging System - 3.3L Duratec-V6/5.0L 32V Ti-VCT .

  5. A4 CHECK GROUND TO THE TCCM (TRANSFER CASE CONTROL MODULE)

    • Ignition OFF.

    • Disconnect TCCM C2371B.

    • Ignition ON.

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C2371B-7
      GFD551830Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage between 11 and 14 volts? 

    Yes  GO to  A6
    No  GO to  A5

  6. A5 CHECK VOLTAGE SUPPLY TO THE TCCM (TRANSFER CASE CONTROL MODULE)

    • Positive Lead Measurement / Action Negative Lead
      C2371B-7
      GFD551649Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the voltage between 11 and 14 volts? 

    Yes  REPAIR the ground circuit. CLEAR all CMDTCs.
    No  VERIFY BJB fuse 82 (25A) and 64 (25A) are OK, REPAIR the open circuit or short to power. If not OK, REFER to the OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION to identify possible causes of the circuit short. CLEAR all CMDTCs.

  7. A6 CHECK FOR CORRECT TCCM (TRANSFER CASE CONTROL MODULE) 4WD (FOUR-WHEEL DRIVE) 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 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.
