Pinpoint Test E : DTC P07F5

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 TRCM receives two voltage inputs from the BJB. The hot in start and run fuse 23 (15A) circuit powers the TRCM micro processor. The hot at all times fuse 83 (20A) circuit powers the motors in the TRCM that are used to move the selector lever cable and the transmission manual valve inside the main control valve body.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    TRCM P07F5:00 Transmission Range Control Module System Voltage Low: No Sub Type Information The TRCM monitors the two voltage inputs for low or no power. When the voltage drops below a calibrated threshold, the TRCM sets the DTC.

    Possible Sources 

    • Connectors damaged or pushed-out terminals, circuitry open, shorted to power or shorted to ground
    • BJB fuse 83 (20A)
    • BJB fuse 23 (15A)
    • TRCM

  2. E1 RETRIEVE AND RECORD ALL DTCS

    • Using the diagnostic scan tool, retrieve all DTCs.

    Is DTC P07F5 present? 

    Yes  GO to  E2
    No  The system is operating correctly at this time. The fault may have been caused by a previous low battery condition.

  3. E2 CHECK THE TRCM (TRANSMISSION RANGE CONTROL MODULE) POWER CIRCUITS FOR VOLTAGE

    • Ignition OFF.

    • Disconnect TRCM C1693.

    • Inspect the connector for damaged or pushed-out terminals.

    • Ignition ON.

    • Measure:

      		 Ground

    Is voltage greater than 11 volts? 

    Yes  GO to  E7
    No  GO to  E3

  4. E3 CHECK THE BJB (BATTERY JUNCTION BOX) FUSE 83 (20A)

    • Ignition OFF.

    • Remove the BJB fuse 83 (20A)

    • CHECK fuse 83 (20A).

    Is the resistance less than 3 ohms? 

    Yes  GO to  E4
    No  GO to  E5

  5. E4 CHECK THE BJB (BATTERY JUNCTION BOX) FUSE 23 (15A)

    • Remove the BJB fuse 23 (15A)

    • CHECK fuse 23 (15A).

    Is the resistance less than 3 ohms? 

    Yes  GO to  E6
    No  GO to  E5

  6. E5 CHECK THE TRCM (TRANSMISSION RANGE CONTROL MODULE) POWER CIRCUITS FOR A SHORT TO GROUND

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1693-6

      		 Ground
      C1693-12
      GFD483791Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  E6
    No  REPAIR the circuit.

  7. E6 CHECK THE TRCM (TRANSMISSION RANGE CONTROL MODULE) POWER CIRCUITS FOR AN OPEN

    • Disconnect BJB C1035A.

    • Disconnect BJB C1035B.

    • Inspect the connectors for damaged or pushed-out terminals.

    Is the resistance less than 3 ohms? 

    Yes  INSTALL a new BJB.
    No  REPAIR the circuit.

  8. E7 CHECK THE TRCM (TRANSMISSION RANGE CONTROL MODULE) GROUND CIRCUITS FOR AN OPEN

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1693-1

      		 Ground
      C1693-2
      GFD483791Courtesy of FORD MOTOR COMPANY
      		 Ground

    Is the resistance less than 3 ohms? 

    Yes  INSTALL a new TRCM. REFER to: Transmission Range Control Module (TRCM) .
    No  REPAIR the circuit.
