Symptom Chart: External Controls

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).

In most circumstances, the PCM sets a DTC to help guide with diagnostics. Refer to the DTC Chart before using the Symptom Chart. The Symptom column lists the vehicle condition. The Possible Sources column lists a detailed vehicle condition. The Action column lists the action to be performed to determine the cause of the condition. Each action lists the components that can cause the condition and the individual components in that system. The components are listed in order of disassembly. Use the list of components and the required action to focus on disassembly inspections for the root cause of the concern.

Pinpoint Tests

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).


Refer to Wiring Diagrams Cell 37 for schematic and connector information.

Brake Shift Interlock Actuator (BSIA) B2572

Normal Operation and Fault Conditions

The CJB provides power to the Brake Shift Interlock Actuator (BSIA) solenoid. When the CJB receives a brake pedal applied input, voltage is applied to the brake shift interlock solenoid. When the solenoid is energized, the plunger is pulled inward allowing the selector lever to move from the P position.



  DTC Fault Trigger Conditions


DTC Description Fault Trigger Conditions
B2572 Brake Shift Interlock Output Circuit Failure The associated circuitry connected to the CJB or fuse, or the CJB itself may have an issue causing a brake shift interlock concern.


Possible Sources


PINPOINT TEST A : BRAKE SHIFT INTERLOCK ACTUATOR (BSIA) B2572

  • Apply the brake pedal and view the brake lights.

Do the brake lights illuminate?

Yes GO to A2
No
REFER to: Stoplamps (417-01 Exterior Lighting, Diagnosis and Testing).


A2   TEST THE TCM (TRANSMISSION CONTROL MODULE) INTERNAL GROUND CIRCUIT OPERATION
  • Using the diagnostic scan tool, monitor the SHFTLCK_ALLW and BOO_TCM PIDS, while pressing the brake pedal off and on.

Does the SHFTLCK_ALLW and BOO_TCM status change?

Yes GO to A3

SelectShift™

Normal Operation and Fault Conditions

The SelectShift™ switch is a toggle switch integral to the selector lever knob. When the selector lever is placed in the S position, the upshift/downshift feature becomes activated. If a new switch is required install a new selector lever knob.



  DTC Fault Trigger Conditions


DTC Description Fault Trigger Conditions
