Pinpoint Test B : The Adjustable Pedals Are Inoperative Or Do Not Operate Correctly - Using The Adjustable Pedals Control Switch: Notes

Diagnostic Overview

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.

Refer to Adjustable Pedals , for schematic and connector information.

Normal Operation and Fault Conditions

The SCCM receives fused battery voltage from the BCM.

Pressing the adjustable pedals control switch causes the SCCM to send current along one circuit to the adjustable pedal motor. The current returns to the SCCM along another circuit and is grounded through the SCCM, this moves the pedals in the desired direction. Pressing the adjustable pedals control switch in the opposite direction reverses the current flow through the circuits and moves the pedals in the opposite direction.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B137D:18	Pedal Adjustment Motor: Circuit Current Below Threshold	Sets when the SCCM detects current flow to the adjustable pedal motor below a preset limit. The SCCM checks for this fault during the on-demand self test.
B137D:19	Pedal Adjustment Motor: Circuit Current Above Threshold	Sets when the SCCM detects current flow to the adjustable pedal motor above a preset limit. The SCCM continually checks for this fault during normal operation when the ignition is ON and during the on-demand self test.
B137D:71	Pedal Adjustment Motor: Actuator Stuck	Sets when the SCCM detects current flow to the adjustable pedal motor is within a specific range but above a preset limit. The SCCM checks for this fault during the on-demand self test.

Possible Causes

Fuse
Wiring, terminals or connectors
Foreign material
Adjustable pedal switch
Adjustable pedal motor and cable assembly
Adjustable brake pedal assembly
SCCM

Visual Inspection and Diagnostic Pre-checks

Inspect BCM fuses 23 (15A) and 24 (15A).
