Diagnostic trouble code (DTC) information
Condition
Note! This diagnostic trouble code (DTC) applies only to brake systems with dynamic stability and traction control (DSTC).
The pedal pressure sensor is located in the power brake booster and informs the brake control module (BCM) when the brake pedal is pressed. The control module uses the information to disengage active yaw control and active brake assistance if the functions are activated and the driver presses the brake pedal.
Diagnostic trouble code (DTC) BCM-0140 is stored if the control module registers an implausible signal from the pedal pressure sensor.
Substitute value
- Traction control is blocked
- Stability control is blocked
- Active yaw control is blocked
- Brake assistance is blocked.
Hint: For information about abbreviations, see Brake system, abbreviations Brake System, Abbreviations.
Possible source
- Contact resistance or oxidation in the terminals or connections
- Open-circuit in the wiring
