Brake Pedal Switch Circuit Failure
The anti-lock brake system (ABS) module receives brake pedal switch status from the powertrain control module (PCM) over the high speed communication area network (HS-CAN) bus. If there is a failure in the switch or the HS-CAN bus diagnostic trouble code (DTC) C1446 will be set. A low fluid level condition in the master cylinder or a failure of the brake fluid level switch will also cause DTC C1446 to set.
Possible Causes
- Circuit open
- Low brake fluid
- Brake fluid level switch
- Brake pedal position switch
- ABS module
