Parking Brake Warning Chime
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The parking brake warning chime warns that the parking brake is engaged when the vehicle is in motion. The parking brake warning chime sounds if the ignition is in ON, the parking brake is engaged, and the vehicle speed is greater than 4.8 km/h (3 mph).
The parking brake warning chime stops sounding and resets if the parking brake is released, the ignition is not in the ON state, if the vehicle speed is less than 4.8 km/h (3 mph), or after 90 seconds from the time the chime is activated.
The parking brake warning chime inputs are:
- Ignition state
- Parking brake switch status to the BCM
- Vehicle speed data communicated by the PCM to the BCM through the HS-CAN
- Parking brake warning chime request communicated by the BCM to the IPC through the HS-CAN
