Parking Brake Warning Chime
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. 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 switch is in ON position, the parking brake is engaged, and the vehicle speed is greater than 5 km/h (3 mph).
The parking brake warning chime stops sounding and resets if the parking brake is released, the ignition switch is not in the ON position, if the vehicle speed is less than 5 km/h (3 mph), or after 90 seconds from the time the chime is activated.
The parking brake warning chime inputs are:
- Ignition switch RUN/START status
- Parking brake switch input to the instrument cluster (IC)
- Vehicle speed data communicated by the PCM to the instrument cluster (IC) through the HS-CAN
