Operation CHARM: Car repair manuals for everyone.

Parking Brake Reminder

The radio activates the park brake warning as requested by the IPC. The IPC sends a class 2 message to the radio indicating the chime frequency and duration. The park brake warning sounds and the BRAKE indicator illuminates when the following occur:
^ The park brake is applied (signal circuit is low).
^ The vehicle moves 10 - 50 ft (3 - 15.2 meters).
