Operation CHARM: Car repair manuals for everyone.

Parking Brake Reminder

The BCM will provide an audible warning intended to remind the driver that his park brake may be on at the beginning of each drive cycle. The BCM activates the park brake chime only when the voltage signal is low on CKT 1134 and vehicle speed above 3 mph is detected. The chime will operate in conjunction with a flashing park brake indicator for any distance the vehicle is driven.
