Electric Park Brake Warning Chime

The electric parking brake warning chime warns the electric parking brake is engaged when the vehicle is in motion. The electric parking brake warning chime sounds if the ignition is in RUN, the electric parking brake is engaged, and the vehicle speed is greater than 5 km/h (3 mph). The electric parking brake warning chime stops sounding and resets if the electric parking brake is released, the ignition is not in RUN, the vehicle speed is less than 5 km/h (3 mph), or after 90 seconds from the time the chime is activated. The electric parking brake warning chime sounds a repetitive 0.5 second chime tone through the front speakers.

The IPC  receives the parking brake chime request from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).

The GWM  receives the parking brake chime request from the ABS  module over the High Speed Controller Area Network 1 (HS1-CAN).

When a chime request is received, the IPC  sends the IPC  chime request message to the ACM  and the audio DSP  to sound the chime.
