PARKING BRAKE RELEASE WARNING CHIME: System Description: Description

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control unit) via CAN communication line.
The combination meter judges whether the parking brake is released using the parking brake switch signal from the parking brake switch, and sounds the warning buzzer if necessary.
