Electronic Handbrake Control Module Description

Vehicles with the electric handbrake have a switch in the centre console, which takes the place of the manual handbrake system, the foot pedal and release handle. In case of insufficient electrical power, the electric handbrake cannot be applied or released.

The parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The handbrake control module also contains the logic for applying and releasing the handbrake when commanded by the handbrake control switch. When the parking brake control module receives a signal from the switch the internal circuit board temperature is checked to verify it is within operating range before the control module performs the requested operation.

The electric handbrake can be applied any time the vehicle is stopped or in motion. The electric parking brake is applied by momentarily lifting up on the park brake control switch. The red park brake light will momentarily flash while the parking brake is being applied. Once fully applied, the red park brake light will turn on. If the electric parking brake is applied while the vehicle is in motion, a chime will sound, and the message "Release Park Brake Switch" will be displayed.

If the red park brake light is flashing, the electric parking brake is only partially applied or released, or there is a problem with the electric parking brake. The message "Service Park Brake" will be displayed.

To release the electric parking brake, turn the ignition switch to the ON or RUN position, apply and hold the brake pedal, and push down momentarily on the park brake control switch. When the electric parking brake is released the red park brake light turns off.

The electric handbrake can be used to prevent roll back for vehicles with a manual gearbox taking off on a hill. In a situation where no roll back is desired, an applied electric handbrake will allow both feet to be used for the clutch and accelerator pedals in preparation for starting the vehicle moving in the intended direction. In this situation, perform the normal clutch and accelerator actions required to begin moving the vehicle. There is no need to push the switch to release the electric handbrake. To disable this feature lift and hold the park brake control switch while the vehicle is in motion, this will keep the electric parking brake applied.
