Electronic Hand brake Control Module Description

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

The hand brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The hand brake control module also contains the logic for applying and releasing the hand brake when commanded by the hand brake control switch. When the hand 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 hand brake can be applied any time the vehicle is stopped or in motion. The electric hand brake is applied by momentarily lifting up on the hand brake control switch. The red hand brake light will momentarily flash while the hand brake is being applied. Once fully applied, the red hand brake light will turn on. If the electric hand brake is applied while the vehicle is in motion, a chime will sound, and the message "Release Hand brake Switch" will be displayed.

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

To release the electric hand brake, with power mode is Vehicle ON, or Engine Running, apply and hold the brake pedal, and push down momentarily on the hand brake control switch. When the electric hand brake is released the red hand brake light turns off.

The electric hand brake 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 hand brake 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 hand brake. To disable this feature lift and hold the hand brake control switch while the vehicle is in motion, this will keep the electric hand brake applied.
