ELECTRONIC PARKING BRAKE
Fault finding – System operation
PRESENTATION OF THE PARKING BRAKE:
The electronic parking brake provides the following functions:
– keeps the vehicle stationary when stopped (parking brake).
– 'dynamic' emergency brake (if the main brakes fail).
– automatic braking force adjustment according to the slope (adapted application),
– electronically-assisted parking brake application when the engine is stopped (depending on configuration),
– easy start with electronically-assisted parking brake release (depending on configuration),
– manual application and release by pulling on the lever.
SYSTEM COMPONENTS AND OPERATION:
The system consists of the following components:
●Control lever with brake on indicator light.
– For applying and releasing the parking brake.
●Control unit (computer) housing an electric motor, the brake cable hooks, angle sensor and force sensor.
–The angle sensor controls locking according to the angle of the slope.
–The force sensor checks and corrects the force applied to the brakes.
●Clutch pedal position sensor to help with pulling away.
– Informs the computer of the vehicle's clutch position (the position of the pedal enables the torque necessary for
vehicle movement to be obtained).
●Tw o mechanical cables
– Convey the mechanical force to the rear brakes.
●Emergency control cable (in the central storage compartment on the LAGUNA, VEL SATIS and ESPACE and in
the boot on the SCENIC).
– Enables the rear brakes to be released in the event of the battery or parking brake failing.
●Warning lights and symbol on the instrument panel.
– Indicate application, releasing and any faults on the parking brake.
Note:
The parking brake cable play compensation is performed automatically by the control unit.

MANUAL OPERATION:
– The parking brake is engaged by pulling on the control lever (normal braking immobilises the vehicle).
– Over-application can be obtained by pulling and holding the lever for 5 seconds (maximum application for steep
hills or when the vehicle has reached its maximum permissible all-up weight).
– When the parking brake is applied, the computer super-applies if the force applied to the rear brake callipers is
insufficient (pads cooling) or if the computer detects slight vehicle movement. This detection is limited to
24 hours.
– The parking brake is released when the control lever is applied fully and the release switch is pressed.
ASSISTED OPERATION:
The electronic parking brake enables assisted application and release of the brake:
●Applying the brake: When the engine is switched off, the parking brake is applied when the driver presses the
start button
●Releasing: The brake releases when the drive wheels reach the torque required to move the vehicle
(Note:with automatic transmission, the driver's door must be closed).
Restrictions on assisted brake release in automatic transmissions:
Assisted release is not allowed in the following cases:
– Opening the driver's door followed by engaging a gear (gear lever in position D).
– Engaging a gear (gear lever in position D) followed by opening the driver's door. Note:
When the parking brake is applied, the red light on the instrument panel (brake pads) and indicator light on the
lever are lit.
Below 6 mph (10 km/h) pulling the lever applies the rear brakes. Above 6 mph (10 km/h) pulling the lever
provides dynamic emergency braking without locking the rear wheels (statutory deceleration of 1.5 m/s
2).
The electronic parking brake can only be released when the steering column is unlocked (forced + after ignition
feed, see Introduction).
Note: In this case, the instrument panel displays the message Lever in P or N and the buzzer on the instrument
panel sounds.
Note: In this case, release is authorised for 5 s after the driver's door has been opened (e.g. for a manoeuvre).
After 5 seconds release is prevented.
Note:
Assisted braking and release only occurs if the computer has been configured.
For details on how these configurations function, see Configuration and programming.
