Only affects the Scénic II phase 1 and the Scénic II phase 2:
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition
feed).
Proceed as follows:
– Renault card in the card reader (keyless vehicle scenario 1, entry-level, without hands-free and scenario 2, top of
the range, hands-free),
– press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
– connect the diagnostic tool and perform the required operations.
To cut off + after ignition feed, proceed as follows:
– disconnect the diagnostic tool,
– press the Start button twice briefly (less than 3 seconds).
– ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out.
Fault context.
Affects VDiag 08, 0C, 0D and 11.
Explanation of the fault context counters.
The are three different counters:
PR022: Dating counter
PR018: Presence counter
PR019: Frequency counter
Dating counter:The counter starts when the fault appears.
Each time the computer switches on and the fault is stored or present, the
counter increases by 1 up to 255.
Presence counter:As soon as the fault is present, the counter goes to 15. If the fault becomes
stored, each time the computer switches on, the number decreases by 1
(from 15 to 0) and goes back to 15 again if the fault reappears.
Frequency counter:Number of times the present fault appears; it sets to 0 when the fault appears.
It increases each time the fault moves from stored to present.
The maximum value of this counter is 15.

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.

WARNING LIGHT MANAGEMENT
Indications of a level 1 fault:
–Check Parking Brake message on the instrument panel display.
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on.
Indications of a level 2 fault:
–Parking brake defective message on the instrument panel display.
–1-second audible warning (from the instrument panel),
–orange warning light (P in a triangle) on the instrument panel comes on.
–SERVICE warning light comes on,
–Red indicator light (brake pad light) on the instrument panel comes on.
– parking brake control lever indicator light flashes.
Warning occurs:
– when the door is opened and a gear is engaged on an automatic transmission,
– when the vehicle is moving, despite the parking brake being applied,
– when the door is opened, with the engine running and the parking brake released,
– when the door is opened, with the engine stopped and the parking brake released, Note:
When the lever warning light stops flashing, the instrument panel message disappears. If the system has a level 2
fault, whenever the lever is used, the indicator light on the lever starts flashing again and the fault message
reappears.

PRESENT
OR
STOREDVEHICLE MOVEMENT WITH MAXIMUM APPLICATION
1. DEF: The computer has detected vehicle movement when parked (parking brake
applied)
NOTESPriorities when dealing with a number of faults:
First deal with faults DF046 Brake motor/cables connection, DF042 Force sensor,
DF035 Undervoltage, DF041 Slope sensor, DF049 Brake application, DF054
Battery voltage too high and DF055 Battery undervoltage, if they are present or
stored.
If none of these faults is present or stored, the parking brake computer is not normally
the cause.
Conditions for applying the fault finding procedure to a stored fault:
Apply the fault finding procedure even if the fault is stored.
Note:
The fault does not remain present after it has been detected.
Special notes:
– this fault indicates that the electronic parking brake computer detected movement
of the vehicle although the parking brake was applied.
– if this fault is present, with the ignition on, the buzzer on the instrument panel is
activated (when the vehicle is moving with the parking brake applied).
This fault is an operational warning. Check the context in which it appears.
It may appear during:
– an application request, whilst the vehicle is still being driven,
– forced assisted release when starting, when the starting conditions have not
been met,
– parked on a steep slope with slippery surface,
– incorrect use of a roller test bench (MOT test).
Only for Vdiag 08 and 0C:
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction section.
If the fault is stored and PR018 = 0 and PR022 > 25, clear the fault: do not take this
fault into account.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline), initialise the
electronic parking brake computer (see Replacement of components).
Issue several braking and release commands to confirm the repair.
Deal with any other faults.
