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.

ALP2 Will not release
NOTESOnly consult this customer complaint after a full check using the diagnostic tool
(no present or stored faults).
The main causes of the brake not releasing are:
– Driver's door incorrectly closed (on vehicles with an automatic transmission).
– Insufficient acceleration value.
– Fault with gearbox switch.
– Fault with door switch.
– Pads stuck.
– Incorrect multiplex line signals.
If the manual release will not work, see ALP 4
(see the wiring diagrams technical note for the vehicle concerned).
Check that the force applied to the accelerator pedal is sufficient whether or not the vehicle is on a downward
slope or not.
For a vehicle fitted with an automatic transmission, check that the door on the driver's side is not open or
incorrectly closed.
Close the door again and go back through neutral if necessary.
Check that the interior lights have gone out.
Check that the door switch is working correctly:
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code 87H
– connection code MA
Between the door switch, component code 140 and the UCH, component code 645.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Repair if necessary.
Check that the force applied to the accelerator pedal is sufficient and that the accelerator value is sufficient (refer
to the conformity check) whether the vehicle is on a downward slope or not.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.
