C/ CLUTCH DATA BACKUP (for vehicles with a manual gearbox)
Purpose of the procedure:
The data saved relates to the clutch engagement point. This is important when the clutch wears, because this data
enables the parking brake to release electronically when the clutch enables the vehicle to move off.
If this data cannot be retrieved from the old computer (impossible to establish dialogue with the diagnostic tool) or a
new clutch has been fitted, the new computer has to be programmed with the clutch engagement point: drive the
vehicle, downshifting at least 30 times (from 5
th to 4th gear) before returning the vehicle to the customer.
If the clutch data is not recorded in the new computer, the operation of the assisted brake on steep slopes will be
impaired when first used.
Perform the following operations:
– establish dialogue with the computer,
– select the repair mode menu on the diagnostic tool.
– open the programming menu,
– run function SC005 Backup clutch pedal programming (the data is written to a file that is automatically
selected when the new computer is programmed).
– replace the electronic parking brake computer (see MR405 (Espace IV) or MR395 (Laguna II) or
MR370 (Scénic), Mechanical, 37B, Electronic parking brake, Control unit: Removal - Refitting or
MR353 (Vel Satis), Mechanical, 37B, Automatic parking brake, Control unit),
– follow the procedures described in sections A and B.
D/ CLUTCH DATA ENTRY (for vehicles with automatic transmission)
The initialisation must be carried out (sections A and B).
Perform the following operations:
– establish dialogue with the computer,
– select the repair mode menu on the diagnostic tool.
– open the programming menu,
– run function: SC006 Enter clutch pedal programming.
– check that the electronic parking brake is operating correctly, including the assisted release function. IMPORTANT:
Do not apply this procedure in the event of a clutch fault.
Note:
– For vehicles fitted with an automatic gearbox, command SC005 Save clutch pedal programming is
unavailable.
– Command SC006 Enter clutch pedal programming, is also unavailable if command SC005 has not already
been activated.

ENTER CLUTCH PEDAL PROGRAMMING
NOTESSpecial notes:
The commands are found in the tool's repair mode, Programming button.
Once the electronic parking brake computer has been changed.
Run command SC006 Enter clutch pedal programming after running command SC005 Backup clutch pedal
programming.
Test braking and release, and starting the electronic parking brake computer when applied, to check conformity.
Park the vehicle on a level surface.
– Select the diagnostic tool's Repair mode menu.
– From the tool's navigation menu, select Programming.
– Run command SC006 Enter clutch pedal programming.
Note:
When a new electronic parking brake computer is initialised, the angle sensor is calibrated after running
command VP011 Computer calibration and initialisation.
AFTER REPAIRRepeat the conformity check from the start.

SLOPE INITIALISATION
NOTESSpecial notes:
The commands are found in the tool's repair mode, Programming button.
Using the diagnostic tool's automatic release sub-function screen, display parameter PR003 Slope value.
If the value displayed is not 0d° ± 2 on level ground: run the command by following the procedure described
below.
Park the vehicle on a level surface.
– Select the diagnostic tool's Repair mode menu.
– From the tool's navigation menu, select Programming.
– Run command SC008 "Slope initialisation".
– Check the conformity of parameter PR003 Slope value.
Note:
When a new electronic parking brake computer is initialised, the angle sensor is calibrated after running
command VP011 Computer calibration and initialisation.
AFTER REPAIRRepeat the conformity check from the start.
