NOTESPriority when dealing with a number of faults:
Deal first with faults DF003, DF004, DF028, DF029, DF035, DF041, DF042, DF043,
DF047, DF050, DF054, DF055, DF057, DF058 and DF073 if they are present or
stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition is switched on (forced + after ignition
feed, see Introduction) and a brake release request using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
8 applications (in 2 seconds) using the control lever without pressing the release
switch causes the fault to appear as present.
Only for Vdiag 08, 0C and 0D:
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction.
If the fault is stored and PR018 = 0 and PR022 > 25 clear the fault: do not take this
fault into account.
If the fault is stored and PR019 < 3, clear the fault: do not take this fault into account.
Using the diagnostic tool (PARKING sub-function), check the operation of the parking brake control lever.
With the ignition switched on, statuses ET008, ET009 and ET010 should operate as follows:
ET008 "Engagement
switch position"ET009 "Redundant
braking switch position"ET010 "Release switch
position"
Lever at rest INACTIVE INACTIVE RELEASED
Lever pulled slightly
(3 mm travel)ACTIVE INACTIVE RELEASED
Lever pulled to end of
travelACTIVE ACTIVE RELEASED
Lever pulled and release
switch pressedACTIVE ACTIVE PRESSED
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.

If the statuses do not operate as explained above, check the connection and condition of the parking brake
control lever connector.
Repair if necessary.
With the parking brake control lever connector disconnected, check for earth on track 2 of the lever connector.
Repair if necessary.
Check the connections and condition of the electronic parking brake computer connectors and their clips
(terminals) and its intermediate connector (under front left-hand seat).
With the parking brake control lever connector disconnected, check the insulation, continuity and absence of
interference resistance on the following connection:
Parking brake lever connector: 1216Electronic parking brake computer: 1217
track 4 track D3
Repair if necessary.
If the fault is still present, check the release switch.
Lever in rest position: insulation between tracks 2 and 4 of the lever,
Lever fully applied and release switch pressed: continuity between tracks 2 and 4 of the lever.
Replace the parking brake control lever if it does not function as indicated (see Replacement of components,
Part A/ Procedure for replacing the electronic parking brake computer) (see MR405 (Espace IV) or MR395
(Laguna II) or MR370 (Scénic), Mechanical, 37B, Electronic parking brake, Lever: Removal - Refitting or
MR353 (Vel Satis), Mechanical, 37B, Automatic parking brake, Lever).
If the fault persists, contact the Techline.
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.
