NOTESPriority when dealing with a number of faults:
Deal first with faults DF047 Manual control, DF035 Undervoltage and DF055
Battery voltage too low, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
This fault must be dealt with first.
Special notes:
The fault does not usually come from the electronic parking brake computer.
The redundant brake switch is the second contact of the lever (maximum lever travel).
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
If the statuses do not operate as explained above, check the connection and condition of the parking brake
control lever connector.
Repair if necessary.
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.

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 10 track C3
Repair if necessary.
With the parking brake control lever connector disconnected, check for earth on track 2 of the lever connector.
Repair if necessary.
If the fault persists, check the redundant braking switch:
Lever in rest position: insulation between tracks 2 and 10 of the lever.
Lever fully applied: continuity between tracks 2 and 10 of the lever.
Replace the parking brake control lever if it does not function as indicated (see MR405 (Espace IV), 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.
