NOTESPriority when dealing with a number of faults:
Deal first with faults DF047 Manual control, DF035 Undervoltage, DF055 Battery
undervoltage and DF054 Battery voltage too high, 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 an application request using the control lever.
The fault does not usually come from the electronic parking brake computer.
Special notes:
The braking switch is in fact the first contact of the lever (the lever travels about
3mm).
This fault appears naturally when the lever is disconnected.
Note:
The fault warning light comes on 10 seconds after the fault appears.
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.
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.

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.

NOTESPriorities when dealing with a number of faults:
Deal with faults: DF035 Undervoltage, DF055 Battery undervoltage and DF054
Battery voltage too high first, if they are present or stored.
Note:
The fault does not usually come from the electronic parking brake computer.
The fault is only stored after the brakes have been applied 3 times with the control
level.
Conditions for applying the fault finding procedure to a stored fault:
Deal with the fault as if it were 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 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).
Also check for a 5 V supply (4 V < X < 5 V) on track 7 of the lever connector.
If the supply is not present and the parking brake computer is correctly supplied (no other faults detected by the
diagnostic tool), then contact the Te c h l i n e.
Check the condition and connection of the electronic parking brake computer connectors and their clips
(terminals).
Repair if necessary.
With the parking brake control lever connector disconnected, check the insulation (from earth and to+ 12 V and
the insulation of the 4 wires from each other), the continuity and absence of interference resistance on the
following connections:
Parking brake lever connector: 1216Electronic parking brake computer: 1217
track 9
track 7
track 10
track 4track D2
track C2
track C3
track D3
Repair if necessary.
With the parking brake control unit connector disconnected, check the insulation between tracks C2 and D2 of
the computer. If the tracks are in short circuit, replace the lever (see Replacement of components, Part A/
Procedure for replacing an 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.

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.

If there is a stored fault, refer to the statuses and parameters when it appears.
