NOTESPriorities when dealing with a number of faults:
This fault must be dealt with first.
Special notes:
The force sensor is internal to the electronic parking brake
computer; it cannot be separated.
Before replacing an electronic parking brake computer,
save the data from the old computer (for vehicles fitted
with a manual gearbox).
For this operation, (see Replacement of components).
Contact the Techline without clearing the faults.

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.

Using the diagnostic tool (PARKING sub-function), check the operation of the parking brake control lever. With
the ignition on, statuses ET008, ET009, ET010 should operate as follows:

If the statuses do not operate as explained above, check the connection and condition of the parking brake
control lever connector.
Repair if necessary.
Check the condition and connection of the parking brake computer connectors and their clips (terminals).
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.

With the parking brake control lever connector disconnected, check the insulation, continuity and absence of
interference resistance on the following connections:
Parking brake lever connector: 1216Electronic parking brake computer: 1217
track 9
track 7track D2
track C2
Repair if necessary.
With the parking brake control lever connector disconnected, switch on the ignition and check for a 5 V supply
(4 V < X < 5 V) on track 7 of the lever connector. If the power 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.
If the fault is still present, measure the resistance of the braking switch between tracks 7 and 9 of the parking
brake control lever.
Replace the lever (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 resistance of the brake application switch is not approximately:
– Lever in rest position: 2700  ± 100 
– Lever pulled: 172  ± 15 .
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.
