NOTESPriority when dealing with a number of faults:
Deal first with faults DF003, DF004, DF028, DF029, DF035, DF041, DF042, DF043,
DF050, DF054, DF055, DF057, DF058 and DF073 if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault recurs after the fault is cleared, with the
ignition switched off and on again (forced + after ignition feed, see Introduction),
and the parking brake released then applied using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
This fault indicates that the electronic parking brake system has been unlocked by the
manual control (if this is the case, check that the handle protector has not been
damaged).
Check that the emergency unlocking handle has not been manually pulled by the
user, which would provoke this fault.
The cables are reset by the parking brake release manual command or automatically
(if the fault is present) when the vehicle is driven at more than 1.2 mph (2 km/h)
(the fault is then stored).
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 there has been no manual use of the emergency unlocking handle and if PR019 > 5,
contact the Techline.
Check that the fault was not provoked by manual usage of the emergency unlocking handle. In this case, it is
normal for the fault to arise; clear the fault.
Carry out a releasing command, then a braking command with the control lever to reset the cables of the parking
brake.
Check the conformity of the parking brake mechanical tensioning line: correctly attached, no breakage.
Check the conformity of the emergency unlocking cable.
Carry out the necessary repairs.
Check that the braking force and maximum braking are operating correctly.
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.

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.

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:

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.

4. DEF: Insufficient braking force
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– a braking command is issued on a slope.
Priorities when dealing with a number of faults:
Deal with faults: DF046 Brake motor / cables connection, DF050 Mechanical
seizure, DF035 Undervoltage, DF058 Parking brake motor current and DF055
Battery undervoltage first if they are present or stored.
Check that the parking brake mechanical tensioning line is correct:
– that the parking brake cables are fitted correctly (refer to the repair procedure),
– that the parking brake cables are in good condition (not seized or deteriorated),
– that the rear brake callipers are correct, in good condition and operating correctly,
– that the rear brake pads are correct and in good condition.
Carry out the necessary repairs.
Using the diagnostic tool statuses screen, display parameter PR003 Slope value.
If the value displayed is not 0 degrees (± 1) on level ground, carry out slope initialisation again (actuator control
mode menu).
Using the diagnostic tool parameters screen, display the following parameters: PR005 Force setpoint and PR004
Measured force value. These must show the various values recorded in the conformity check.
Clear the fault, switch off the ignition for 5 minutes (vehicle doors and windows closed), switch the ignition back
on and repeat a braking command on a slope.
If the fault reappears, switch off the ignition and disconnect the computer supply fuse (fuse F23 of the engine fuse
box, refer to the wiring diagram) for approximately 1 minute.
Reconnect the fuse, switch the ignition on and establish dialogue with the computer. Apply the brake to check
whether the fault recurs.
If the fault reappears despite the above tests, or if the parameter values are not within conformity check
tolerances while the brake is applied, then contact your Techline.
AFTER REPAIRClear the fault memory.
Follow the instructions to confirm repair.
If 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 possible faults.

1. DEF
NOTESSpecial notes:
The fault does not usually come from the electronic parking
brake computer.
This fault appears as present if the computer supply voltage
is less than 10.3 V, and becomes stored once the voltage
rises back above 10.5 V.
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.
Note:
This fault may appear if starting is very difficult.
Conditions for applying the fault finding procedure to
a stored fault:
Apply this fault finding procedure if the fault reappears as
present after the ignition has been switched on (forced
+ after ignition feed, see Introduction).
2. DEF
NOTESNote:
This fault only affects Vdiag 0D.
Priorities when dealing with a number of faults:
Deal first with faults DF046 Brake motor/cables
connection, DF042 Force sensor, DF035 Undervoltage,
DF041 Slope sensor, DF049 Brake application, DF054
Battery voltage too high and DF055 Battery
undervoltage if they are present or stored.
If none of these faults is present or stored, the parking brake
computer is not normally the cause.
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.
