STOREDVEHICLE MOVEMENT WITH MAXIMUM APPLICATION
1. DEF: Rear wheel movement with parking brake applied
2. DEF: Front wheel movement with parking brake applied
NOTESPriorities when dealing with a number of faults:
First deal 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.
Conditions for applying the fault finding procedure to a stored fault:
Apply the fault finding procedure even if the fault is stored.
Note:
The fault does not remain present after it has been detected.
1. DEF
NOTESSpecial notes:
– This fault indicates that the electronic parking brake
computer detected rear wheel movement although the
parking brake was applied with maximum force.
– It may be associated with 2.DEF.
If this fault is not associated with the faults mentioned
above, check the conformity of the parking brake's
mechanical force line:
– Condition and conformity of rear brake pads.
– Parking brake cables correctly fitted.
– Good condition of the parking brake cables (no seizing
or deterioration).
– Conformity, condition and correct operation of the rear
brake callipers.
This fault is an operational warning. Check the context in
which it appears.
It may appear during:
– incorrect use of a roller test bench which drives the
rear wheels (MOT test),
– forced assisted release when starting, when the
starting conditions have not been met,
– vehicle overload on a very steep slope (maximum
permissible all-up weight exceeded + angle > 18°: e.g.
towing a trailer or a caravan).
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.

Conditions for applying the fault finding procedure to a stored fault:
Apply the fault finding procedure even if the fault is stored.
Note:
The fault does not remain present after it has been detected.
Special notes:
– this fault indicates that the electronic parking brake computer detected movement
of the vehicle although the parking brake was applied.
– if this fault is present, with the ignition on, the buzzer on the instrument panel is
activated (when the vehicle is moving with the parking brake applied).
This fault is an operational warning. Check the context in which it appears.
It may appear during:
– an application request, whilst the vehicle is still being driven,
– forced assisted release when starting, when the starting conditions have not
been met,
– parked on a steep slope with slippery surface,
– incorrect use of a roller test bench (MOT test).
Only for Vdiag 08 and 0C:
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction section.
If the fault is stored and PR018 = 0 and PR022 > 25, 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).

1. DEF: Parking brake unlocked by the emergency handle
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.

1. DEF: Inconsistent braking value
2. DEF: Normal brake application value not reached
3. DEF: Normal brake release value not reached
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.
