STOREDVEHICLE MOVEMENT WITH MAXIMUM APPLICATION
1. DEF: The computer has detected vehicle movement when parked (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.
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).
Issue several braking and release commands to confirm the repair.
Deal with any other faults.

STOREDUNDERVOLTAGE
1. DEF: Insufficient feed voltage during the command
NOTESPriority in the event of a number of faults:
Deal with fault DF055 Battery undervoltage first if it is present or stored.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault reappears after the ignition has been
switched off and on again (+ forced after ignition feed: see Introduction) and an
application or release request using the control lever.
Special notes:
This fault is a power supply fault and does not usually stem from the electronic
parking brake computer.
This fault does not indicate computer feed undervoltage but a significant drop in
voltage to the parking brake motor while the command is being issued.
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.
Disconnect the electronic parking brake computer connector to check the conformity of the supplies and to
check the insulation, continuity and the absence of interference resistance on the following connections:
Electronic parking brake computer connector
track H4
(except Laguna II, Vel Satis and Espace IV)
track G4+12V
track H2
(except Laguna II, Vel Satis and Espace IV)
track G2earth
Repair if necessary (see the vehicle wiring diagram).
Apply the brake and then release it (engine running) to check that during the command the voltage measured at
the fuse does not drop below 10.5 V.
Make the repairs necessary for the parking brake computer electrical supply to be correct (equal to the battery
voltage).
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: Multiplex signals absent or values invalid (fault with the computer generating
the signal or multiplex line connection fault)
NOTESPriority in the event of a number of faults:
Deal with faults DF055 Battery undervoltage and DF052 Multiplex network first if
they are present or stored.
Deal with any injection computer faults first.
The fault does not usually come from the electronic parking brake computer.
Note:
If there is a multiplex line fault like this one, the parking brake loses its assisted
application and release functions.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault reappears as present or stored after a
fault has been cleared, and the ignition has been switched off and on again (forced
+ after ignition feed: see Introduction).
Special notes:
This fault only relates to multiplex signals received from the injection computer.
This fault indicates either that there is no transmission, or that the signals received by
the parking brake are inconsistent.
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 section.
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 < 10, clear the fault:
