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.

2. DEF
NOTESSpecial notes:
The specification 2.DEF mainly comes from a fault with the
electrical power supply, braking application travel or the
internal force sensor.
If this fault appears after the parking brake has been replaced:
– Check the conformity of the parking brake fitting.
– Check that the battery voltage PR001 is greater than 12.5 V.
– Clear the fault and restart the procedure for fitting the parking brake: see Replacement of components.
Check the fault context when the fault appears: if the battery voltage PR001 is less than 9 V when the fault
appears, then:
– Check the supply line and that the resistance is less than 150 m.
– If there is no sign of a fault on the supply line and if PR019 < 3 and PR022 > 25 and PR018 < 15 then clear
the fault.
Check the fault context when the fault appears: If ET028 Brake switch signal is PRESSED, then:
–If PR019 < 3 and PR022 > 25 and PR018 < 15, then clear the fault.
– The fault can be caused when the user depresses the brake pedal hard, when the parking brake is being
applied. If this is the case, clear the fault.
If there is a loud noise when applying, when maximum braking is requested, then the cause may be mechanical.
Check that the parking brake mechanical tensioning line is correct:
– Parking brake cables correctly fitted.
– Good condition of the parking brake cables (no seizing or deterioration).
– Conformity, condition and proper functioning of the rear brake callipers.
– Condition and conformity of rear brake pads.
– Conformity of rear brakes bleeding.
Carry out the necessary repairs.
Using the diagnostic tool (PARKING sub-function), display the parameters PR005 Force setpoint and PR004
Measured force value. These must have the various values recorded in the conformity check.
If the fault is still present, 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.

NOTESSpecial notes:
The specification 3.DEF mainly comes from a fault with the
electrical power supply or the internal force sensor.
The 4.DEF code is mainly generated by an electrical supply
fault or an internal fault (motor, sensor, etc.). It indicates that
the parking brake is neither applied or released.
If the fault persists, contact the Techline.

electronic parking brake computer (see Replacement of components).
Issue several braking and release commands to confirm the repair.

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).

SUB-FUNCTION: AUTOMATIC RELEASE (CONTINUED 3)
NOTESOnly carry out this conformity check after carrying out a complete check using the
diagnostic tool.
Application conditions: ignition on (forced + after ignition, see Introduction)
Note:
The interpretation of these statuses and parameters is only valid with the
ignition switched on, the statuses and parameters displayed in blue on the
diagnostic tool is information supplied by other computers, which are transmitted via
the multiplex network. If these variables display inconsistent values, check that the
multiplex system test has not shown up any faulty connections. Repair the faulty
multiplex connections before looking for a possible problem with the signals.
Each sub-function in this test is associated with a Fault finding chart.
Special notes:
The diagnostic tool may display the message Computer busy when displaying
statuses and parameters. This message is displayed when the parking brake is
applying or releasing the brake, because the computer gives priority to controlling the
motor before transmitting variables. If this message is displayed, exit the current
screen and then return to it.
