Disconnect the electronic parking brake computer connector (under the body near the rear axle) to check the
conformity of the power supply (this must equal the voltage measured at the battery terminals ± 0.5 V).
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
Note:
If the electrical supply is correct, check that the supply has not been cut off by moving the electrical harness
(near to the intermediate connector under the front left-hand seat at the computer connector).
Repair if necessary (see the vehicle wiring diagram).
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.

NOTESPriorities when dealing with a number of faults:
Deal with faults DF035 Undervoltage, DF055 Battery undervoltage and DF054
Battery voltage too high first, if they are present or stored.
Special notes:
The fault does not usually come from the electronic parking brake computer.
The fault should only be displayed on a vehicle fitted with a manual gearbox. If it is
displayed on an automatic transmission, check the configurations.
The sensor should be replaced in + after ignition feed, if not this fault may occur.
If the fault appeared following replacement of the clutch position sensor, check the
procedure and repeat it in + after ignition feed if necessary, after clearing the fault.
If the fault cannot be cleared, disconnect the clutch sensor under + after ignition
feed, then reconnect it.
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.
CC.0; CC.1; 3.DEF
NOTESConditions for applying the fault finding procedure to
a stored fault:
The fault is declared present when the ignition is switched
on (forced + after ignition feed, see Introduction).
Check the connection and condition of the clutch pedal position sensor connector.
Repair if necessary.
With the clutch pedal position sensor connector disconnected, check the insulation, continuity and absence of
interference resistance on the following connections:

Deal with faults DF035 Undervoltage, DF055 Battery undervoltage and DF054
Battery voltage too high first, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the forced + after ignition is switched on
(seeIntroduction) and an application request using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
Note:
After a release request, the fault becomes stored.
Replacing the lever with the parking brake applied may cause this fault. If this fault
appears after replacing the lever, release the parking brake and carry out the
procedure again.
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 < 3, clear the fault: do not take this fault into account.
Check that the electronic parking brake control lever connector is in good condition and also check its clips
(terminals).
Repair if necessary.
Check that there is a 12 V + before ignition supply on track 6 of the electronic parking brake control lever:
see wiring diagram.
Repair if necessary.
Disconnect the electronic parking brake control lever connector in order to check the insulation, continuity and
absence of interference resistance on the following connection:

Repair if necessary.
If the fault is still present, replace the parking brake control lever (the indicator light cannot be separated).
If the fault persists, contact the Techline.

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.

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).
