NOTESPriorities when dealing with a number of faults:
This fault must be dealt with first.
Special notes:
Before replacing the electronic parking brake computer, save the data from the old
computer (for vehicles fitted with a manual gearbox).
For this operation, see Replacement of components.

NOTESNone.
If the fault is present or stored, contact the Techline.
3. DEF
NOTESSpecial notes:
The fault does not usually come from the electronic parking
brake computer.
This fault indicates that the computer has detected several
losses of feed (micro-breaks).
Note:
This fault may be caused by several battery disconnections
or a vehicle power supply fault.
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,
then clear the fault:
do not take this fault into account.
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 forced
+ after ignition feed has been switched off and on again
(seeIntroduction).
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.

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.

COMPUTER CONFIGURATION
1. DEF: Configuration absent or incorrect
NOTESSpecial notes:
Deal with this fault only after the computer has been replaced.
If it appears when the electronic parking brake computer is not new, contact the
Techline.
This fault indicates that the parking brake control unit has not been calibrated or has
been calibrated incorrectly.
This fault causes the electronic parking brake to operate incorrectly, in particular for
the assisted release function.
Display status ET024 System operation on the main screen of the diagnostic tool.
This status should be CUSTOMER MODE. If it is FACTORY MODE, initialise the computer by running command
VP011 Computer calibration and initialisation (see Replacement of components).
Test that the parking brake is operating correctly by applying it, applying it completely (handle pulled right up for
5 seconds) and releasing it.
Check the validity of parameter PR003 "Inclination value".
Calibrate the sensor if necessary (SC008 Slope initialisation).
If necessary, reconfigure the application and release functions as requested by the customer with CF007 Vehicle
configuration and see Configurations and programming.
If the above procedure does not resolve the fault (fault still present), recalibrate the computer (command VP011
Computer calibration and initialisation on the diagnostic tool).
During this stage, check that the vehicle criteria are correctly entered (screen 2 stage 1).
If the fault is still present, contact the Techline without clearing the faults.
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.

NOTESConditions for applying the fault finding procedure to
a stored fault:
The fault is declared present when the ignition is switched

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:

Repair if necessary.
Disconnect the clutch pedal position sensor connector to check, with the ignition switched on and the electronic
parking brake computer connector connected, the presence of a 5 volt supply, by measuring between tracks 1
and 3 of the sensor (+ 5 V on track 1 and earth on track 3).
If the 5 V supply is not present and the connections previously checked are correct, contact the Techline.
With the clutch pedal position sensor connector disconnected, measure the sensor resistance between tracks 1
and 3 of the sensor.
Replace the sensor if its resistance is not 5200  ± 520 .
If the fault is still present, contact the Techline.
1. DEF; 2. DEF
NOTESConditions for applying the fault finding procedure to
a stored fault:
Engine at idle speed, and gear engaged for 5 seconds.
Check the operation of statuses ET016 Manual gearbox gear lever position and ET017 Reverse gear
engaged and the absence of any incorrect contacts.
If not correct, check the operation of the gearbox sensor.
Check that the clutch pedal position sensor is fitted correctly: the "arm" of the potentiometer should be inserted
correctly into its mounting lug (neither above nor below).
Using the diagnostic tool, display parameter PR006 Clutch pedal position on the main data screen (see the
conformity check values).
Check the conformity of the pedals.
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.

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.

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.
