4. FAULT FINDING PROCEDURE (CONTINUED)
Wiring check
Fault finding problems
Disconnecting the connectors and/or handling the wiring harness may temporarily remove the cause of a fault and
create other faults.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Continuity and insulation check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

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: 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.

1. DEF: Battery voltage too high
NOTESPriorities when dealing with a number of faults:
Deal first with faults DF003 (1.DEF; 2.DEF), DF004, DF028, DF029, DF041, DF042,
DF043, DF050, DF057, DF058 and DF073.
Conditions for applying the fault finding procedure to a stored fault:
Apply this fault finding procedure if the fault appears as present again after the ignition
has been switched on
(forced + after ignition feed, see Introduction).
Special notes:
The fault does not usually come from the electronic parking brake computer.
This fault appears as present if the computer supply voltage is greater than 16.5 V,
and becomes stored when the voltage goes back down below 15.7 V.
Note:
Using another battery for a boost when starting may trigger this 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, clear the fault:
do not take this fault into account.
Check the charging circuit: the alternator should not supply a voltage of less than + 12 V or greater than + 14.4 V
(engine at idle speed).
Check the alternator and the regulator.
Carry out the necessary repairs.
If the fault is still present, check that no electrical system using the same supply fuse as the electronic parking
brake computer is faulty.
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.

2. DEF
NOTESSpecial notes:
This fault is generated after the automatic parking brake is
switched on whilst driving or following an internal reset.
With the anti-lock braking system, this detection is active at
> 0.6 mph (> 1 km/h), otherwise the multiplex signal
emitted by the injection computer must be 1.
Note:
The driver is only informed of this fault after 16 successive
detections.
This fault may be due to battery disconnections or vehicle
supply faults, in which case it is associated with fault 1.DEF
(battery voltage too low) dealt with previously.
If the frequency counter (PR016) > 3 and if the onboard network (battery, wiring) analysis does not bring up any
present or stored fault under battery voltage, contact the Techline.
Check that the battery, battery - starter - alternator connection lead, battery earth - chassis lead and the chassis
earth - engine and transmission assembly lead are in good condition.
Repair if necessary.
Check the charging circuit: the alternator should not supply a voltage of less than + 12 V or greater than + 14.4 V
(engine at idle speed).
Carry out the necessary repairs.
