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.

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.

Repair if necessary (see the vehicle wiring diagram).
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.

Try the diagnostic tool on another vehicle.
Check:
– the connection between the diagnostic tool and the diagnostic sensor (wiring in good condition),
– the connection between the diagnostic sensor and the diagnostic socket (lead in good condition),
– the engine and passenger compartment fuses.
Check for + 12 V battery on track 16, and + 12 V after ignition feed on track 1 and an earth on track 5 and on
track 4 of the diagnostic socket.
Repair if necessary.
