If the statuses do not operate as explained above, check the connection and condition of the parking brake
control lever connector.
Repair if necessary.
With the parking brake control lever connector disconnected, check for earth on track 2 of the lever connector
(repair if necessary).
Also check for a 5 V supply (4 V < X < 5 V) on track 7 of the lever connector.
If the supply is not present and the parking brake computer is correctly supplied (no other faults detected by the
diagnostic tool), then contact the Te c h l i n e.
Check the condition and connection of the electronic parking brake computer connectors and their clips
(terminals).
Repair if necessary.
With the parking brake control lever connector disconnected, check the insulation (from earth and to+ 12 V and
the insulation of the 4 wires from each other), the continuity and absence of interference resistance on the
following connections:
Parking brake lever connector: 1216Electronic parking brake computer: 1217

Repair if necessary.
With the parking brake control unit connector disconnected, check the insulation between tracks C2 and D2 of
the computer. If the tracks are in short circuit, replace the lever (see Replacement of components, Part A/
Procedure for replacing an electronic parking brake computer) (see MR405 (Espace IV) or MR395
(Laguna II) or MR370 (Scénic), Mechanical, 37B, Electronic parking brake, Lever: Removal - Refitting or

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.

(except Laguna II, Vel Satis and Espace IV)

track H2
(except Laguna II, Vel Satis and Espace IV)
track G2earth
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.

1. DEF: Incorrect brake cable fitting detected
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.
Special notes:
This fault only appears during configuration of the parking brake.
The fault does not usually come from the electronic parking brake computer.
Conditions for applying the fault finding procedure to a stored fault:
Deal with the fault as if it were present.
Check that the battery voltage PR001 is above 12.5 V.
Check that the mechanical tensioning line is correctly fitted: cables, connections, callipers.
If the parking brake cables are damaged (particularly at the calliper collars), replace both cables (see MR405
(Espace IV) or MR395 (Laguna II) or MR370 (Scénic), Mechanical, 37A, Mechanical component controls,
Parking brake cables: Removal - Refitting or MR353 (Vel Satis), Mechanical, 37B, Automatic parking
brake, Brake cables).
Start the electronic parking brake computer configuration process again: run command VP011 Computer
calibration and initialisation (see Replacement of components).
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.

NOTESNone
This status means there is a + 12 V computer after ignition.
When the ignition is switched off, the status displays: ABSENT.
When the ignition is switched on, the status displays: PRESENT.
If the status does not operate as specified: disconnect the electronic parking brake computer connector to check
the insulation, continuity and the absence of interference resistance on the following connections:
Automatic parking brake computer connector
track H4
(except Laguna II, Vel Satis and Espace IV) track G4 + 12 V
track H2
(except Laguna II, Vel Satis and Espace IV) track G2 earth
Repair if necessary (see the vehicle wiring diagram).
If the connections are correct, the power is correctly supplied to the electronic parking brake computer, but the
fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.
