PRESENT
OR
STOREDVEHICLE MOVEMENT WITH MAXIMUM APPLICATION
1. DEF: Rear wheel movement with parking brake applied
2. DEF: Front wheel movement with parking brake applied
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.
Deal with any other faults.

ALP3 Assisted release too early or too late
NOTESOnly consult this customer complaint after a full check using the diagnostic tool
(no present or stored faults).
(see the wiring diagrams technical note for the vehicle concerned).
Assisted release may be activated too late if a trailer is attached to the vehicle.
Test assisted release without the trailer.
Test the braking system:
Look for any areas where the brake pads may be sticking (due to ice, salt, etc.).
Check that the brake piston is operating correctly.
Repair if necessary.
Check the clutch sensor positioning:
●Espace IV and Vel Satis
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code 150K,
– connection code 150L,
– connection code 26X.
Between the electronic parking brake computer, component code 1217 and the clutch position sensor,
component code 1057.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace the wiring.
Reposition it, if necessary.
Replace the clutch sensor if necessary (see MR405 (Espace IV) or MR395 (Laguna II) or MR370 (Scénic),
Mechanical, 37A, Mechanical component controls, Clutch pedal position sensor: Removal - Refitting or
MR353 (Vel Satis ph 1), Mechanical, 37A, Mechanical component controls, Clutch pedal or MR402 (Vel
Satis ph 2), Mechanical, 37A, Mechanical component controls, Clutch pedal switch: Removal - Refitting).
●Laguna II and Scénic II
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code 150Q,
– connection code 150L.
Between the electronic parking brake computer, component code 1217 and the clutch pedal sensor,
component code 675 (see section 87B, UCH, Door switch).
1. Laguna II:
Check the continuity and absence of interference resistance on the following connection:
– connection code 86D
Between the injection computer, component code 120 and the clutch pedal switch, component code 675.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.
