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.

2. Scénic II:
Check the continuity and absence of interference resistance on the following connection:
– connection code H51.
Between the injection computer, component code 120 and the clutch pedal switch, component code 675.
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).
Reconfigure the vehicle clutch curve by applying the special command SC006 Enter clutch pedal
programming.
Test the assisted brake release.
Check the condition of the clutch system (wear of the different components, possible build-up of grease on
surfaces in friction).
Repair if necessary.
Carry out a multiplex network test (see 88B, Multiplexing) and check for any potential faults on the injection
computer (see 13B, Diesel injection or 17B, Petrol injection), the automatic gearbox computer (see 23A,
Automatic gearbox) and the UCH computer (see 87B, Passenger compartment connection unit).
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.

ALP4 Assisted braking fault (when the engine is stopped)
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).
Check for any potential faults in the ABS computer (see 38C, Anti-lock braking system), the UCH computer
(see 87B, Passenger compartment connection unit) and the injection computer (see 13B, Diesel injection or
17B, Petrol injection) to ensure that they have actually received a request to stop the engine.
Test the application of the electronic parking brake with the engine switched off.
Incorrect signal faults on the multiplex line.
Run a multiplex network test (see88B, Multiplex).
When the engine stalls, the automatic brake application function is not active.
Check the + 12 V supply, the insulation, continuity and the absence of interference resistance on the
following connection:
– connection code BP2
Between the electronic parking brake computer, component code 1217 and the battery, component code 107.
If the continuity is correct, test the charging circuit (see Technical Note 6014A, Checking the charging circuit).
Repair if necessary.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.
