ALP2 Will not release
NOTESOnly consult this customer complaint after a full check using the diagnostic tool
(no present or stored faults).
The main causes of the brake not releasing are:
– Driver's door incorrectly closed (on vehicles with an automatic transmission).
– Insufficient acceleration value.
– Fault with gearbox switch.
– Fault with door switch.
– Pads stuck.
– Incorrect multiplex line signals.
If the manual release will not work, see ALP 4
(see the wiring diagrams technical note for the vehicle concerned).
Check that the force applied to the accelerator pedal is sufficient whether or not the vehicle is on a downward
slope or not.
For a vehicle fitted with an automatic transmission, check that the door on the driver's side is not open or
incorrectly closed.
Close the door again and go back through neutral if necessary.
Check that the interior lights have gone out.
Check that the door switch is working correctly:
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection code 87H
– connection code MA
Between the door switch, component code 140 and the UCH, component code 645.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Repair if necessary.
Check that the force applied to the accelerator pedal is sufficient and that the accelerator value is sufficient (refer
to the conformity check) whether the vehicle is on a downward slope or not.
AFTER REPAIRCarry out a check using the diagnostic tool.
Deal with any other faults.

For a vehicle fitted with an automatic gearbox:
Check the connection and condition of the automatic gearbox multifunction switch, component code 779.
Check the connection and condition of the automatic gearbox computer, component code 119.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance of the following connections:
●5DF between components 779 and 119,
●5DG between components 779 and 119,
●5DH between components 779 and 119,
●5CF between components 779 and 119.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
For a vehicle fitted with a manual gearbox:
Check the connection and condition of the reversing lights sensor, component code 1109.
Check the connection and condition of the Protection and Switching Unit, component code 1337 (Only for Scénic
II), or the UCH, component code 645 (Only for Vel Satis phase 1 and phase 2, Laguna II phase 2, Espace IV
phase 1 and phase 2).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Check the insulation, continuity and the absence of interference resistance of the following connection:
●H66P between components 1109 and 1337 (Only for Scénic II),
●H66P between components 1109 and 645 (Only for Vel Satis phase 1 and phase 2, Laguna II phase 2,
Espace IV phase 1 and phase 2).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRCarry out a check using the diagnostic tool.
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.

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),

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.
