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.
