NOTESPriorities when dealing with a number of faults:
Deal with faults DF035 Undervoltage, DF055 Battery undervoltage and DF054
Battery voltage too high first, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the forced + after ignition is switched on
(seeIntroduction) and an application request using the control lever.
Special notes:
The fault does not usually come from the electronic parking brake computer.
Note:
After a release request, the fault becomes stored.
Replacing the lever with the parking brake applied may cause this fault. If this fault
appears after replacing the lever, release the parking brake and carry out the
procedure again.
Only for Vdiag 08, 0C and 0D:
If there is a stored fault, refer to the statuses and parameters when it appears.
Explanation of counters: see Introduction section.
If the fault is stored and PR018 = 0 and PR022 > 25 clear the fault: do not take this
fault into account.
If the fault is stored and PR019 < 3, clear the fault: do not take this fault into account.
Check that the electronic parking brake control lever connector is in good condition and also check its clips
(terminals).
Repair if necessary.
Check that there is a 12 V + before ignition supply on track 6 of the electronic parking brake control lever:
see wiring diagram.
Repair if necessary.
Disconnect the electronic parking brake control lever connector in order to check the insulation, continuity and
absence of interference resistance on the following connection:
Electronic parking brake control lever connector:
1216Electronic parking brake computer connector:
1217
Track 5 Track C4
Repair if necessary.
If the fault is still present, replace the parking brake control lever (the indicator light cannot be separated).
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.

Deal first with faults DF047 Manual control, DF035 Undervoltage, DF055 Battery
undervoltage and DF054 Battery voltage too high, if they are present or stored.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the ignition is switched on (forced + after ignition
feed, see Introduction) and an application request using the control lever.
The fault does not usually come from the electronic parking brake computer.
Special notes:
The braking switch is in fact the first contact of the lever (the lever travels about
3mm).
This fault appears naturally when the lever is disconnected.
Note:
The fault warning light comes on 10 seconds after the fault appears.

NOTESSpecial notes:
This fault indicates a malfunction due to not following procedures correctly:
replacement or reconfiguration of the electronic parking brake computer was carried
out with a present fault.
Conditions for applying the fault finding procedure to a stored fault:
Deal with the fault as if it were present.
Using the diagnostic tool, run fault finding on the electronic parking brake computer.
Deal with other present or stored faults first.
Carry out any necessary repairs. Clear the fault.
If no fault is displayed on the diagnostic tool, carry out a conformity check to check the conformity of the
parking brake system.
If the conformity check and fault finding with the diagnostic tool have not enabled the fault to be solved
(seeIntroduction) for fault warning light management, to find out which components may be causing the
malfunction.
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.

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.
