SIGNAL
NOTESSpecial notes:
Although the fault is stored in the computer, it is not caused by ABS/ESP components,
but it indicates that the ESP is deactivated due to an electric power steering frame
transmission fault. Run fault finding on the electric power steering.
Note:
The electric power steering does not always store these transient faults as quickly as
the ABS/ESP system.
If there is no stored fault in the electric power steering computer memory, start the
engine; if no present fault is displayed, contact the Techline. Once the fault in the
electric power steering system has been repaired, clear the ABS/ESP computer fault
memory.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Check the condition and correct locking of the blue PEH connector on the UPC (Vdiag 44) or the grey CT1
connector on the UPC (Vdiag 48).
Carry out a multiplex network test and check the electric power steering system using the diagnostic tool. If the
fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 1 No dialogue with the ABS computer
NOTESSpecial note:
To run fault finding on the vehicle's computers, switch on the ignition in fault finding
mode (forced + after ignition feed), i.e. proceed as follows:
–With the vehicle card in the card reader, press the Start button for more than
5 seconds without starting conditions being met.
Check that the CLIP diagnostic tool is equipped with the latest update available.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty.
If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the
cause could be a faulty computer interfering on the multiplex network. Check the battery voltage and carry out the
operations necessary to obtain the correct voltage (9.5 V < battery voltage < 17.5 V).
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
Check the presence and the condition of the ABS fuses on the passenger compartment fuse board and in the
engine fuse box.
Check that the computer connector is properly connected and check the condition of its connections.
Check the ABS earths (good condition, not corroded, earth screw on top of the ABS unit tight).
Check that the supply to the computer is correct:
–Earth on tracks 1 and 4 of the 46-track connector.
–+ before ignition feed on tracks 2 and 3 of the 46-track connector.
–+ after ignition feed on track 18 of the 46-track connector.
Check that the power supply to the diagnostic socket is correct:
–+ before ignition feed on track 16.
–+ after ignition feed on track 1.
–Earth on tracks 4 and 5.
If dialogue has still not been established after these checks, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 2 Locking of one or more wheels
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Reminder: wheel lock on a vehicle equipped with ABS, or tyre squealing perceived by the customer as locking,
may be part of the normal operation of the system and should not be automatically considered as faults:
–Braking with ABS on very poor roads (significant squealing).
However, if the wheels are actually locking, raise the vehicle in order to be able to turn the wheels and check:
–Possible inversion when connecting the speed sensors.
Using parameters PR001, PR002, PR003 and PR004, rotate the wheels slowly and check the consistency of the
results obtained.
If the value measured is zero, rotate the other wheels to confirm an electrical inversion of the sensors and repair
the wiring harness.
–Possible inversion of pipes on the hydraulic unit.
Use commands AC003 Front left-hand wheel solenoid valves, AC004 Front right-hand wheel solenoid
valves, AC005 Rear left-hand wheel solenoid valves and AC006 Rear right-hand wheel solenoid valves
while depressing the brake pedal and check for the occurrence of 5 locking/unlocking cycles on the wheel
concerned (see Dealing with commands). If the 5 cycles do not occur on the wheel tested (wheel remains
locked), check whether they occur on another wheel to confirm transposed pipes.
If the 5 cycles are not detected on a wheel and the pipes have not been subject to inversion, replace the hydraulic
unit.
Check that the sensor casing is secured when rotating.
Check the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the conformity of the targets using special command SC001 "Check target teeth": condition, number of
teeth = 48.
If the fault is still present after these checks, contact the Techline.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP 3 Pull
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Disconnect one wheel speed sensor. Start the
engine and check that only the ABS fault warning
light comes on. Do not drive the vehicle if the brake
fault warning light is also lit, as the brake limiter
function is no longer guaranteed to operate
correctly. Carry out a road test with the ABS
deactivated.
Is the fault still present under these conditions?
no
Raise the vehicle so that you can rotate the wheels
and check:
–Possible inversion when connecting the speed
sensors.
–Possible inversion of pipes on the hydraulic unit.
To carry out these two tests, refer to and follow the
procedures given in ALP 2.
Check the condition of the ABS targets and that they
conform to specifications.
Also check the sensor/target air gap over one
revolution of each front and rear wheel.
If the fault is still present, contact the Techline.
yesIf the brake pedal travel is relatively long,
bleed the brake circuit.
If the travel is normal, check the tyre
pressures, the front axle, or for any leaks
in the circuit.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
