STOREDRIGHT-HAND FRONT WHEEL TARGET
NOTESSpecial notes:
This fault means that some magnetic poles of the target are not detected by the sensor.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present following a road test at a speed of > 36 mph (60 km/h).
Check for play in the bearing.
Visually inspect the condition of the target and sensor (for dirt, metallic contamination, bearing grease, etc.), and
clean using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check the quality of the mounting of the wheel speed sensor (correct clipping without excessive play).
Check the sensor/target air gap over one wheel revolution: 0.1 mm < front wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
Replace the instrumented bearing if the number of teeth is incorrect.
If all the checks are correct, reconnect the computer and the wheel speed sensor.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a road test.
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.

Fault finding - Dealing with commands
CLEARING
RZ001:Fault memory.
This command is used for clearing the computer's stored faults.
ACTIVATION
AC003:
AC004:
AC005:
AC006:Front left-hand wheel solenoid valves.
Front right-hand wheel solenoid valves.
Rear left-hand wheel solenoid valves.
Rear right-hand wheel solenoid valves.
These commands permit a check on the hydraulics of each wheel.
Position the vehicle on a 2-post lift so that the free rotation of the wheels can be checked.
Keep the brake pedal depressed enough to prevent the wheel being tested from being turned by hand (do not brake
so hard that the anti-lock function operates).
Select and confirm the command for the wheel in question (e.g. Left-hand front wheel solenoid valve, etc.).
Turn the wheel concerned by hand: 5 braking/releasing cycles should be detected.
AC013:Wheel speed sensor supply test.
This command is used to check that voltage pulses of approximately 12 V are detected on the faulty
sensor by a multimeter at the terminals of the sensor connector on the computer side.
You must use command AC013 once only.
AC016:Pump motor test.
This command is used to test the pump motor control circuit.
Select command AC016 Pump Motor Test.
The motor must run for 5 seconds.
AC195:Vehicle speed signal.
This command serves to generate a speed other than 0 mph at the computer's vehicle speed wire output
(Track 23) for users of that signal (xenon bulbs, radio, sunroof).
Note:
This command has no visible effect on the dashboard speedometer needle.
–Xenon headlights: Switch on the dipped headlights and run command AC195. Check for slight
variation in the height of the headlight beam while the command is running (the height of the beam is
adjusted to improve visibility according to vehicle speed).
–Radio: Turn on the radio and make sure that the Adjust volume as a function of speed function is
active. Run command AC195. Check that the volume of the sound increases and then decreases
while the command is running.
–Sunroof: This command has no visible effect on the sunroof. This command changes the activation
threshold of the anti-pinch system (the pressure exerted by the sunroof varies with vehicle speed due
to aerodynamic factors).
AC196:Request to switch on hazard warning lights.
This command sends the UCH a request to switch on the hazard warning lights to test their operation
during emergency braking (depending on UCH configuration).

ALP2 Locking of one or more wheels
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Reminder: locking of wheels on a vehicle equipped with ABS or screeching of tyres, perceived by the customer as
locking, may be related to normal operation of the system and should not automatically be assumed to be a fault:
Braking with ABS system regulation on very poor roads (significant grating).
However, if the wheels are actually locking, lift 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 wheel speed sensor mounting is in good condition.
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 memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP3 Pull
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Disconnect one wheel speed sensor. Start the
engine and ensure 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 thus out of order.
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 perform these tests, refer to and apply the
procedures defined in ALP2. Check the condition
and conformity of the ABS targets. Also check the
sensor/target air gap by rotating each front and rear
wheel one revolution. 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 memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.

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 thus out of order.
Is the fault still present under these conditions?
NO
Normal behaviour linked to the system operation
during the regulation phase, mainly on surfaces with
uneven grip or which are poorly laid.
YESRoad holding fault not related to the ABS.
Check the condition of the brake linings
and that they are to specification and
check the tyre pressures, the front axle,
etc.
AFTER REPAIRClear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

ALP5Unexpected ABS operation at low speeds and slight pedal
pressure
NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Warning: the ABS is sensitive on slippery surfaces (ice, wet tiles, etc.).
It is possible to feel brake pedal vibrations which are associated with the reaction of the system in particular
circumstances, such as:
crossing rumble strips,
tight cornering with lifting of the inside rear wheel.
These vibrations may be linked to simple brake limiter activation, when the pressure on the rear axle is limited.
If the fault is different, check the speed sensor connectors (micro-breaks) as well as the air gaps.
AFTER REPAIRClear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
