NOTESSpecial notes:
This fault indicates that the wheel speeds are inconsistent with each other. The
computer does not know how to determine which one is faulty.
Priorities when dealing with a number of faults:
Deal with faults DF006, DF007, DF026 and DF027 first, even if they are stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test at a speed of over 36 mph (60 km/h) on
a winding road.
Check the condition of the axles (impacts, damage, etc.) and the conformity and good condition of the tyres.
Ensure that the braking system is in good condition (condition of the linings, tightness, grip, bleeding, bearing play,
lubricant on the targets, etc.).
Check the quality of the mounting of the wheel speed sensors (correct clipping without excessive play).
Check the sensor/target air gap over one wheel revolution: 0.1 mm < 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.
Repair if necessary.
Carry out a visual check on the connection and condition of the sensor and computer connectors
Check the connection and condition of the connections (tracks 31, 32, 33 and 34) of the R2 black 52-track
intermediate connection under the front left seat.
Repair if necessary.
If all the checks are correct, clear the computer's fault memory.
Exit the fault finding procedure 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.

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).

SPECIAL COMMANDS
SC001:Check target teeth.
This command tests the condition of the teeth on each wheel.
Select command SC001 Check target teeth. The test result should indicate 48 sprockets.
SC006:Bleed the hydraulic unit and brake circuits.
This command must be used only if abnormally long brake pedal travel is noted during a road test with
ABS control (the system must have been bled beforehand by the usual method).
Select the SC006 "Bleed hydraulic unit and brake circuit" command and follow the instructions given
by the diagnostic tool.
