NOTESPriorities when dealing with a number of faults:
Deal with fault DF007 Rear left-hand wheel speed sensor circuit first if it is present.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test (in excess of 12 mph (20 km/h)
for 2 minutes).
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
Check that the braking system (condition of brake pads, sealing, sticking, bleed, bearing clearance, etc.) is in
good condition.
Visually inspect the condition of the target (for clogging, 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 that the wheel speed sensor mounting is in good condition.
Check the conformity of the target (condition, number of teeth = 48) using the special command SC001 Check
target teeth.
If there is non-conformity, replace the complete drum.
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.

If there is non-conformity, replace the target.
Check the connection and condition (possible damage to the wiring) of the connector of component 1094.
Check the connection and condition (possible damage to the wiring) of the connector of component 152.
If the connector is faulty (see Technical Note 6015A, Repairing electrical wiring, wiring: Precautions for
repair), repair the connector, otherwise replace the wiring.
Check for a voltage of approximately 12 V between the two connections of component 152 near
component 1094.
If a 12 V feed is not present, contact the Techline.
If all the checks are in order, swap the 2 front wheel speed sensors. Clear the computer fault memory.
Switch off the ignition. Switch the ignition back on and carry out a road test.
If a fault, which was initially registered as DF229 front right-hand wheel speed has become present DF230
front left-hand wheel speed, replace the wheel speed sensor (see MR411 Mechanical systems, 38C, Wheel
speed sensor: Removal - Refitting).
If the fault stays on the same side, the target is faulty, replace the active sensor bearing.

NOTESConditions of use of the command.
Ignition on, engine stopped and vehicle speed zero.
Before using the commands, check that the battery is fully charged.
The previous 4 commands allow the hydraulic check of each wheel.
Raise the vehicle in order to be able to rotate the wheels, and check that they rotate freely.
Keep the brake pedal depressed to prevent the wheel being tested from being turned by hand (do not brake so
firmly that full braking power is reached).
Select and confirm the command of the wheel being examined (e.g. Front left-hand wheel solenoid valves, etc.)
Turn the wheel concerned by hand; 5 locking/unlocking cycles should be noted on the wheel.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
