Priorities when dealing with a number of faults:
Deal first with faults DF090 Front right-hand wheel target, DF091 Front left-hand
wheel target, DF092 Rear right-hand wheel target and DF093 Rear left-hand wheel
target even if they are stored.

NOTESConditions for applying the fault finding procedure to
stored faults:
The fault is declared present after a road test.
Check the quality of the mounting of the wheel speed sensors (correct clipping without excessive play).
Check the conformity of the targets (condition, number of teeth = 48) using the specific command SC001 Check
target teeth for each wheel.
Are the numbers of teeth correct?
YESVisually inspect the condition of the axles (impacts, deformations, etc.) and check that
the tyre mountings conform and are in good condition (see MR 411, Mechanical, 35A,
Wheels and tyres, Identification).
Ensure that the braking system is in good condition (condition of the linings, tightness,
grip, bleeding, bearing play, lubricant on the targets, etc.).

Question the customer to find out if he regularly drives on
a speed track. If this is the case, follow the procedure below
but never replace component 583.
Clear the ESP offsets using command RZ011 Sensor offset.
Position the steering wheel straight ahead (the wheels must be directly in line with the vehicle) and read the value
of the steering wheel angle using the parameter PR033 "Steering wheel angle".
If the value is not close to 0 ± 5˚, calibrate component 583 using command VP003 Steering wheel angle sensor
(see Configurations and programming).
Clear the ESP sensor offsets using command RZ011 Sensor offset.
With the steering wheel horizontal and the front wheels set straight ahead, turn the steering wheel a quarter of
a turn to the left.
Using parameter PR033 Steering wheel angle, check that the steering wheel angle value is close to - 90.
With the steering wheel horizontal and the front wheels set straight ahead, turn the steering wheel a quarter of
a turn to the right.
Using parameter PR033 Steering wheel angle, check that the steering wheel angle value is close to + 90.
If the steering wheel angle values are not correct, replace component 583 (see MR 411, Mechanical, 36A,
Steering assembly, Steering column, Removal - Refitting).

If the steering wheel is not horizontal when the vehicle is driving in a straight line (the vehicle "pulls" to the left
or right):
Check the conformity of the tyres, pressures, wear and dimensions (see MR 411, 35A, Wheels and tyres, Tyres,
