NOTESSpecial notes:
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).
Drive in a straight line.
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,
Identification and tyre pressure, Identification).
Replace the tyre(s) if necessary (see MR 411, 35A, Wheels and tyres, Tyres, Removal - Refitting).
Adjust the wheel alignment (see MR 411, Mechanical, 30A, General information, Front axle: Adjustment).
Calibrate component 583 using command VP003 Steering wheel angle sensor (see Configurations
and programming).
Clear the ESP sensor offsets using command RZ011 Sensor offsets.

NOTESPriorities when dealing with a number of faults:
Deal with fault DF026 Front right-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.
Visually inspect the condition of the axle assemblies (impacts, deformations etc.) and the conformity and good
condition of the tyre mountings (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres, Identification
and Tyre pressure, Identification).

using compressed air if necessary.
Check that the wheel speed sensor mounting is in good condition.
Check the sensor/target air gap through one wheel revolution (0.4 < front wheel air gap < 1.7 mm).
If the air gap is incorrect:
–Replace the instrumented bearing/wheel sensor mounting assembly if necessary (see MR 411, Mechanical,
31A, Front axle components, Hub carrier bearing: Removal - Refitting).
If the air gap is correct.
–Swap both front wheel speed sensors.
–Clear the computer fault memory.
–Carry out a road test followed by another check with the diagnostic tool.
–If the fault initially declared as DF090 has become DF091 Front left-hand wheel target, replace the magnetic
target (see MR 411, Mechanical, 31A, Front axle components, Front hub carrier bearing: Removal –
Refitting).
–If the fault remains on the same side, replace component 152 (see MR 411, Mechanical, 38C, Anti-lock

NOTESSpecial notes:
Even though this is stored in the computer, this fault does not cause the warning lights
to come on or a fault message, because the ESP system is not faulty.
Perform fault finding on the UCH (Passenger compartment connection unit) using
the diagnostic tool.
Note:
After repairing the fault in the UCH (Passenger compartment connection unit),
clear the fault memory in the ESP system.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started.
Check the UCH (Passenger compartment connection unit) using the diagnostic tool (see 87B, Passenger
