STOREDSTEERING WHEEL ANGLE PROGRAMMING OFFSET
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after an extended road test.
With the steering wheel horizontal and the wheels set straight ahead (the wheels must be directly in line with the
vehicle), read the value of the steering wheel angle using 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 offsets.
With the steering wheel horizontal and the 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 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 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 straight ahead (the vehicle "pulls" to the left or
right).
Check the conformity of the tyres, pressures, wear, and dimensions (see MR 411, Mechanical, 35A, Wheels and
tyres, Tyres: Identification and Tyre pressure, Identification).
Replace the tyre(s) if necessary (see MR 411, Mechanical, 35A, Wheels and tyres, Tyres, Removal -
Refitting).
Adjust the wheel alignment (see MR 411, Mechanical, 30A, General information, Front axle: Adjustment).
With the steering wheel horizontal and the wheels set straight ahead, calibrate component 583 using command
VP003 Steering wheel angle sensor.
Clear the ESP sensor offsets using command RZ011 Sensor offsets.

ALP2 Locking or braking of one or more wheels
NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check the conformity of the mechanical components (see MR 411, Mechanical,
30A, General information, Brake, Specifications).
REMINDERLocking of wheels on a vehicle fitted with ABS or squealing of the tyres, which feels like
locking to the customer, may be linked to normal operation of the system and should not
always be considered a fault.
Braking with ABS regulation on very poor roads can cause significant squealing.
However, if the wheel(s) is/are actually locking, lift the vehicle in order to be able to rotate the wheels and check:
Possible inversion when connecting the speed sensors.
Use parameters PR001 Front right-hand wheel speed, PR002 Front left-hand wheel speed, PR003 Rear right-
hand wheel speed and PR004 Rear left-hand wheel speed whilst slowly turning the wheels in question and
checking 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.
If a single reading is incorrect:
–Check that the sensor casing is secured when rotating.
–Check that the wheel speed sensor mounting is in good condition.
–If that is unsuccessful, replace the corresponding sensor and repeat the check procedure (see MR 411
Mechanical, 38C, Anti-lock braking system, Wheel speed sensor: Removal - Refitting).
–A possible inversion of the pipes on the hydraulic unit (see MR 411, Mechanical, 38C, Anti-lock braking
system, Hydraulic braking unit, List and location of components).
Run 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 locking/unlocking cycles on the wheel concerned (see Dealing with
command modes).
If the cycles are not detected on the wheel tested (wheel remains locked), check if they occur on another wheel
(confirmation of a reversal after a repair, see MR 411, Mechanical, 38C, Hydraulic braking unit, List and
location of components).
If the cycles are not detected on a wheel and the pipes have not been inverted, replace component 1094
(see MR 411, Mechanical, 38C, Hydraulic braking unit, Removal- Refitting).
Check that the sensor holder does not rotate (depending on fitting).
Check the quality of the mounting of the wheel speed sensors (correct clipping for the front wheels).
Check the conformity of the targets: the condition and the number of teeth= 48 (using the command SC001
"Check target teeth").
Replace if necessary.
If the fault is still present after these checks, replace component 1094 (see MR 411, Mechanical, 38C, Hydraulic
braking unit, Removal- Refitting).
