REPLACING THE COMPUTER
When replacing the computer/pump assembly, follow this procedure:
–switch off the ignition,
–replace the computer (see MR 364 Mechanical or MR 370 Mechanical, 38C, Anti-lock braking system,
Hydraulic unit),
–enter the VIN using command VP001,
–configure the tachometric index using command VP007,
–configure the vehicle parameters with command VP004.
If Vdiag 0B, 11 or 12:
–configure the vehicle speed at initialisation with command VP032,
–inhibit or authorise the automatic brake light illumination (depending on the country's legislation)
using commands VP021 "Inhibit automatic brake light illumination" or VP022 "Authorise automatic
brake light illumination",
–enter the most recent After Sales operation date using command VP006,
–perform a road test followed by a fault reading to confirm that the system is operating correctly.
REPLACING THE COMBINED SENSOR
When replacing the combined sensor, you must erase the programming of the ESP sensors with command RZ003 (if
available).
Command RZ003 "Programming ESP sensors" is only available on Vdiag 09, 0A, 0B, 11, 12. IMPORTANT
It is imperative to check that the parameters selected match the vehicle's description.
Note:
Run this command every time the electric power steering is removed and refitted, and each time the steering wheel
angle is calibrated in the electric power steering subgroup.

STOREDCOMBINED SENSOR SIGNAL PLAUSIBILITY
NOTESSpecial notes:
This fault means that the combined sensor signals are not consistent with the other
ESP sensors (steering wheel angle sensor and wheel speed sensors). If the fault
appears while the vehicle is being driven on a steep gradient, during a very tight turn
or while the vehicle is being transported on a lorry, train, boat, etc., with the engine
running, clear the fault and if possible check that the fault has disappeared by carrying
out a road test.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present during a road test.
Check the connection and condition of the combined sensor connector.
Ensure that the sensor is properly fixed to the body in the right direction (arrow pointing to the front of the vehicle).
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of the
tyres.
Using the diagnostic tool, calibrate the steering wheel angle in the "Electric power steering" subgroup followed by
command RZ003 "ESP sensor programming" for Vdiag 09, 0A, 0B, 12 and 11 in the ABS/ESP.
Re-establish dialogue with the ABS/ESP computer, clear the computer fault memory, carry out a road test then
check again with the diagnostic tool.
If the fault is still present, adjust the axle assembly geometries. Adjust if necessary and use the diagnostic tool to
calibrate the steering wheel angle again in the "Electric power steering" subgroup, then run command RZ003 ESP
sensor programming for Vdiag 09, 0A, 0B, 12 and 11 in the ABS/ESP.
Carry out a road test.
If the fault is still present, replace the sensor.
AFTER REPAIRClear the computer fault memory. If the combined sensor has been replaced, erase the
ESP sensor programming (Vdiag 09, 0A, 0B and 11) with command RZ003 ESP
sensor programming.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Although it is stored in the computer, the ABS/ESP system is not faulty. The ESP is
deactivated due to unusable information from the electric power steering system. Run
fault finding on the electric power steering with the diagnostic tool.
Note:
The electric power steering does not always store these transient faults as quickly as
the ABS/ESP system.
If no fault is stored in the electric power steering computer memory, start the engine; if
no present fault is displayed, contact the Techline. Once the fault in the electric power
steering system has been repaired, clear the ABS/ESP computer fault memory.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after starting the engine.
1.DEF
NOTESNone
Check the condition of the axle assemblies (impacts, damage, etc.) and the conformity and good condition of
the tyres.
Check the axle assemblies, adjust if necessary.
Calibrate the steering wheel angle in the electric power-assisted steering using the diagnostic tool.
Ensure that the combined sensor is properly fixed to the body in the right direction (arrow towards the front of
the vehicle).
If all the checks are OK, clear the computer fault memory and clear the ESP sensor programming (Vdiag 09, 0A,
0B, 12 and 11) using command RZ003 "ESP sensor programming".
Carry out a road test.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Although the fault is stored in the computer, it is not caused by ABS/ESP components,
but it indicates that the ESP is deactivated due to an electric power steering frame
transmission fault. Run fault finding on the electric power steering.
Note:
The electric power steering does not always store these transient faults as quickly as
the ABS/ESP system.
If there is no stored fault in the electric power steering computer memory, start the
engine; if no present fault is displayed, contact the Techline. Once the fault in the
electric power steering system has been repaired, clear the ABS/ESP computer fault
memory.
Priorities when dealing with a number of faults:
Deal with faults DF152 and DF153 first, whether they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is started up.
Check the condition and correct locking of the blue PEH connector on the UPC (Vdiag 44) or the grey CT1
connector on the UPC (Vdiag 48).
Carry out a multiplex network test and check the electric power steering system using the diagnostic tool. 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.
