0B, 11, 12ANTI-LOCK BRAKING SYSTEM
The ESP system on this vehicle incorporates the following functions:
–The ABS (anti-lock braking system). The main functions of the ABS system are electronic front and rear braking
distribution (EBD) by controlling rear wheel slip, and preventing the wheels from locking by controlling the slipping
of all four wheels.
–MSR (engine torque control). Traction control on the driven wheels under no load by limiting the engine braking.
–ASR (traction control). It limits skidding of the drive wheels during starting or acceleration phases by limiting the
engine torque and braking the wheel(s) which are skidding.
–ESP (electronic stability program). Electronic stability program limiting oversteer or understeer by braking certain
wheels and controlling the engine torque.
–CSV (understeer control). Specific control of situations involving pronounced understeer by significant vehicle
braking in conjunction with a specific dynamic stability program.
–AUTOMATIC LIGHTING OF HAZARD WARNING LIGHTS. Generation on the CAN network, for the UCH, of a
request for switching on the hazard warning lights in case of braking causing a very hard deceleration (according
to the legislation of the country).
–AUTOMATIC BRAKE LIGHTS SWITCH-ON. In the event of understeer control (CSV only), the ESP computer
switches on the brake lights, via a relay, to give warning of severe deceleration generated by the system (according
to national legislation).
The system also supplies the other computers with information on the vehicle speed via a wire connection for the
xenon bulbs, the radio and the electric sunroof, and via the multiplex network for the other computers. The ABS/ESP
computer provides the odometry for the instrument panel and navigation aid over the multiplex network.
IDENTIFICATION
From the outside, two factors distinguish an ABS unit from an ABS/ESP unit:
–The size of the units (the ABS/ESP unit is bigger than the ABS) unit. The ABS unit has 8 solenoid valves
and the ABS/ESP unit has 12.
–The number of computer tracks (the ABS computer has 26 tracks and the ABS/ESP computer has
46 tracks).

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.

SETTINGS (continued)
VP021: Automatic brake lights deactivation.
Use this command only in those countries where legislation prohibits the brake lights lighting
automatically without the brake pedal being depressed. Brake light activation is not authorised
with ESP control (in accordance with national legislation).
VP022: Automatic brake lights authorisation.
This command is used to reactivate automatic lighting of the brake lights by ESP intervention
after it has been inhibited by command VP021 (in accordance with national legislation).
VP023: Automatic reconnection threshold of the ESP.
If the value of PR064 is not 30 mph (50 km/h), use this command to set the automatic ESP
reconnection threshold to 30 mph (50 km/h).
VP032: Vehicle speed at initialisation.
Vehicle speed transmitted via the multiplex network when the computer is initialised.
Select "Type 1" or "Type 2" according to the information supplied by the tool.

NOTESSpecial notes:
This fault does not cause the warning lights to come on or a fault message on the
instrument panel.
Check for + 12 V under + after ignition feed between tracks 1 and 5 of the brake lights on relay mounting.
If the voltage is incorrect, check the wiring harness.
Check the condition and wiring of the computer and brake lighting on relay connections.
Check and ensure the continuity of the following connections:
Relay mounting track 1Passenger compartment fuse box and relay
Relay mounting track 2 Track 22 computer connector
Relay mounting track 3Brake light connector
Relay mounting track 4 Track 30 computer connector
Also check the insulation between these connections.
If the controls are OK, check the brake lights on relay. Replace the brake lights on relay if necessary.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition, carry out a road test and then check again with the diagnostic tool.
If the fault is still present, contact the Techline.

NOTESSpecial notes:
1.DEF: This code means that the computer does not detect that the pedal is pressed
during braking (pedal pressed in relation to the pressure sensor).
2.DEF: This code means that the computer detects the pedal as pressed all the time
or that the brake light bulbs are the wrong ones.
Conditions for applying the fault finding procedure to stored faults:
Clear the stored fault, carry out a road test at a speed of > 36 mph (60 km/h) and test
the brakes with ABS regulation.
Using the diagnostic tool, check on the statuses screen that ET017 Brake pedal recognises the correct pressed
and released positions of the brake pedal.
If the correct pedal position is not displayed, use the interpretation of ET017 Brake pedal.
If the fault is still present, contact the Techline.
