Note:
The left and right-hand xenon bulb computers are supplied when the dipped headlights are lit. Therefore fault
finding can only be carried out on them after the ignition has been switched on in fault finding mode (forced + after
ignition feed) and the dipped headlights have been switched on.

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).

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:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. Run
fault finding on the automatic transmission with the diagnostic tool.
Note:
When the fault in the automatic transmission system is repaired, clear the ABS/ESP
fault memory.
The multiplex signal from the automatic transmission is sent to the ABS/ESP via the
Protection and Switching Unit.
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.
Using the diagnostic tool, check in the parameter screen that the PR063 "Vehicle parameters" truly correspond
with the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Check the condition and correct locking of the blue PEH connector on the UPC
(Vdiag 44) or the grey CT1 connector on the USM* (Vdiag 48).
Carry out a multiplex network test.
If the fault is still present, run fault finding on the automatic transmission gearbox and
repair as necessary.
If the fault is still present, contact the Techline.
Use command VP004 Vehicle parameters to define the appropriate parameters for the
vehicle type.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a new test with 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.

NOTESSpecial notes:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. The
ABS/ESP system is not faulty, but has received unusable signals from the automatic
transmission. Run fault finding on the automatic transmission with the diagnostic tool.
Note:
The automatic transmission does not always store these transient faults as quickly as
the ABS/ESP.
If there is no stored fault in the automatic transmission computer memory, start the
engine, and if no present fault is displayed, contact the Techline. Once the fault in the
automatic transmission 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.
Using the diagnostic tool, check in the parameter screen that the PR063 Vehicle parameters truly correspond with
the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Carry out a multiplex network test and check the automatic transmission system using
the diagnostic tool.

COMMAND (continued)
SPECIAL COMMANDSAC195:Vehicle speed signal.
This command sends a speed other than 0 mph on the computer's vehicle speed wire output
(Track 33) to users of that signal (xenon bulbs, radio, sunroof).
Note:
This command has no visible effect on the dashboard speedometer needle.
Xenon bulbs: Switch on the dipped headlights and run command AC195. You should see a slight
change in the height of the headlight beam (depending on vehicle speed, the height of the beam is
adjusted to improve visibility).
–Radio: switch on the radio and check that the speed-dependent volume control function is active.
Run command AC195. During the command, you should notice the volume of the sound increase
and then decrease.
–Sunroof: this command has no visible effect on the sunroof. This command changes the activation
threshold of the anti-pinch system (the pressure exerted by the sunroof varies with vehicle speed
due to aerodynamic factors).
AC196:Request to switch on hazard warning lights.
This command sends the UCH a request to switch on the hazard warning lights to test their operation
during emergency braking (depending on UCH configuration).
SC001: Check target teeth.
This command tests the condition of the teeth on each wheel. Select command SC001 Test target
teeth. The test result should show 48 teeth.
SC006: Bleed the hydraulic unit and brake circuits.
Use this command if abnormally long brake pedal travel is noted during a road test with ABS control
(the system must have been bled beforehand by the usual procedure).
Select the SC006 "Bleed hydraulic unit and brake circuit" command and follow the instructions
given by the diagnostic tool.
