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
VP001: Write VIN.
This command permits manual entry of the vehicle's VIN into the computer. Use this command
each time the computer is replaced. The VIN number (VF...) can be found on the manufacturer's
plate on the front right-hand door pillar and on the body panel under the left-hand side of the
windscreen.
VP004: Vehicle parameters.
This command is used to configure the engine type + braking definition + body type.
Select command VP004 on the diagnostic tool (the parameters selected must correspond with
the vehicle type).
VP006: Write last After-Sales operation date.
The date of the operation must be entered whenever the ESP system is worked on in the
workshop. Select command VP006 on the diagnostic tool.
Enter the operation date with the tool keyboard.
VP007: Tachometric index.
This command is used to program the computer memory with the index required to calculate
vehicle speed from the speed at which the wheels turn.
The Bosch 8.0 ESP computer transmits the vehicle speed signal to all areas where this signal is
needed (instrument panel, engine management, etc.). This vehicle speed signal replaces the one
supplied by the speed sensor located on the gearbox.
The ESP computer calculates the vehicle speed from the wheel speed and the tyre
circumference.
Note:
The vehicle speed is conveyed by wire (track 33) to the xenon bulbs, radio and electric sunroof,
and by the multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists
of entering an index X using the diagnostic tool and command VP007 Tachometric index.
Once the index has been entered using the VP007 command, clear the computer fault memory
and then switch off the ignition. Use the PR030 parameter to check that the index has been stored
correctly.

NOTESSpecial notes: ABS warning light flashing at 8 Hz out of fault finding mode.
The Bosch 8.0 ESP computer transmits the vehicle speed signal to all areas where this signal is needed
(instrument panel, engine management, etc.).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox. The ESP
computer calculates the vehicle speed from the wheel speed and the tyre circumference.
Note:
The vehicle speed is conveyed by wire (track 33) to the xenon bulbs, radio and electric sunroof, and by the
multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering an X index using the diagnostic tool and the command VP007 Tachometric index.
Once the index has been entered using command VP007 Tachometric index, clear the computer fault memory
and then switch off the ignition. Use parameter PR030 Tachometric index to check that the index entered is being
used correctly by the system.
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.

1.DEF : inconsistency
2.DEF : permanent high signal
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.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with 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.
