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).

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.

STOREDINJECTION MULTIPLEX SIGNAL ABSENT
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 injection frame transmission fault.
Run fault finding on the injection system.
Note:
The injection does not always store these transient faults as quickly as the ABS/ESP
system. If no fault is stored in the injection computer, start the engine; if there is no fault
present, contact the Techline.
Once the fault in the injection system has been repaired, clear the ABS/ESP computer
fault memory.
The injection multiplex signal is transmitted to the ABS/ESP computer 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.
Check the condition and correct locking of the blue PEH connector of the UPC (Vdiag 44) or the grey CT1
connector of the UPC (Vdiag 48 or higher).
Carry out a multiplex network test and check the injection system 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. 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

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.
