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
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.

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.

Conditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure whether the fault is present or stored.
Check the condition and connection of the battery terminals.
Check the condition and position of the ABS/ESP fuses in the engine fuse and relay box.
Check the 50A power fuse in position 5 on the power fuse board.
Check fuse F13 (25A) on the UPC and the correct locking of the grey 4-track PPH1 connector (Vdiag 44) or
the 25A fuse F8 on the UPC and the correct locking of the black 6-track CM connector (Vdiag 48).
Check the connection and condition of the tab 1 red wire of the grey connector.
Check the connections on the ABS/ESP computer 46-track connector.
Check the ABS earths on tracks 1 and 4 (mounted under the ABS/ESP unit) and visually inspect all the
ABS/ESP wiring.
Check the continuity between the fuses and tracks 2 and 3 of the computer connector (+ before ignition feed on
the tracks) and between the UCH and track 28 of the computer (+ after ignition feed on the track).
Clear the computer fault memory. Switch off the ignition.
Switch on the ignition again and carry out a new check 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.
