This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.

–connect the diagnostic tool and perform the required operations.
To cut off + after ignition feed, proceed as follows:
–disconnect the diagnostic tool,
–press the Start button twice briefly (less than 3 seconds),

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.

Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors for these lines (for oxidation, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaint.
A synopsis of the general procedure to follow is provided on the following page in
the form of a flow chart.

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.

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).
