Parameters:
VP001: Enter VIN
This command allows the vehicle identification number to be entered into the computer.
Use this command each time the computer is replaced. The VIN (VF...) is engraved on the manufacturer's plate on
the front right-hand door pillar and stamped on the body under the windscreen on the left-hand side.
VP003: Steering wheel angle sensor
This command is used to calibrate the steering wheel angle.
With the steering wheel horizontal and the front wheels set straight ahead, calibrate the steering wheel angle sensor
using command VP003 on the diagnostic tool.
VP004: Vehicle parameters
This command configures the engine type configuration, the braking definition and the body type. Select the
command VP004 on the diagnostic tool.
VP006: Enter last After-Sales operation date
Whenever the ABS system is worked on in the shop, the date must be entered.
Select command VP006 on the diagnostic tool.
Enter the service date using the diagnostic tool keypad.
VP007: Tachometric index
This command is used to program the computer memory with the index required to calculate the vehicle speed
according to the tyre size.
The BOSCH 8.1 ESP computer supplies the vehicle speed signal to all areas where this information 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.
The tyre circumference must be programmed into the memory of a new computer. This consists of entering an index
"X" using the command VP007 "Tachometric index" on the diagnostic tool.
Once the number has been entered using the VP007 command, delete the fault in the computer memory and then
switch off the ignition. Use parameter PR030 "Tachometric index" to check that the index entered has been
recognised by the system.
VP021: Inhibit automatic brake lights
This command deactivates the automatic brake lights.
Select command VP021 on the diagnostic tool.
VP022: Automatic brake lights authorisation
This command authorises the automatic brake lights.
Select command VP022 on the diagnostic tool.
* APV: After-SalesNote:
The vehicle speed is supplied by a wire (connection 47F) to the radio, to the electric power-assisted
steering, to the electric sunroof and by the multiplex network for the other computers.
