Settings
VP001: Write 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 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 (it is imperative to check that the variants selected
correspond to the vehicle type).
VP006: Write date of the last After-Sales service.
Whenever the ABS system is worked on in the shop, the date must be entered.
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 ABS 8.0 computer supplies the vehicle speed signal to all vehicle systems that use this
information (instrument panel, engine management, etc.). This vehicle speed signal replaces the one
supplied by the speed sensor located on the gearbox. The ABS computer calculates the vehicle speed
from the speed of the wheels and the circumference of the tyres fitted on the vehicle.
Note:
The vehicle speed is sent by wire (track 23) to the xenon bulb computer, radio and electric sunroof, and
via the multiplex network to the other computers.
The tyre circumference must be programmed into the memory of a new computer. This consists
of entering a number X using the VP007 "Tachometric index" command 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 the parameter PR030 to check that the index entered has been
stored correctly.
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.

1.DEF : Carry out the multiplex network fault finding procedure
NOTESSpecial notes:
Although stored in the computer, the fault is not due to ABS components but injection
components. Run fault finding on the injection system.
Note:
The injection computer does not always store these transient faults as quickly as the
ABS computer. If no fault is stored in the injection computer, start the engine; if there
is no fault present, contact the Techline. After solving the injection system problem,
erase the faults from the ABS computer memory.
The multiplex injection signal is sent to the ABS system 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 on the UPC (Vdiag 44) or the grey CT1
connector of the UPC (Vdiag 48).
Carry out a multiplex network test and check the injection system with the diagnostic tool.
If the fault is still present, contact the Techline.

ALP1 No dialogue with the ABS computer
NOTESSpecial notes:
To run fault finding on the vehicle's computers, switch on the ignition in fault
finding mode (forced + after ignition feed). Proceed as follows:
–with the vehicle card in the card reader, press the Start button for more than
5 seconds outside of starting conditions.
Check that the CLIP diagnostic tool is equipped with the latest update available.
Check that the diagnostic tool is not causing the fault by trying to establish dialogue with a computer on another
vehicle. If the tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle,
the cause could be a faulty computer interfering on the multiplex network. Check the battery voltage and carry out
the necessary work to obtain the correct voltage (9.5 V < battery voltage < 17.5 V).
Carry out a fault finding procedure on the multiplex network using the diagnostic tool.
Check the presence and the condition of the ABS fuses on the passenger compartment fuse board and in the
engine fuse box. Check that the computer connector is properly connected and check the condition of its
connections. Check the ABS earths (good condition, not corroded, tightness of the earth screw above the ABS
assembly). Check that the supply to the computer is correct:
–Earth on tracks 1 and 4 of the 26-track connector.
–+ before ignition feed on tracks 2 and 3 of the 26-track connector.
–+ after ignition feed on track 18 of the 26-track connector.
Check that the power supply to the diagnostic socket is correct:
–+ before ignition feed on track 16.
–+ after ignition feed on track 1.
–Earth on tracks 4 and 5.
If dialogue has still not been established after these checks, contact the Techline.
AFTER REPAIRClear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESOnly consult this customer complaint after a complete check with the diagnostic tool.
Disconnect one wheel speed sensor. Start the
engine and ensure that only the ABS fault warning
light comes on. Do not drive the vehicle if the brake
fault warning light is also lit, as the brake limiter
function is no longer guaranteed to operate correctly.
Carry out a road test with the ABS thus out of order.
Is the fault still present under these conditions?
NO
Raise the vehicle so that you can rotate the wheels
and check:
Possible inversion when connecting the speed
sensors.
Possible inversion of pipes on the hydraulic unit.
To perform these tests, refer to and apply the
procedures defined in ALP2. Check the condition
and conformity of the ABS targets. Also check the
sensor/target air gap by rotating each front and rear
wheel one revolution. If the fault is still present,
contact the Techline.
YESIf the brake pedal travel is relatively long,
bleed the brake circuit. If the travel is
normal, check the tyre pressures, the
front axle, or for any leaks in the circuit.
AFTER REPAIRClear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
