Diagnostics - Replacing parts
REPLACING THE COMPUTER
When replacing the computer (see MR411 Mechanical systems, 38C, Brake computer, removal - refitting), apply
the following procedure:
–switch off the ignition,
–replace the computer,
–enter the VIN number using command VP001 "Write VIN",
–configure the tachometric index with command VP007 "Tachometric index",
–configure the vehicle parameters with command VP004 "Vehicle parameters",
–configure the gearbox type fitted to the vehicle with command CF079 "Gearbox type",
–enter the After-Sales date with command VP006 "Enter last After-Sales operation date",
–perform a road test followed by a fault reading to confirm that the system is operating correctly.

Diagnostics - Configuration and Programming
SETTINGS
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.
VP004: Vehicle parameters.
This command configures the engine type configuration, the braking definition and the body type.
Select command VP004 on the diagnostic tool.
VP006: Write last After Sales operation date.
Whenever the ABS system is worked on in the shop, the date must be entered.
Select command VP006 "Write date of last After-Sales operation" 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 MK70 ABS 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 ABS computer calculates the vehicle speed from the speed of the wheels and the circumference of the
tyres fitted on the vehicle.
The tyre circumference must be programmed into the memory of a new computer. This consists of entering
an index "X" using 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 correctly
registered.
CONFIGURATIONS
CF079: Gearbox type.
Use this command to configure the gearbox type fitted on the vehicle.
OTHER COMMANDS
LC008: Gearbox type.
This command tells you the gearbox type configured on the vehicle. Note:
The vehicle speed is delivered by 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.

TACHOMETRIC INDEX PROGRAMMING
1.DEF: Tachometric index not programmed
NOTESNone
The MK70 ABS computer with the tachometric function 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 ABS computer calculates the vehicle speed from the speed of the wheels and the circumference of the tyres
fitted on the vehicle.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering an index "X" using command VP007 "TACHOMETRIC INDEX" using the diagnostic tool.
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.
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.

GEARBOX TYPE CONFIGURATION
DEF: Configuration absent or incorrect
NOTESPriorities when dealing with a number of faults:
Deal with fault DF097 No automatic transmission multiplex signal first if it is
present.
Check the gearbox type configuration with the diagnostic tool, using command LC008 Gearbox type.
If the configuration is not correct, configure the gearbox type present on the vehicle using command CF079
Gearbox type.
Clear the computer fault memory, exit the fault finding and 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.

OR
STOREDNO BVR MULTIPLEX SIGNAL
NOTESSpecial notes:
Even though it is stored in the computer, this fault does not cause the warning lights to
come on or a fault message, because the ABS system is not faulty.
Perform fault finding on the BVR (sequential gearbox) using the diagnostic tool.
Note:
After repairing the fault in the BVR (sequential gearbox), clear the fault memory
in the ABS system.
Priority in the event of a number of faults:
Deal with fault DF152 Multiplex network first if it is 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 gearbox type configuration with the diagnostic tool, using command LC008 Gearbox type.
If the configuration is not correct, configure the gearbox type present on the vehicle using configuration command
CF079 Gearbox type.
Check the BVR (sequential gearbox) using the diagnostic tool.
Run a multiplex network test (see 88B, Multiplex).
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.
