TACHOMETRIC INDEX PROGRAMMING
NOTESSpecial notes: ABS warning light flashing at 8 Hz out of fault finding mode.
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 X index using the diagnostic tool and the command VP007 Tachometric index.
Once the index has been entered using command VP007 Tachometric index, clear the computer fault memory
and then switch off the ignition. Use parameter PR030 Tachometric index to check that the index entered is being
used correctly by the system.
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.

STOREDNO AUTOMATIC TRANSMISSION MULTIPLEX SIGNAL
Vdiag: 0A, 0B, 11, 12
NOTESSpecial notes:
Although it is stored in the computer, this fault does not cause the warning lights to
come on or generate a fault message, because the ABS/ESP system is not faulty. Run
fault finding on the automatic transmission with the diagnostic tool.
Note:
When the fault in the automatic transmission system is repaired, clear the ABS/ESP
fault memory.
The multiplex signal from the automatic transmission is sent to the ABS/ESP 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.
Using the diagnostic tool, check in the parameter screen that the PR063 "Vehicle parameters" truly correspond
with the vehicle undergoing fault finding.
Is PR063 Vehicle Parameters correct?
YES
Check the condition and correct locking of the blue PEH connector on the UPC
(Vdiag 44) or the grey CT1 connector on the USM* (Vdiag 48).
Carry out a multiplex network test.
If the fault is still present, run fault finding on the automatic transmission gearbox and
repair as necessary.
If the fault is still present, contact the Techline.
Use command VP004 Vehicle parameters to define the appropriate parameters for the
vehicle type.
Clear the computer fault memory.
Exit fault finding mode, switch off the ignition and carry out a new test with 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.

Even though it is stored in the computer, this fault does not cause the warning lights to
come on or a fault message. Using the diagnostic tool, run fault finding on the

Note:
Once the fault in the instrument panel system has been remedied, clear the ABS/ESP
computer fault memory.
The multiplex signal from the instrument panel is sent to the ABS/ESP 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.

Relay mounting track 1Passenger compartment fuse box and relay
Relay mounting track 2 Track 22 computer connector
Relay mounting track 3Brake light connector
Relay mounting track 4 Track 30 computer connector
Also check the insulation between these connections.
If the controls are OK, check the brake lights on relay. Replace the brake lights on relay if necessary.

NOTESSpecial notes:
1.DEF: This code means that the computer does not detect that the pedal is pressed
during braking (pedal pressed in relation to the pressure sensor).
2.DEF: This code means that the computer detects the pedal as pressed all the time
or that the brake light bulbs are the wrong ones.
Conditions for applying the fault finding procedure to stored faults:
