NOTESSpecial notes:
Command AC013 must only be used once
Check the connection and the condition of the sensor connectors.
Disconnect the sensor, run command AC013 Test wheel speed sensor supply and check that voltage pulses of
approximately 12 V are detected by a multimeter at the sensor connector terminals on the computer side.
Are voltage pulses detected?
YES
The wiring between the computer and the sensor, as well the supply via the computer,
is OK.
Rear left-hand wheel speed sensor fault - replace the sensor.

Visually inspect the condition of the target and sensor (for dirt, metallic contamination, bearing grease, etc.),
and clean using compressed air if necessary.
If there is a lot of grease on the target, contact the Techline.
Check that the wheel speed sensor mounting is in good condition.
Check the sensor/target air gap through one wheel revolution: 0.1 mm < Rear wheel air gap < 1.2 mm.
Check the conformity of the target (condition, number of teeth = 48) using the specific command SC001 Check
target teeth.
If the checks are correct:
–the computer fault memory has been cleared,
–exit fault finding mode, switch off the ignition and carry out a road test.
–replace the rear left-hand "disc-hub-bearing" assembly (see MR 364 or MR 370 Mechanical, 33A, Rear axle
components, Bearing: Removal - Refitting) if the fault reappears.
AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

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.
