If pulses are detected, the rear left-hand wheel speed sensor is defective, replace the
sensor.
NOCheck the connection and condition of the connections of the ABS computer,
component code 118.
If the connector is faulty and there is a repair method (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for repair), repair the connector,
otherwise replace the wiring.
Check and ensure the continuity of the following connections:
–4G between components 151 and 118,
–4H between components 151 and 118.
Also check the insulation between these two connections.
If the connection or connections are faulty and if there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

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 conformity of the target (condition, number of teeth = 48 or 44 depending on the version) with the specific
command SC001 Check target teeth.
If the checks are correct:
– clear the computer fault memory using the command RZ001 Fault memory,
– exit fault finding mode, switch off the ignition and carry out a road test.
Replace the instrumented bearing if the fault recurs.
If the fault is still present, contact the Techline.

PRESENTTACHOMETRIC INDEX PROGRAMMING
NOTESNone.
The ABS BOSCH 8.1 computer with "tachometric function" must have an index value in order to calculate the
vehicle speed from the speed at which the tyres turn.
Use command VP007 Tachometric index and check that it has been taken into account using parameter PR030
Tachometric index.
IMPORTANT:
The vehicle speed information is not delivered to the other computers by the ABS computer.
The vehicle speed signal is delivered by a speed sensor located on the gearbox, which informs the
computers (instrument panel, engine management, etc.).
If the fault is still present, contact the Techline.
