Component maintenance
The vehicle is fitted with a two-channel ABS sys-
tem, i.e. it works on both the front and the rear
wheel.
Check periodically and each time the wheels are
refitted, the tone wheel (2) or the sensor (1) re-
placed, that the wheel distance is constant at each
360°. Use a thickness gauge to check the distance
between sensor (1) and tone wheel (2) at three
points at a 120° span. The values should be be-
tween:
2.10 - 2.25 mm (0.083 - 0.088 in) for the front one;
1.90 - 2.30 mm (0.075 - 0.090 in) for the rear one;
CAUTION
IF A VALUE BEYOND THE TOLERANCE RANGE IS MEAS-
URED, REPLACE THE SENSOR (1) AND/OR THE TONE
WHEEL (2) AND REPEAT THE CHECKS; MAKE SURE
THAT THE VALUES ARE WITHIN THE TOLERANCE LIM-
ITS.
TONE WHEELS (2) CLEANING
It is important to check that all the tone wheels (2) are always clean. Otherwise,: gently remove any
possible dirt deposits with a cloth or metal brush. Avoid using solvents, abrasives and air or water jets
directly on the tone wheel (2).
TONE WHEEL SENSOR REPLACEMENT
Disconnect the tone wheel sensor connector (1) from the main wire. Unscrew and remove the screw
and remove the tone wheel sensor (1).
CAUTION
BEFORE REFITTING, MAKE SURE THAT THE FAYING SURFACES BETWEEN THE SENSOR (1)
AND THE SEAT ITSELF DO NOT SHOW SIGNS OF DAMAGE AND ARE COMPLETELY CLEAN.
ALWAYS CHECK THE DISTANCE BETWEEN THE SENSOR (1) AND THE TONE WHEEL (2).
