In case of failures, check the continuity between
pin 23 and the connector green cable on the fuel
tank after removing the chassis central cover; be-
tween pin 17 and the yellow cables on both con-
nectors; between pin 24 and the red cable on the
connector.
With interface wiring disconnected from the control
unit and the connectors disconnected from wheel
turning sensors, check that pin 23 - 17 and 24 - 17
are insulated from each other and from earth.
With a thickness gauge, check that the air gap be-
tween the screw head and the sensor is between
0.35 and 1 mm
