With interface wiring disconnected from the control
unit, check the continuity between pin 23 and the
red cable of the LEFT wheel turning sensor con-
nector; the continuity between pin 17 and the
brown cables of the LEFT and RIGHT wheel turn-
ing sensors; and between pin 24 and the red cable
of the RIGHT wheel turning sensor.
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.
