28 Control panel fault
. The
RHL control lever (7) (Fig
.
D -37) faulty.
Check the reliability of connection of the connectors
of the control panel and electronic unit as well as
check the bundle for mechanical damage. Check the
output voltage according to the electric diagram.
31 The right-
hand force sensor
is faulty. Cable breakage or
shirt circuit in the sensor
(Fig. D -37)
Check the connection of the cable to the force sensor
and check the cable for mechanical damage. Over-
load of the force sensor is also possible.
