Electro-magnetic electro
proportional valve magnetic
defect or shortening proportional
of BrB wiring valve or
repair BrB
wiring
Defective BrB
wiring between CNB Repair
and electro-magnetic BrB wiring
proportional valve
Defective BrB
wiring between CNB Repair BrB
and CN8 wiring.
Replace
Controller defect controller.
Replace
Solenoid valve solenoid
defect valve.
Defective wiring
between CNA and Repair
solenoid valve wiring.
Defective wiring Repair
between CN6 and CNA wiring.
Replace
Controller defect controller.
Inspect and
adjust
Throttle link system throttle
abnormality motor.
(Automatic
adjustment
necessary)
Replace
throttle

Key switch ON
When display
solenoid valve
connector is
removed, does
message go out?
When CNB connector
is removed, does
message go out?
NO
NO
NO
NO
NO
YES
For example when
swing lock no. 11 is
displayed
(Display number
explanation on
separate sheet).
When transistor
output is carried out
with self-check, are
any abnormal
points found?
When electro
magnetic
proportional valve
is removed, does
message go out?
When CN8 connector
is removed, does
message go out?
When CNA connector
is removed, does
message go out?
When CN7 connector
is removed, does
message go out?
When CN6 connector
is also removed, does
message go out?
Reconnect CN6, CN7
connectors.
Is throttle motor out of
step?
Remove throttle motor
connector, measure
resistances between B and
Br, B and R, B and O, B
and Y. (Are they within
range of 3.0~3.6 ?)
Remove throttle motor
connector. Is it continuous
between W and L on
throttle motor side?
Remove CNI and measure
resistances between male
side terminals R and B, R
and G, R and W, R and Y..
(Are they within range of
3.0~3.6 ?)
Remove CNI. Is it
continuous between
male side terminal GL
and LgR?
Does throttle motor
operate with
redundancy?
