When transistor
output is carried
out with self-check,
are any abnormal
points found?
When electro

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?
