Isuzu KB P190. Manual — part 1221
7D1-10 TRANSFER CONTROL SYSTEM
Transfer Actuator
Method of confirming the actuator position detection
(limit) switch
The actuator indicates the continuity condition of combinations,
as shown in the list below between the 4 detection (limit) switch
pins and the GND pin along the direction of the notch of the
output shaft spline. Check that these combinations are as
specified.
The middle condition between these positions (4 patterns in
the case of 2H-4H) is either of the combinations shown below,
depending upon manufacturing variations of the switch plate.

TRANSFER CONTROL SYSTEM 7D1-11
Method of checking the position detection switch harness
Disconnect the vehicle harness connector on the transfer
controller side, and the vehicle harness connector on the
transfer actuator side as shown in the wiring diagram. Check
the continuity between the following connector pins, ensure
there is no continuity between those pins and GND or power
source.
Check that there is continuity between the GND pin and the
vehicle GND on the transfer actuator, and there is no continuity
between the GND pin and another power source.
