4WD Controller and ITS Circuit Check
VOLTAGE CHECK
Check for input or output voltage of 4WD controller (1) (voltage
between each circuit and body ground) with 4WD controller con-
nector connected and ignition switch turned START (engine run).
* : With engine runningCAUTION:
Disable air bag system (if equipped with Air Bag), refer
to “Disabling Air Bag System” in Section 10B.
This check must be carried out in a well-ventilated
place.
