STEP 7. Measure the switch output voltage at transfer-ECU 
connector E-104 by backprobing.
(1) Do not disconnect connector E-104.
(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.

(4) Measure the voltage between terminal 50 and ground by 

backprobing.

• When the transfer shift lever position is 2H, voltage 

should measure 10.5 volts.

• When the transfer shift lever position is other than 2H, 

voltage should measure 0 volt.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage within the specified range?

YES : Go to Step 10.
NO :  Go to Step 8.
