STEP 6. Measure the solenoid valve output voltage at the 
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 41 and ground by 

backprobing.

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

voltage should measure battery positive voltage.

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

should measure less than 1.0 volt.

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

YES : Go to Step 9.
NO :  Go to Step 7.

STEP 7. Check joint connector A-17, free-wheel engage 
solenoid valve connectors A-38, A-39, intermediate 
connectors A-03, E-114 and transfer-ECU connector E-104 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
