.

STEP 5. Check harness for open circuit or short circuit to 
ground between junction block connector D-208 terminal 2 
and transfer shift lever switch connector E-116 terminal 1.
Q: Is the harness wire in good condition?

YES : Go to Step 10.

STEP 6. Measure the switch output voltage at transfer-ECU 
connector E-109 by backprobing.
(1) Disconnect connector E-109 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 20 (Transfer shift 

lever position: 2H) and ground by backprobing. [terminal 21 
(Transfer shift lever position: 4H), terminal 22 (Transfer shift 
lever position: 4HLc), terminal 23 (Transfer shift lever 
position: 4LLc) and ground by backprobing.]

• The voltage should measure battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

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

STEP 7. Check transfer-ECU connector E-109 and transfer 
shift lever switch connector E-116 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 8.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection
