23A-507

STEP 3. Measure the power supply voltage at shift actuator 
connector C-09.
(1) Disconnect connector C-09 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.

(4) Measure the voltage between terminal 2 and ground.

• When the operating transfer shift lever 2H → 4H, 4H → 

4HLc or 4HLc 

→ 4LLc, the voltage should measure bat-

tery positive voltage.

(5) Measure the voltage between terminal 1 and ground.

• When the operating transfer shift lever 4LLc → 4HLc, 

4HLc 

→ 4H or 4H → 2H, the voltage should measure 

battery positive voltage.

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

YES : Replace the shift actuator. Refer to GROUP 23B, 

Transfer 

P.23B-75

.

NO :  Go to Step 4.

STEP 4. Measure the actuator output voltage at 
transfer-ECU connector E-109 by backprobing.
(1) Do not disconnect connector E-109.
(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.

(4) Measure the voltage between terminal 1 and ground by 

backprobing.

• When the operating transfer shift lever 2H → 4H, 4H → 

4HLc or 4HLc 

→ 4LLc, the voltage should measure 1/2 

battery voltage 

→ battery positive voltage → 1.0 volt or 

less 

→ 1/2 battery voltage.

• When the operating transfer shift lever 4LLc → 4HLc, 

4HLc 

→ 4H or 4H → 2H, the voltage should measure 

1/2 battery voltage 

→ 1.0 volt or less → 1/2 battery volt-

age.

(5) Measure the voltage between terminal 3 and ground by 

backprobing.

• When the operating transfer shift lever 2H → 4H, 4H → 

4HLc or 4HLc 

→ 4LLc, the voltage should measure 1/2 

battery voltage 

→ 1.0 volt or less → 1/2 battery voltage.

• When the operating transfer shift lever 4LLc → 4HLc, 

4HLc 

→ 4H or 4H → 2H, the voltage should measure 

1/2 battery voltage 

→ battery positive voltage → 1.0 volt 

or less 

→ 1/2 battery voltage.

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

YES : Go to Step 7.
NO :  Go to Step 5.

STEP 5. Check shift actuator connector C-09 and 
transfer-ECU connector E-109 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 6.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

.

STEP 6. Check harnesses for short circuit to ground 
between shift actuator connector C-09 terminals 2, 1 and 
transfer-ECU connector E-109 terminals 1, 3.
Q: Are the harnesses wire in good condition?

YES : Go to Step 9.
