STEP 2. 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 3.

STEP 3. 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 6.
NO : Go to Step 4.

STEP 4. 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 5.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 5. 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 8.
NO : Repair or replace the harness wire.
