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?

STEP 8. Using scan tool MB991958, check data list item 10:
Shift Actuator Amperage.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.
(4) Set scan tool MB991958 to data reading mode.

• Item 10: Shift Actuator Amperage.

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

→ 4HLc or 4HLc → 4LLc, the display should be 0

ampere

→ 0.2 − 1.5 ampere → 0 ampere.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the actuator operating properly?

YES : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points

− How to

Cope with Intermittent Malfunction

P.00-6

.

NO : Replace the transfer-ECU.

DTC 44: Shift Actuator System (Overload)

.

SHIFT ACTUATOR SYSTEM CIRCUIT
Refer to

P.23A-492

.

.

CIRCUIT OPERATION
Refer to

P.23A-492

.

.

DTC SET CONDITIONS
When the accumulated time to operate the shift actu-
ator exceeds five minutes, DTC 44 is set as the over-
load of the shift actuator.

.

TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS CODE TO BE SET ARE:)

• Malfunction of the shift actuator

• Damaged harness, connector

• Malfunction of the transfer-ECU

DIAGNOSIS

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

STEP 1. Using scan tool MB991958, check actuator test
item 02 or 03: Shift Actuator.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.
(4) Set scan tool MB991958 to actuator testing mode.

• Item 02, 03: Shift Actuator.

• The shift actuator operate.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the actuator operating properly?

YES : It can be assumed that this malfunction is intermittent.

.

NO : Go to Step 2.

STEP 2. Using scan tool MB991958, check data list item 12:
Shift Actuator Voltage.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Transmission range should be "N" range.
(4) Set scan tool MB991958 to data reading mode.

• Item 12: Shift Actuator Voltage.

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

→ 4HLc or 4HLc → 4LLc, the display should be 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 display should

be 1/2 battery voltage

→ 1.0 volt or less → 1/2 bat-

tery voltage.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the actuator operating properly?

YES : It can be assumed that this malfunction is intermittent.
