STEP 2. Using scan tool MB991958, check data list item 07:
Transfer Mode Detected.
(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 07: Transfer Mode Detected.
• Display should be the same as the actual transfer
shift lever position.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Are all position 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
.
NO : Go to Step 3.
STEP 3. Check the transfer shift lever switch.
Check for resistance between terminals for each transfer shift
lever position.
Q: Is the switch operating properly?
YES : Go to Step 4.
NO : Replace the transfer shift lever switch. Refer to
, Transmission Control.

STEP 4. Measure the switch output voltage at each
detection switch connectors C-05, C-06, C-10, C-11, C-12.
(1) Disconnect connectors C-05, C-06, C-10, C-11, C-12 and
measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 1 and ground.
• The voltage should measure between 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 10.
NO : Go to Step 5.

STEP 5. Measure the switch output voltage at transfer-ECU
connector E-104 by backprobing.
(1) Do not disconnect connector E-104.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminals 43 44, 45, 46, 47
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 8.
NO : Go to Step 6.

STEP 6. Check each detection switch connectors C-05,
C-06, C-10, C-11, C-12 and transfer-ECU connector E-104
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 7.
NO : Repair or replace the damaged components. Refer to
