STEP 10. Using scan tool MB991502, check data list item
06: Transfer Shift Lever Position.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991502 to data reading mode for item 06,
Transfer Shift Lever Position.
• Display should be the same as the actual transfer shift
lever position.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is switch operating properly?
YES : If 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 : Replace the transfer-ECU.

.
CIRCUIT OPERATION
• A battery positive voltage is applied to the each
detection switch (terminal 1) from the transfer-
ECU (terminal 43, 44, 45, 46 or 47).
• The each detection switch is grounded through
the transfer case to the vehicle body.
.
DTC SET CONDITIONS
In the case that the transfer shifting has not been
completed during driving, the DTC 32 is set as the
open circuit or the short circuit of each transfer
detection switch system, malfunction of the shift
actuator or the malfunction of the transfer shift mech-
anism. In the case that the input signal from each
transfer detection switch is unstable, the DTC 33 is
set as the open circuit or the short circuit of each
transfer detection switch system.
.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)
• Malfunction of the each transfer detection switch
• Damaged harness, connector
• Malfunction of the transfer-ECU
• Malfunction of the shift actuator
• Malfunction of the transfer shift mechanism

DIAGNOSIS
Required Special Tool:
• MB991502: Scan Tool (MUT-II)
STEP 1. Using scan tool MB991502, check actuator test
item 02 or 03: Shift Actuator <Only when DTC 32 is set>.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 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 MB991502 to actuator testing mode for item
02 or 03, Shift Actuator.
• The shift actuator operate.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the shift actuator operate?
YES : Go to Step 2.
NO : Replace the shift actuator. Refer to GROUP 23B,
Transfer
.
STEP 2. Using scan tool MB991502, check data list item 07:
Transfer Mode Detected.
(1) Connect scan tool MB991502 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 MB991502 to data reading mode for 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.
