STEP 10. Using scan tool MB991958, check data list item
30: Free-wheel Engage Solenoid Valve.
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 the data reading mode.
• Item 30: Free-wheel Engage Solenoid Valve.
• When the transfer shift lever position is other than
2H, the display should be "ON."
• When the transfer shift lever position is 2H, the dis-
play should be "OFF."
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the solenoid valve operating properly?
YES : It can be assumed that this malfunction is intermittent.

.
CIRCUIT OPERATION
The free-wheel engage switch is turned ON when the
freewheel engage solenoid valve is activated and the
condition is shifted to the 4WD condition. The power
supply voltage is imposed to the free-wheel engage
switch from the transfer-ECU, and when the
free-wheel engage switch is turned ON, the power
supply voltage from the transfer-ECU is grounded.
.
DTC SET CONDITIONS
When the energizing condition to the free-wheel
engage solenoid valve and the condition of
free-wheel engage switch do not agree, DTC 35 is
set as the open circuit or the short circuit on the
free-wheel engage switch system.
.
TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS CODE TO BE SET ARE:)
• Malfunction of the free-wheel engage switch
• Damaged harness, connector
• Malfunction of the transfer-ECU
DIAGNOSIS
Required Special Tool:
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: V.C.I.
