FAIL-SAFE FUNCTION

If an abnormality occurs to the signal of sensors, 
switches, solenoids, or others, the AWC-ECU per-
forms a control for the driver safety and system pro-
tection. The control contents are as follows.

FAIL-SAFE REFERENCE TABLE

NOTE: All the fail-safe functions are reset by turning 
OFF 

→

 ON the ignition switch.

HOW TO CONNECT THE SCAN TOOL (M.U.T.-III)

Required Special Tools:

•  MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

Diagnostic trouble code 
No.

Control content

C2203

The S-AWC control is continued with the code creation only.

C1614, C1624

A warning is given to the driver with the trouble displayed to the multi 
information display, but the S-AWC control is maintained because the vehicle 
behavior is not affected.

C1629, C1630, C1631, 
C1632, C1633, C1219, 
C2205, C121A, C1460, 
C123C, C1242, U0428, 
U0401, U1425, U1428, 
U0126, U0100

A warning is given to the driver with the trouble displayed to the multi 
information display, and the front differential control is stopped. (The center 
differential control is continued.)

C161F, C1621, C145F

A warning is given to the driver by the flashing of multi information display 
S-AWC control mode, and the S-AWC control is stopped by the protection 
control.

Others (other than above) A warning is given to the driver with the trouble displayed to the multi 

information display, and the S-AWC control is stopped.

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. Ensure that the ignition switch is at the "LOCK" (OFF) 

position.

2. Start up the personal computer.
3. Connect special tool MB991827 to special tool MB991824 

and the personal computer.

4. Connect special tool MB991910 to special tool MB991824.
5. Connect special tool MB991910 to the data link connector.
6. Turn the power switch of special tool MB991824 to the "ON" 

position.
NOTE: When special tool MB991824 is energized, special 
tool MB991824 indicator light will be illuminated in a green 
color.

7. Start the M.U.T.-III system on the personal computer.
NOTE: Disconnecting scan tool MB991958 is the reverse of the 
connecting sequence, making sure that the ignition switch is at 
the "LOCK" (OFF) position.

CHECK OF THE FREEZE FRAME DATA

Various data of when the diagnostic trouble code has been set 
is obtained, and the status of that time is stored. By analyzing 
each data using M.U.T.-III, troubleshooting can be carried out 
efficiently.
Display items of the freeze frame data are as follows.
