PRECAUTIONS FOR DIAGNOSIS

Before diagnosis, check that all the following items 
are normal.

• A normal steering wheel is installed correctly to 

the neutral position of steering column shaft 
assembly.

• The size of tire and wheel, specification, tire pres-

sure, balance, and wear status are normal.

• The wheel alignment is normal.
• No modifications to the engine, suspension, or 

others, which can affect the S-AWC system, is 
implemented.

DIAGNOSTIC FUNCTION

M1221007700078

WARNING INDICATOR

When a malfunction occurs in the S-AWC system, the figure (A) 
will be displayed on the information screen of multi information 
display, and the mode display (B) will be turned off.
Subsequently, the screen returns to the one before the warning 
display, and then "!" indicator (C) will illuminate.
If the indicator (C) continues to be displayed on the information 
screen of multi information display, check the diagnostic trouble 
code that is set.

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 troubles will return to a normal status
