CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

OPERATION

AWC-ECU receives chassis number information 
from the ECM. 

.

DIAGNOSTIC TROUBLE CODE SET 
CONDITIONS

This diagnostic trouble code is set when the chassis 
number is not written to the AWC-ECU.

.

PROBABLE CAUSES

• Malfunction of the CAN bus line

• Chassis number not written

• Malfunction of ECM

• Malfunction of AWC-ECU

• ETACS-ECU malfunction

Code No.C2205: Steering Wheel Sensor System (Internal Error)

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

• When the steering wheel sensor is replaced, 

calibrate the steering wheel sensor (Refer to 
GROUP 35C 

 On-vehicle Service 

P.35C-283

), 

and reset the steering wheel sensor correc-
tion amount stored in the AWC-ECU. (Item No. 
1: SAS adjusted value 

P.23C-256

).

.

OPERATION

AWC-ECU communicates with the steering wheel 
sensor via the CAN bus lines.

.

DIAGNOSTIC TROUBLE CODE SET 
CONDITIONS

This diagnostic trouble code is set when the 
AWC-ECU receives the failure status information by 
the self-diagnosis of the steering wheel sensor.

.

PROBABLE CAUSES

• Malfunction of the steering wheel sensor

• Malfunction of AWC-ECU
