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


caution
  • If there is any problem in the CAN bus lines, an incorrect diagnosis 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), and reset the steering wheel sensor correction amount stored in the AWC-ECU. (Item No. 1: SAS adjusted value ).

OPERATION


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

DIAGNOSIS CODE SET CONDITIONS


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

PROBABLE CAUSES



DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics.
Use M.U.T.-III to perform the CAN bus diagnosis.

Q. Is the check result normal?
Go to Step 3.
Repair the CAN bus lines. (Refer to GROUP 54C - Troubleshooting). After repairing the CAN bus line, go to Step 2.

STEP 2. Check whether the diagnosis code is set again.

STEP 4. Check whether the diagnosis code is set again.

Q. Is diagnosis code No.C2205 set?
Replace the AWC-ECU. (Refer to ). Then go to Step 5.
Intermittent malfunction. (Refer to GROUP 00 - How to Cope with Intermittent Malfunction).

STEP 5. Check whether the diagnosis code is set again.

Q. Is diagnosis code No.C2205 set?
