Code No. C2205 Internal abnormality of steering wheel sensor


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 (Refer to GROUP 54C, Trouble code diagnosis ).
  • Whenever ECU is replaced, ensure that the CAN bus lines are normal.
  • When the steering wheel sensor is replaced, always carry out calibration to make ASC-ECU learn the neutral point (Refer to ).
  • When the hydraulic unit (integrated with ASC-ECU) is replaced, always carry out the calibration of the steering wheel sensor, the G and yaw rate sensor and brake fluid pressure sensor (Refer to , and ).

OPERATION
Steering wheel sensor sends its status signal to ASC-ECU.

DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when ASC-ECU detects that the steering wheel sensor has malfunction.

PROBABLE CAUSES

  • Steering wheel sensor malfunction
  • ASC-ECU malfunction
  • External noise interference

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q. Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnosis table ). On completion, go to Step 4.

STEP 2. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.C2205 set?
Replace the steering wheel sensor (Refer to ), and then go to Step 3.
This diagnosis is complete.

STEP 3. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.C2205 set?
Replace the ASC-ECU (Refer to ), and then go to Step 4.
This diagnosis is complete.

STEP 4. Check whether the diagnosis code is reset.

Q. Is diagnosis code No.C2205 set?
Return to Step 1.
This diagnosis is complete.
