Code No. C2204 Sensor Cluster 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 (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
  • Whenever ECU is replaced, ensure that the CAN bus lines are normal.
 
 
OPERATION
The ASC-ECU communicates with its integrated G and yaw rate sensor.
 
 
 
DIAGNOSIS CODE SET CONDITION
This diagnosis code will be set when the ASC-ECU detects an defective G and yaw rate sensor.
noteThis diagnosis code may be set when G and yaw rate sensor is put on the turntable turning at high speed.
 
 
 
PROBABLE CAUSE
  • ASC-ECU malfunction
 
 
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnosis
Use M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 3.
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ). On completion, go to Step 2.
 
STEP 2. Diagnosis code recheck after resetting CAN bus lines
Is diagnosis code No.C2204 set?
Go to Step 3.
This diagnosis is complete.
 
STEP 3. Check whether the ASC-ECU is installed properly.
Check whether the ASC-ECU is installed correctly. Refer to .
Is the check result normal?
Go to Step 4.
Repair it.
 
STEP 4. M.U.T.-IIISE data list
Check the following data list (Refer to ).
  • Item 06: Yaw rate sensor
  • Item 08: Lateral G sensor
  • Item 18: Yaw rate sensor offset
  • Item 20: Lateral G sensor offset
Is the check result normal?
Go to Step 5.
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
 
STEP 5. Check whether the diagnosis code is set again.
(1) Erase the diagnosis code.
(2) Turn the steering wheel to either right or left at 20 km/h or more.
noteThe ASC warning/operation lamp and the ASC OFF lamp may remain on until the vehicle speed reaches approx. 10 km/h, then the steering wheel is turned to either right or left.
Is diagnosis code No.2204 set?
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How to Cope with Intermittent Malfunctions ).
