Code No. C1630: Steering Wheel Sensor CAN Data (not received)
 
 
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: Steering angle 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 CAN signal of the steering wheel sensor cannot be received.
 
 
PROBABLE CAUSES
  • Malfunction of the CAN bus line
  • Damaged connectors (steering wheel sensor)
  • Malfunction of the steering wheel sensor
  • Malfunction of AWC-ECU

 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics.
Use M.U.T.-IIISE to perform the CAN bus diagnosis.
Is the check result normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE data list.
Check the following data list (Refer to ).
Item No.21: Steering angle
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
Replace the steering wheel sensor (Refer to GROUP 35C - Steering Wheel Sensor ). Then go to Step 3.
 
STEP 3. Check whether the diagnosis code is set again.
Is diagnosis code No.C1630 set?
Replace the AWC-ECU (Refer to ).
This diagnosis is complete.
