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.
 
 
OPERATION
AWC-ECU receives the wheel speed data from ASC-ECU via the CAN communication.
 
 
DIAGNOSIS CODE SET CONDITION
If one or more of the wheel speed is out of the range of the specified value, the diagnosis code of the relevant wheel speed sensor is set.
 
 
PROBABLE CAUSES
  • Malfunction of wheel speed sensor
  • Damaged harness wires and connectors
  • Malfunction of encoder for wheel speed detection
  • Malfunction of ASC-ECU
  • 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 other system diagnosis code.
Check the ASC diagnosis code (Refer to GROUP 35C - Diagnosis, Diagnosis Code Chart ).
Is the diagnosis code set?
Perform the relevant troubleshooting.
Go to Step 3.
 
STEP 3. M.U.T.-IIISE data list.
Check the data list of the relevant wheel speed sensor (Refer to ).
  • Item No.35: Wheel speed (FL)
  • Item No.36: Wheel speed (FR)
  • Item No.37: Wheel speed (RL)
  • Item No.38: Wheel speed (RR)
Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
Replace the AWC-ECU (Refer to ).
