    Q: Is the check result satisfactory? 

    1. YES:  Go to Step 2.
    2. NO:  Repair the CAN bus lines (Refer to CAN BUS DIAGNOSTIC TABLE ). Then go to  Step 9.
  2. STEP 2. Check the MFI system diagnostic trouble code. 

    Using scan tool (M.U.T.-III), perform MFI system diagnostic trouble code (Refer to DIAGNOSIS FUNCTION < 2.4L ENGINE >, DIAGNOSIS FUNCTION < 3.0L ENGINE >).

    Q: Is any diagnostic trouble code stored? 

    1. YES:  Repair the MFI system (Refer to DIAGNOSTIC TROUBLE CODE CHART < 2.4L ENGINE >, DIAGNOSTIC TROUBLE CODE CHART < 3.0L ENGINE >). Then go to  Step 9.
    2. NO:  Go to Step 3.
  3. STEP 3. Check the transaxle system diagnostic trouble code. 

    Using scan tool (M.U.T.-III), perform transaxle system diagnostic trouble code (Refer to DIAGNOSIS FUNCTION < CVT >, DIAGNOSIS FUNCTION < A/T >).

    Q: Is any diagnostic trouble code stored? 

    1. YES:  Repair the transaxle system (Refer to DIAGNOSTIC TROUBLE CODE CHART < CVT >, DIAGNOSTIC TROUBLE CODE CHART < A/T >). Then go to  Step 9.
    2. NO:  Go to Step 4.
  4. STEP 4. Read the diagnostic trouble code. 
    1. Use the scan tool (M.U.T.-III), erase the diagnostic trouble code of the cruise control system.
