Check whether the MFI system-related DTC is stored.
Is the DTC stored?
Diagnose MFI system (Refer to GROUP 13A - Troubleshooting ). After diagnosing the MFI system, go to Step 6.
Go to Step 3.
 
STEP 3. Using scan tool (M.U.T.-III), check data list.
Check the vehicle speed signal data list of MFI system.
Item No.4: Vehicle speed signal (Refer to GROUP 13A - Data list reference table ).
Is the check result normal?
Go to Step 4.
Diagnose MFI system (Refer to GROUP 13A - Troubleshooting ). After diagnosing the MFI system.
