DTC Check / Clear [03/2023 - ]

for Mexico Models 

HINT: 

• DTCs which are stored in the ECM can be displayed on the GTS. The GTS can display the confirmed, pending and permanent DTCs.
• If a malfunction is detected during the current driving cycle, confirmed and permanent DTCs are stored.
• Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
• confirmed and pending DTCs can be cleared by using the GTS or by disconnecting the cable from the negative (-) battery terminal. However, permanent DTCs cannot be cleared using either of these two methods.
• After clearing current DTCs using the GTS (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

  To clear permanent DTCs, all of the following conditions must be are met:

  • There is a history that universal trip driving was performed.
  • The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)
  • No malfunctions are detected.

HINT: 

• Obtaining a normal judgment and performing a universal trip driving pattern can be done in the same driving cycle or in different driving cycles.
• It is unnecessary to obtain a normal judgment if the output DTCs are misfire or fuel system DTCs.

1. CLEAR PERMANENT DTC 

   OUTLINE 

   1. After clearing current DTCs using the GTS (or by disconnecting the cable from the negative (-) battery terminal), permanent DTCs can be cleared when the universal trip is performed and then the system is determined to be normal for the relevant DTCs. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.
   2. To clear permanent DTCs, all of the following conditions must be are met:
      • There is a history that universal trip driving was performed.
      • The vehicle has been judged as normal for 2 trips. (Normal judgment does not have to be performed in 2 consecutive trip, but normal judgment should occur in the latest trip.) (not for misfire and fuel system DTCs)
      • No malfunctions are detected.
   1. Connect the GTS to the DLC3.
   2. Turn the ignition switch to ON.
   3. Turn the GTS on.
   4. Enter the following menus: Powertrain / Engine / Trouble Codes.

      Powertrain > Engine > Trouble Codes 

      HINT: 

      If "PERMANENT" in the top right of the screen displays "YES", permanent DTCs are stored.

   5. Select the "Generic" tab.
   6. Check if permanent DTCs are stored.

      HINT: 

      If permanent DTCs are not output, it is not necessary to continue this procedure.

   7. Clear the DTCs.

      Powertrain > Engine > Clear DTCs 

      NOTE:

      Do not clear the DTCs or disconnect the cable from the battery terminal after performing this step.

   8. Perform the universal trip.

      HINT: 

      The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle.

      1. Start the engine and wait for 30 seconds or more.
      2. Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more.
         WARNING:

         When performing a driving pattern, obey all speed limits and traffic laws.

         HINT: 

         It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes.

      3. Allow 10 minutes or more to elapse from the time the engine started.
   9. Turn the ignition switch off and wait for 2 minutes or more.
   10. Turn the ignition switch to ON.
   11. Enter the following menus: Powertrain / Engine / Trouble Codes.

       Powertrain > Engine > Trouble Codes 

   12. Check that the permanent DTCs have been cleared.

       HINT: 

       If permanent DTCs are not output, it is not necessary to continue this procedure.

   13. Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.

       HINT: 

       • Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs.
       • Do not turn the ignition switch off by mistake during this step.
   14. Start the engine and wait for 5 seconds or more.
   15. Turn the ignition switch off and wait for 2 minutes or more.
   16. Turn the ignition switch to ON.
   17. Enter the following menus: Powertrain / Engine / Trouble Codes.

       Powertrain > Engine > Trouble Codes 

   18. Check that the permanent DTCs have been cleared.

       HINT: 

       If permanent DTCs are not output, it is not necessary to continue this procedure.

   19. Perform the normal judgment procedure in the respective confirmation driving pattern of each output DTC.

       HINT: 

       • Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs.
       • Do not turn the ignition switch off by mistake during this step.
   20. Start the engine and wait for 5 seconds or more.
   21. Turn the ignition switch off and wait for 2 minutes or more.
   22. Turn the ignition switch to ON.
   23. Enter the following menus: Powertrain / Engine / Trouble Codes.
