Final DTC Checking

Information 

After repairing the problem using the DTC guide, it is essential to verify if all faults have been corrected.

In this case, check if the fault code is cleared by exchanging it with a normal sensor.

1. Clear the stored fault code by using the diagnostic equipment.
2. After starting the engine, search the fault code again.
3. Check if the fault code reoccurred in the diagnostic equipment.

   No fault code / OK 

   System is now working properly.

   Release the vehicle.

   Fault Code Regeneration / NG 

   Case1) some of the procedures are missing on the flow chart,

   → Go on to the missing procedure.

   Case2) If the same DTC returns, even though mechanic has completed the whole procedure in the flow chart,

   → It is possible to suspect a failure of the controller unit. Go to next procedure to proceed with the controller pass/fail decision.

Controller Quality Judgement Procedure

1. Replace with a normal BDC by referring to the appropriate service information.
2. If the DTC is cleared after replacing with a normal BDC: It is controller error so replace the normal BDC and release the vehicle.
3. If the DTC is still not cleared after a normal BDC is installed: It is impossible to determine the controller as the cause of the fault.

   In this case, place the existing BDC again, and check for the whole inspection flow again.
