If you use an OBDII scan tool to delete Diagnostic Trouble Code(s), then how do you get the car I/M ready?


Asked by Aug 28, 2014 at 06:29 PM about the 2000 Mazda Protege ES

Question type: General

When you plug in an OBDII scan tool it should say: DTC 0 and IM Ready Yes
But after you get the check engin light and use the scanner to delete it it says: DTC 0
and IM Ready No.

How can you get it to say yes again because you need to be able to pass the
emissions test.

It has to set itself,drive car,and it will reset.


Thank you, but i just tried to use the RioRand RS300 CAN OBD 2 scanner today on my 2000 Mazda Protege and it gave me a link error. So i will now have to take it to a mechanic.
