Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello and thank you for your question. My name is ***** ***** I will help you with this concern.In most cases providing the scan tool your using is not defective the fact that the scanner will not communicate usually means you have a problem with the PCM (computer) and if in fact that is the case this is going to need to be addressed by your dealer. Have you tried connecting a factory scan tool?
Is the check engine light flashing?
Okay you should be okay if its only every now and then but if the light start flashing on a regular basis then you do NOT want to drive it because it can cause damage to the Catalytic converter.
