I was just wondering if any one else on this site has had the same problen that I am currently experiencing. Recently the check engine light has been flashing on and off occasionally so I tried to hook up my snap on modis scanner to get the codes but it keeps saying there is no communication. If I try to get codes from the tcu it works fine, it just don't work for the ecu. This is really baffleing because the car runs fine otherwise. Any help that anyone can offer would be greatly appreciated and thank you in advance.
