Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
The only way to acquire repair information at this point, is to scan the complete computer system and sub systems with a scan tool and also see if any codes or pending codes are stored as well.
That would only point to a defective computer then if you can access the nodes but they don't give bad data or codes when a light is illuminated.
Thanks again, and please don't forget to rate me and keep this link in case you need me again later on.
Ahh, I see. So we're back to square one again. I thought you were getting data. We need the tool that can get what we're after. I can access this information with Autoengunuity if you have access to that.
Ok, you're onto or now. Check the wiring power and ground circuits.
Thanks, ***** ***** don't forget to rate me and keep this link for future reference and if you need more help.
