2005 Pontiac G6 V6 3.6 liters.
Warning lights: check engine light.
Computer codes = Don't know yet.
Question = I have a 2005 Pontiac G6 with a check engine light on. I got a OBD 2 scanner to scan the codes. So i connected is to the DLC port under the dash to see what codes would come up to see why the light is on. When I ran the scanner to link up, it didn't get any codes it just said error.
I had the key on to on position, but was not started. I thought maybe my batteries in my scanner was weak, so I put new batteries in it and ran the scanner again, and I got the same reading, 'error.' I decided to see if maybe my scanner wasn't working correctly, so I unplugged my Mass Air Sensor on my 2003 Chevy Silverado and started it up until the Check Engine light to come on and run my scanner to see if it was working properly, and it was, it gave me a code and it looked it up in its manual and it told that it was the mass air sensor. So after giving you all this information to get to real question, is there maybe something wrong with my DIC to where my OBD 2 scanner won't connect to the car's computer, or is there another way to get the code(s) from the car?
Answer: A regular OBD2 scanner will not work on your vehicle. It has newer serial data architecture. The system is a LAN- Local area Network, similar to an office or home network and requires the use of what is called a CANdi module. This separate module makes the communication possible to retrieve diagnostic trouble codes from the computers and modules on the car. Your Silverado has the older serial data architecture, and that's why you were able to pull the code from it. You'll probably have to take it to a dealership where they have the proper tools to diagnose the problem.
Sunfire Starts And Dies
I have a 07 g6 sunfire it starts and runs for awhile then dies and and the set air bag starts flashing an it wont start again until u jump it off.
Answer: If it dies out and you have to jump start it it get it going again, then you have a bad battery or an alternator that is not charging. With low system voltage in your Pontiac, the computer dont like that. It seems that the first computer to act up is the Airbag module since that warning light comes on just befor5e the car dies out. Have the charging system and battery tested.
