The OBDII connector is on the same circuit as the cigarette lighter. A lot of times a cell phone charger or other device will blow the fuse and cause the scanner not to power on or communicate. I would just double check the cigarette lighter fuse. Also, maybe try a different place. Pep Boys isn't exactly known for hiring the most qualified technicians.
As or the remote start. It isn't working because of the check engine light. For some reason on late model GM vehicles, having the check engine light on disables the remote start system. Once the problem is repaired and the codes cleared the remote start will work again.

Your vehicle does two types of evaporative leak detections by the on board diagnostics. Depending on the test your a getting a gross leak detection fault this is usually caused by a faulty fuel cap that is not holding the vapor in the tank. The tests have to be done under set conditions so the problem will only occur when the test is commanded and the test fails. You will get the fuel cap then the check engine light.

Yellow warning light that says check is on What does it want? In manual it says take to dealer


Take it to a Pep boys if you don"t have a code reader.
They will check out the computer code warning you are getting right noe.
The cost will be about $40 or 50 bucks.
The dealer will charge you three times that much,plus Pep boys will give you a up front free estimate if you need any repairs.
Bet it's the gas cap though.
Try tightening your gas cap and driving the car around far a hundred miles or so.
remember never put gas or loosen the gas cap when the engine is on.
The computer will pick up the venting like it would a leak,thus sending a warning code to the computer.

My engine light is on in my 2007 Chevy Suburban LT. I changed the fuel cap, but the light remains on. Is there a reset mode for this problem, or do I need to put my truck in a repair shop.


If you had the check engine light checked by computer and it came back as a loose fuel cap, it could also be the egr valve or a small vacuum leak. I would first go to autozone where they can check it for free and most of the time reset the light for you at no charge. They will also explain how important the code is and you can purchase the replacement part right there. Sometimes they can show you where the part is that needs replaces. I hope this helps.

Check engine light stays on


You need to have your engine fault codes read to know what to look for. That is why it is on. Go to almost any auto parts store like Schuck's/Kragan/Chief's Pep Boys/Auto Parts Plus/Auto Zone. They have a tool you can use or they will do it for you, FOR FREE.

This will let you know why you have the check engine light on.
