How do I get my remote start to work when the check engine light is on

You'll need to have the computer checked for trouble codes to proceed.

Need more information. Does the car start normally with a key? Is there a switch for a mechanic to disable the remote start while working on it (some units have a toggle switch)

Yup and it won't work till you get the check engine light fixed, what ever is causing that to come on.,it is a safety feature if there is a service vech. soon light on the remote start does not work !

You have a check light on

They have been on all vehicles for 32 years
Nothing new there

Check for Codes & Diagnose accordingly

By a cheap odb2 reader read code then delete codes,,with no check engine light on it will crank with remote start ,,a few times,,,,or til the light reappears ,,,you can also take the neg cable off the battery for 30 seconds to clear the codes,,, remote start should work after that if no engine light

a bad hood ajar switch would do it

The remote start on this vehicle will not work if the check engine light is on.You will have to have the codes checked and repaired in for the system to work.You should also check to see if you are still under the factory warranty.It is 3 years and 36k miles.If you are over this then you are not under warranty.Hope this helps.Good luck.

henryj153, no offence guy, but if you dont know something, dont try and give advice. Now for the guy with the problem mattpointer:
These cars come with remote start as an option, and it is problably your BCM (Body Control Module), which is a $380 part, and the dealer has to install it, because of the programing... Here is a free way of checking if that is it. This part ties in certain vehicle systems, and for some reason when the BCM goes bad, so does the GPS, that is tied in with OnStar Check to see if your onstar can recieve GPS... press the blue OnStar button and ask them to locate you. If you dont have the service, they may want to start the service, just humor them as if you were interested, and ask them to locate you first, because you want to make sure the equiptment works. If they cant locate you, but you are able to use OnStar to contact them, most likely The BCM is bad, and thats what it is. This car has some great technology, but the intergration of this tech is in the BCM, and it goes bad.... so its a trip to the dealer for you my friend.

It's a safety feature. For example, if there is no oil pressure when you start the engine, you could not see that unless you were in the car and could spin a bearing or seize the engine by starting it remotely and letting it run unattended. So when the check engine light is on, there is something not working properly with the engine/engine management system and it wants you in the car where you can see the guages and turn the engine off immediately if there's a serious problem.

Any time the Service Engine light comes on the remote start is disabled for the engines safety. As far as the SES light, your dealer should be able to help you with the diag.
