One is this Battery Saver Mode that turns the A/C off. What is this thing and what's it's purpose? Number two is I can't get my scanner to link up to the car to pull any trouble codes. I'm assuming my scanner is in working order. I've never had a problem with it before. Anyone else having trouble getting a scanner to link up? BTW the car is a 2006 GXP.

A communication error that prevents the scanner from linking to the can system is either a bad connection at a computer or module, or a bad ECU.

This car is an OBD 2 isn't it?

Yes, any thing after 1996 on a GM car is OBD2.

Check the connector to make sure it has ground and power





Green is ground , Red is voltage....<br/>

Also, with your KEY ON , ENGINE OFF, see if the check engine light is on. If it is NOT on the car is not communicating with the computer. But if the car is starting n such , then its some weird issue with wiring or some data lines. If the car starts and runs fine , its unlikely something wrong with the ECU, but you never know these days.

and 1 more though, if your getting a message saying battery saver, it is likely the starting voltage of your car was in the 10 ,11's aka bad battery or depleted battery

Yeh battery voltage and load testing is usually the first place to start, I always assume people know to do this. lol
