You need to pull codes.

A majority of "SYS", are battery relatedI would check the battery for full charge & dirty connections, etc.

Hope it's that simple.

[sm=exactly.gif] Most often this is related to low voltage, for whatever reason.

If you have a interior bulb missing it will flash sys on the dash.

Paul, if you pulled the bulb while working on the lights-staying-on problem in your thread, you might be onto the problem there. That is, IF 'sys' can mean things other than low system voltage.

Betcha!?

I had the original stereo replaced with a Alpine stereo and my "sys" light has been on every since

RE: sys on dash
 

Thats because you or the installer didn't add a resistor in the wiring that eliminates that. If you want the instructions I can send them too you. There was a TSB that came out on it a few years ago. I have an Alpine also.

Please post or send directions. I've had the SYS error since I installed an aftermarket stereo! It's not hurting anything it's just annoying.
