Default HELP...SYS display while driving

What should I look for? I know that when the battery is low on voltage it will display this message but my batter is fine and the alternator is fine. Nothing seems to affect the driveability but the message blinks non stop.

Can anyone suggest anything?

Any mods done recently? Even one's that you would suspect could do it. On mine it was changing the radio, I had to run a dedicated constant 12 volts or about every 10 to 15 seconds that "sys" would flash.

It went away.

I didn't do anything at all!

Drove it all day today and it was fine.

I guess we'll have to wait and see if it comes back.

Thanks for all the suggestions.

I can't really remember but it you have an aftermarket radio and have the dimmer hooked up you'll get the sys light.

I do have an aftermarket stereo but it's been in there for a while and hasn't flashed before.

I just installed a new aux fan relay and an updated custom chip from Fastchip. Do you think the chip could be causing the issue?
