SYS blinking on dash
I know the SYS means system error. I ran the car a week ago to keep the engine freed up and battery charged, michigan winter sux, anyways, all was fine.
I started it today, and where the gas mileage, gauge numbers go in the LCD, would blink SYS three times, then return to showing coolant temp, then about every 10-15 seconds, would blink SYS again.
I shut it off, and restarted it 5 min later, and it was fine. didnt blink SYS for the 20 min I had it running.
what would cause that? this stuff is all new to me.

my only rebuttle to that would be, why when I shut it down and restarted it, was it not flashing the SYS?
it did not start hard but it is 12 degrees here and has not been started in a week or so. it turned over but took an extra 2 cranks or so to fire.
I dont mind replacing a battery, I replace 2 things on every car I get it seems.
battery and tires
dont matter if I have them a week or 5 years. I always end up replacing them.
I just put a battery and tires on my truck. why not this also, I just put rear tires on it. why not a battery to compliment them?

Blinking Sys
Interesting responses to your SYS blinking. I JUST posted a similar thread today, as my '93 just started doing the same thing.
I will see if I get the same replies and let you know if I get anything different. Also in Michigan, maybe it is something in the air up here! Surely NOT spring in the air!

My '96 had the same blinking SYS light. Had the battery load tested and at least one cell was dead. Bought a new battery and never saw the SYS again.
Oh, also bought a battery tender. Great battery maintainer. Problem solved.

I just had this same problem today.... And this is the first year that i hadn't used any battery tender (idiot!).
What code would show if you simply have a weak battery?
Do you pull the codes the same way for "SYS" codes?

Replace the battery. The SYS will flash when only the CCM monitors an error. If a code is set, it would be in module 1 and you can get it by going into the diagnostic mode to retrieve the code. A lot of the time as many know a battery in poor condition will cause the SYS to flash. But there is no code for low voltage so you will not see a code that was set.
Codes will be cleared if 100 ignition cycles occur with no further problem, its cleared in module 1.7, or the battery is disconnected.
I think a new battery will fix you just fine.

I have the sys light flash on my 94 LT1 - then, I got "odo err" where the mileage is. It's currently in the shop getting new head gaskets. I got the vette at a pretty good price and the seller said that there might be a leak because it was throwing white smoke at start up (and was losing collant without leaking it!). Anyway, the seller put in a new battery, a Valuecraft which is the lowest model at Autozone. Do you think that this crappy battery may be the cause of my sys light and odo err? I bought a autoxray code puller off ebay, but the seller sent it FEDEX with sig required and anyone who buys off ebay knows what that means...if you're not home from 8-5, you don't get it. Any ideas?

kcrick- Does your car have an aftermarket radio/headunit? That can also cause the SYS light to flash.
There is some information in the Audio section regarding how to fix that.
