Default what does sys mean

In the center of the dash in the information area it keeps flashing sys every so often I'm guessing the fuel econ unit is going bad. anybody else run into this?

I think it generally means a communications problem between the ECM and CCM, but I'm sure someone will jump in if I'm wrong.

Yes, but you'll need to pull codes to narrow down what's going on with your car.

It could mean a number of things... do you have an aftermarket stereo? How old is the battery?

Check this out... C4 Guru - Reading CCM Codes 1992/1993

This is focused on the 92/93 years, but others are close.

Default Sys display

Mine has done it on ocassion. But it does it right after start up, flashes three times and goes to its regular function. Nothing seems to be affected, all instruments seem fine.

Generally it means electrical system problems. This could be battery problems, alternator problems, or that an aftermarket stereo has been put in and is not returning the right resistance value.

I had the same problem last week. It turned out to be a blown fuse that feeds the interior door lights. However, as the others say, it can be a lot of things. Good luck.

It means the CCM has a code stored. Normally this is an electrical problem, and in most cases something minor. Check the codes in your CCM and it'll tell you what's wrong.

It's a good chance it's just the battery.

Great PDF file, but where is the connection located where you read the codes? Under hood, dash? Thanks.

I have recently been having the same problems, I saw the SYS light up while driving down the road, and the interior lights will not go off, I checked the fuses to find the fuse for the doors and under the dash was blown, I pulled another 5 amp fuse from another slot and plugged it in and all of the interior lights were on and would not turn off. I read that there are CCM codes to read, do you have to have a special electronic device to display these codes? What should I do....? for now I am pulling the fuses for the interior lights until I can fix it. One other note...two weeks ago I left the key in the ignition turned on while waxing....to say the least the battery was dead three hours later, I hooked up a trickle charger and left it on for one day and have had no problems with battery since, but the problems started after that, exactly when I can't say.
