My 95 also flashes the SYS light at me. I even put a new battery in it and
it still does it. The manual says that it is an electrical problem and to
see the GM Dealership. So I did. They said that it was a short to ground in
the instrument cluster. The only way to fix it is to replace the entire
cluster. But the good news is that it won`t effect anything else because
further diagnosis showed that it is my digital read out. It will dim and get
bright while normal driving. This is something that I have just learned to
live with. No big deal. The battery is not the problem. You can also use a
paperclip to run the troublecodes on your speedo readout. Hope this helps.

There are two main reasons that I have seen the SYS error:
1. The Battery is failing
2. An aftermarket Stereo was installed and the Resister modification was not
done at the time of the install. This needs to be done on late model C-4s.
I am sure there are other reasons but those are the two common ones I know
of.

________________________________________________
Sys indicates a problem detected by the CCM. The Sys light will flash 3
times every 15 seconds. To verify the problem, the CCM codes need to be
read. The service manual walks thru the steps to read and interperet the
codes using a jumper (Between A (ground) and G (Diagnostic Enable) on the
diagnostic connector. If you jumper the the two terminals and then turn the
ignition on (do not start the car), the CCM will go into auto mode and step
through all the modules. Module 1 is the CCM, module 4 is the ECM and
module 9 is the EBCM (ASR/ABS). The code is shown on the speedometer
readout with the module number shown below. The CCM will show C12 if all is
OK for the CCM. For the others, the display will be --- if no code is set.
All codes for the ECM and EBCM will be history codes ( H in front of the
code). Also CCM will be a History code if problem occured in the past and
is not present. After auto mode module 1.0 will be shown which is the CCM
waiting for further instructions. Turn the ignition off and pull the jumper
and you are back to normal CCM operations. If you feel uncomfortable about
playing with the diagnostic connector or can not tell which pins are which,
then have a technician read it for you.
For info, ECM will set a code for low voltage (DIC 53). The manual has
warnings about charging the battery in vehicle with electronics connected.
I am currently fighting an intermittent ASR/Sys/Security light indication.
I read the codes and the CCM and EBCM are telling me I have a serial comm
failure and this results in a FEDS failure. The problem is intermittent.
Anybody out here in cyberspace had this problem and fixed the problem? What
was the fix?
