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?
