Default Common failure FX3

Hi, this is my first post. I have problem with the FX3, it will not work when I put it in the three different setups. I have checked the coilnut under acctuator and it was brooken, but the acctuator does not turn either. What is the next thing to check?

Best regards from Sweden

You didn't mention year and there are subtle differences in the parts and the actual operation. Do you have a FSM? You'll need to actually use the diagnostic trees in the FSM and do your own diagnostics. Have you checked all of the positions? Have you checked for failure codes of system?

It's helpful if you include the year of the car. As WVZR-1 mentioned, there are variances in the Selective Ride Control systems.

The link is a good one an you should read the "Diagnosis" page.

I assume that the "Service SRC" light is on in the DIC? You should pull the codes to see if that one actuator is the only problem. Post the codes here. Note that there are individual numeric trouble code for each of the 4 actuators.

Welcome to the C4 Forum. I have found a lot of good info on here. Did your system ever work? For me and my 1991 someone had de-commissioned the system before I ever owned it. I restored my FX3 system and did a 9 minute video on it. It is here on youtube:


Hope this helps.

Hi again, I forgot to introduce myself and my car. Magnus is my name and is from southern Sweden, winter is just out and has just taken up the Corvette. It's a -92 convertible bright aqua met with white interior.

The error codes I have checked and they show nothing wrong, I pulled out a list from the web.

Just as flyboyslc1 I had my wife to help when I checked actuators, a very good and informative movie, by the way thanks.

actuator does not move when I turn the key and I have checked that they are linked.

I will take it apart and look for some electric failure.

/Magnus

Your '87 does NOT have FX3, the option wasn't even available until '89.

Default To get ride control codes.

On my 1991, which may be the same as the 1992, to get the ride control codes I used the following procedure.
Ground pin C of the ALDL connector to pin A.
Turn the ignition to ON.
Read the codes.
Turn the ignition OFF.
Remove the jumper between pins A and C.
