1990 FX3 suspension Codes
Pulled my 1990 FX3 suspension codes today. Everyone of them showed up on the dash. Where do I start checking? The suspension has always worked well.

I had the same experience on my 89. I've been told the memory on the FX3 computer is not large so the thing can get overloaded easily. I bought a brand new set of shocks, replaced the obvious leaking/bad one and all the codes cleared on just that one change. Perhaps you have the same situation or one or more actuators that have failed.
You can check the actuators by removing them one at a time, looking inside at the gear, and have someone turn on the ignition. The gear should spin one way and then the other in a self-check. If it doesn't do this, then the actuator is likely bad.

Has the Service ride control light been on long? Try resetting the codes and see what comes back.

FX3 codes
Well I pulled all acuaters today and they all work. Checked all shocks and no broken gears and all turn 3/4 of a turn freely. Again tried to clear codes and re-run diagnostics. Every FX3 code came up again. Starting to lose patients.

Clearing the codes can be a pain in the butt. If the timing sequence is off, it will fail. Best way is with a tech 1. The last option is that your ride control module has failed.

Won't discounted the battery clear the codes?

Yes, it is in the bin with the ABS. Not sure if it resets after being unplugged. As it does a self check each time the key is cycled to run.
