Hello, I have a dic error code C0594, which is the RR Solenoid circuit open. Where should I start with this error code on the car?

Thanks

Ok here we go...

I assume you have a 2003-2004? Equipped with F55 suspension. (The switch on the console that says Tour/Sport)

This code may be the beginning of the end for your suspension, or a simple fix. Best case the connector came off the top of the shock for some unknown reason. Worst case the shock or controller has failed and require replacement. Have a look at the connector and harness and report back.

You do not state if the code is current or historical.

Pulled the connections off the shock and cleaned. Was not dirty.

Now I have a new error code, 10-PCM PP1280 HC.

Any ideas what to check futher?

All checked out and looked good, cleaned and re-connected back.
A new code has now appeared, 10-PCM P1280 HC,
Where do you think I should check now?
