Customer Question

I have a 1994 Cadillac concours 4.6 liter northstar engine. The service ride control light will not turn off. My mechanic thinks it's a bad module box in the trunk. Delco chassis part #22154810.
What do you think?
The car is in beautiful shape, and this warning light drives me crazy!!!
Thank you.

This is the part.
Customer: replied 1 month ago.
I can get you the code numbers from my mechanic in the morning. Will that help?
Expert:  Dan replied 1 month ago.

You can check them yourself too, here are instructions. I need RSS codes. Let me know, thanks.


Customer: replied 1 month ago.
I hope you're still out there...The codes are: SO55 and SO73. Any help will be appreciated?
Expert:  Dan replied 1 month ago.

S055 points toward a failed RSS module and S073 could mean module or accelerometer so I agree replaceing the RSS (Rear suspension Module) is best place to start. You can get a used one from salvage yard or if they do not have one locally. Let me know if you have questions, thanks.
