My 2002 eldorado collector series keeps showing code RSS c0577 and RSS c0579......what option in the IP override will allow the computer to stop looking at these values and stop setting these codes....the suspension has been changed over to a passive system.... I also have owned 4 cadillac allantes that I change to a passive systemI changed the input and never set those codes again....
Country: CanadaMake: CadillacModel: Eldorado ETC #558Year: 2002
Passive struts installed
Hello and thank you for trusting me with your question. My name is XXXXX XXXXX X will do my best to help you with your Cadillac problem.The C0577 and C0579 codes are for a short/open in the left front strut circuit. Changing this suspension over to a passive system means you need to install a resistor at each strut connector. Make sure the resistor is connected well and has a value between 9.5-15.5 ohms. This should take care of the problem and keep the message from coming up. If you would like any additional information or have more questions please don’t hesitate to ask!

I am a retired GM mechanic myself....retired in 1986..what I want to do is to stop the computer from looking at this input (RSS system) I should be able to select ( ignore) by entering the diagnostic system and changing the value like I have done to the Allantes......just don't know how to do it on the eldorado,,,cant find the info I need......there are 5 options in the IPS override A,B,C,D,E,,,,one of these must be for the struts.....I belong to alldata.com and cant find any info there......
This system does not have an override to disable the inputs to the driver information center (DIC). All of the modules in the vehicle are tied together through the serial data line. When there is a problem, this is communicated through to the DIC and shows up on the display. The only way not to get the message to show is to fix the original problem. Even disabling the suspension module (CVRSS module) will cause codes to set in another module and turn on more warning lights. See in the diagram below how the module is tied in directly to the ABS module and also has other serial data signal wires going off to the other vehicle modules.

Ok....so what do the 5 options represent ?
The override options are typically lighting system ouputs. Warnings cannot be overridden in this system. There is a problem in the left front strut. You can either replace the strut or bypass the struts internal solenoid with a resistor to get rid of the fault and prevent the warnings from appearing. This is the only way.
Well.....I don't think this info helps me a lot,I already knew what the codes represent,but I am looking for a disable feature,which I am sure exists,are you aware of how it is done on an Allante ? You tried ,,,,,,so I will close out this request and give you a favorable positive feedback,,,,,I will let you know when I get the result I am looking for......
The Allante system is completely different than the newer cars. I too am familiar with the Allante, having worked for GM from the early 90s up through 2009. Thank you for the positive feedback. If I come up with another solution to this I will reply back and let you know.
Thanks for your efforts Dave......you gave it a good try......I will try to save all your info.....Ray
You are welcome.
Well its Monday and I went back to the car and removed the actuator (coil) from the left front wheel,,,,,,,,,,,,,,,and sure enough the coil is open,,,,,so for now,,if I can find a resister of the proper value,I will put it in.....so I would say you are right on with your diagnosis....I have tried to pay you but can't click on your happy face....will it come in time ??? Thanks again RAY
Not sure about the system here. It seems we are having some problems with it. I can have the site administrators handle the payment on this end. thank you for the positive feedback.
NP....... A 15.14 ohm resister seems to have cured the problem.....Ray
Glad that I was able to help you with this problem.
