Anyone here being able to help me with a small problem concerning my 94 eldorado 4,6 l northstar? I´m living in Germany and the number of Cadillac specialists is very limited here and I do not have access to a proper manual to deal with this failure.
Following is shown on the display after engine start:"service ride control".
After checking out the bite module, the following failure messages are displayed: "S023 history, S060 history and S030 current".
So I have the following question: where are the applicable sensors installed?, how can I solve the problem and how can I probably change the devices? Up to now, I have no problems during operation of the vehicle, the suspension and steering systems seem to operate normaly.
Beside of these fault indications, I can say that I`m absolute satisfied with this car and its fine engine. Hope somebody can help me.

Thank You very much in advance
Ralf

 

check the sensor on the front wheels
and rear suspension

 

Thank you very much, will try this. One more question: where precisely are these sensors installed and how can I check them?

Thanks again
Ralf

 

if u look at the front lower control arm u will see a rod connecting to arm and little box
those links usually separate

 

Thanks a lot, will try this over the weekend. Give You reply then.
Once again Thank You very much
Ralf

 

Hello gmtechs, tried your advice. Could find no abnormalities, the problem still exists. Both heigh sensors front and the two lower shock strut sensors where in place. All plugs connected. Do You have an idea where can I find a list of all sensors with their respective identification/number(..S023 for example) and their installation position? Do You know, how I can possibly test the respective sensor? Any other Idea to solve the problem? Yours Ralf

 

here is a place for dtc http://myweb.accessus.net/~090/dtcobd1.html#cus

u need to take each plug out and measure the resistance in the sensor to see if it changes
u also need to check the other end power and ground

 

checked the diagnostic trouble codes on this website but found no S023. Any idea??
Greetings Ralf
