Hello everyone, I just joined and very excited to say that I have an 85 Cadillac Seville Elegante I've had for 3 years. Now I'm starting to restore it part by part. I started out trying to sell this car for my friend and ended up with it for this length of time. I really enjoy the car and I hoping to get it restored within the next year. I have two mechanics for it that have the OBD1 scanner. One mechanic knows a lot and the other doesn't. The rear shocks were air suspension shocks and because they were old and cracking they are changed to standard KYB shocks. I unplugged the pump  but The dash light for the pump keeps blinking blue constantly. Neither mechanic really gives me a answer why it's blinking. Are there sensors for the suspension that I could pull a fuse on or disconnect somehow?? Thanks for your help, appreciate it.

Explain what you mean by standard KYB shocks, are they air shocks?

These cars are level balanced with the air shock, it is a necessary part of the suspension.  I do not know who would replace an air shock with a 'standard shock'.  If you ever put 4 adults in the car you will be on the ground, and if you hit a pot hole or dip in the road good luck.  The car is designed to be at a  specific 'ride height'.  The air leveling component is necessary.

Did one of these mechanics suggest this?  And why KYB?

Please provide more details.

If my memory still serves me You can not UNPLUG anything to make it go away. Need a resistor to match the sensor that send the correct value to computer.

No, I dont know the value...

This is true with the electronic struts.

Were these electronic struts in 85?  He might be getting a ALC message related to the air leveling suspension.  

He can pull codes, but pulling the codes for the suspension was a little involved on the 85, and might involve interpreting flashes once in suspension diagnostic mode. 

My oldest manual is 88.
