Hey everybody. i have a 94 deville that recently had the service engine and ride control messages come on. All of the code readers that i see in stores say that they are for cars 96' or later. I just want to know what to expect before i put in the shop. any help is greatly appreciated.

 

Car has on board diagnostics, you dont need scanner. Press off and red warmer buttons at the same time for 5 sec. codes will come up.

 

good look thnx
