It shouldn't as ride control only effects the the comfort of the ride and not its safety... but believe me any warning light will trigger a possible failure. Most inspectors really only have rudimentary knowledge of how certain models work and will fail you upon inspection. Probably a bad shock...get it fixed

On my car, which is the same as yours, it is located on the manifold top back left. Pictures in the book just show it on top.

This is the part that you will need to take care of that anti theft issue.. Do It Yourself GM Security bypass

Yes. You're good

• The magnetic ride control system senses speed and oscillation of suspension and adjusts shock dampening for a comfortable ride. If a shock is bad or the suspension sensors are damaged in anyway the system deactivates and does to a default setting, and the warning comes on. Did you hit any real bad potholes? or probably just wear and tear.. You need to have your suspension system checked.. shocks, control arms, alignment, etc.

There is a fuse box under the hood, on the right side, clearly marked. There is a stabilization bar that runs right over it, which must be removed. The plastic cover that the already visible fuse panel is accessible through can now be lifted off, exposing the relays and larger fuses for additional electronic items, including the power door locks.

There is - fuse D5 (10A) in the engine compartment fuse block.

CHECK BATTERY FOR CRANK POWER.

Sounds like the door release actuator is sticking. Try lubricating the latch when the door is open. In addition to using the button on the dash, you should be able to open the door pulling the wire adjacent to the fuel door inside the trunk.

The actuator should be accessible from inside the trunk behind the trunk liner (just follow the wire). You should be able to remove the actuator and manually push the latch.

Give the dealer your vin and they will get you factory replacements

Lube the latch unit.

sounds like a security system issue.

Knock sensor is on the right (passenger) end of the engine, and will activate if at least one of the cylinders is misfiring. Your rough running engine can be caused by many many issues - I suggest you start with plugs and plug wires.

If you cut any wires you could be in for a lot of problems. I am not sure what year Cadillac made it so you could not put after market stuff in, but if you tried it would mess thing up and would have to take it to the dealer to fix it.

KEY ON ENGINE OFF 40 TO 50 PSI

Sounds like the module inside the distributor is starting to fail. If the engine turns over at normal speed but won't start then grab a spark checker and put it at the end of a spark plug wire and crank the engine. If if sparks then you have a fuel problem. If no spark then look to the distributor module or possibly the wiring harness inside the distributor. I have seen where the power wire, pink I believe, goes open at the black plastic box connector inside the distributor and can be tested with an ohmmeter. If that is the problem then replace the 2 wiring harnesses that make up the distributor wiring harness because the plastic connector will break apart when trying to remove the terminal and that makes it difficult to put back together. Hope that helps
