Took it to a mechanic, they said suspension compressor and suspension relay don't work. They also said it could be something else, since computer scan doesn't let them go past that point.
Should I change the relay first? Could it be something else?
Where are the suspension compressor and relay located on the car?
What do you advise I do first?

I tried 2 new batteries and no power to car at all.

It takes a few attempts to start on occasion. The battery and alternator are good. Most times it starts and runs fine. Also, the car once died while waiting for a stop light. Then it started fine right after that. Could it be the grounding cable or some other connection? Suggestions on potential problems. Thanks.

The manual indicates to remove the screw securing the battery and remove the battery support and bracket. Where are these two items located as there is no apparent screw / bracket on the top side of the battery. However, the battery cannot be moved and is obviously locked in place. There is also no obvious screw or bracket looking from underneath the car as well.

the car won't start some times, the code showed bad CPS
