Diagnosis tool codes

These are some of the errors my buddy picked up with his scan tool about a year ago. Some of them are because of LED lighting.

My concerns are with the SAM. I haven't ran into any problems as of yet, again these pictures were taken a year ago.

Is there anything I can do to prevent a SAM going dead?

I was going to take a look but when I tilted my head, all the blood ran to the side and I got dizzy.

😂 Sorry Eric. I tried everything in my power to rotate those photos so no one would get a headache.

Anyway, you really ought to learn to interpret the error codes. It's not that hard; you don't even need a scan tool. Just get an OBD code reader. Then look up the code meanings. Group them as you already mentally did; some are lighting and unimportant. Others are significant, like SAM errors. Study them online and try to figure out if there is a pattern or a common cause.

If you get a MB-specific scan tool, there is a deeper level of information. But this is 10x the cost of a basic OBD tool. For another 10x, you can get a Star system. Most don't recommend that as a first or even a second step.

When you figure out something specific you're concerned about, post back. There aren't many that have knowledge to help with true computer issues, but most will try. That's where the fun begins.

Thanks for the response Eric. I am going to search the SAM codes as I feel that would my biggest concern. I'll post results here.
