Hello, I have an 07 LS 460l with around 80k miles. Just recently I got a message on the dash saying "check power control system" and reccomends I go to dealer. I can't find any info about this message or problem. I found one post when I search about it but no answers. There is a fuse in the passenger fuse box #2 for a power control system. I am going to check the fuse, but I am still curious what this message is even referring to.

 

Check the error codes before "fixing" anything.

 

There is no CEL lit. It is just a message that cycles in the area where the odometer is. I have a generic scan tool so I can only really check codes when there is a check engine light.
edit: do you have any idea what the power control system is referring to? Also TY for your reply.

 

I suspect, it complains about the steering. You probably will need Techstream to read the code.

 

I just read up about what techstream is, I think I will give that a try. Thanks

 

I got a copy of Techstream and found the codes to be B22A1 and B22A8. I ended up cleaning my battery management sensor - "box connected to negative battery cable" contacts and connector and cleared the codes and it hasn't come back yet. I think it will need a new one soon. The car ran fine and never had any battery problems or weak starts while i had the problem. There were some pretty good troubleshooting guides online for the error codes. Just Google B22A1/B22A8. I will update if it comes back and if a new battery sensor fixes it for good.
