Hey guys!

I got a quick question regarding the inspection of the ECU pins. From what I've seen, the CANbus system uses 2 pins that connects in the same module. Is there a way I could test them with a multimeter? (Sorry if it's a dumb question )

I'll try to send a picture of the pins I'm trying to inspect so it's easier to understand.

Thanks1

Test them for what?

I've noticed that the modules connected with those pins give me codes telling me there's a communication error between them and the ECU. So, when it happens again, I wanna check if the ECU is fine

You can get a lot of U**** codes that are basically meaningless. They happen a lot with aftermarket scanners that the ECU doesn't like. If you are getting an actual error you will get a proper code for the module that you are looking for.


Most of the time you can completely ignore them
