Hello everyone, my in law's asked to connect the scanner to their CRV after he replaced an oil pressure switch due to a P2647, it’s good now. However, apparently a couple of years ago, it had some brake issues and he took it to a shop where they changed pads and possibly an ABS pump but not sure. He says the tech had large scanner and the tech told him he messed up something with the computer and couldn’t fix it, that he needed to take it to the Honda dealer. He didn’t charge him a dime for the work or equipment.
The car really doesn’t have any issues at this time other than the air conditioning that blows warm air sometimes.
All the codes seem to be communication related. It’s a CRV 2010. Any experience with this? I tried resetting the codes and it said abnormal communication.
thank you.

 

The are some checks that can be done on those F CAN lines, like a resistance check, and then a scope is required to see if something is corrupting the signal. Then figuring out what module is causing that issue.
It could be caused by a corroded connector or even a module that has a bad ground.

You may end up at the dealer to try to have a diagnostic done.
