Hi I am Daniel
Your probable cause is a bad electronic brake control module. But Connections and wires need to always be checked.
I can supply testing and diagram if this would help if you are doing your own work.
Would the pump/pressure switch also need replacement
No not if those are your only codes.
I thought that might be the case. I was told that the pump might also be defective which would in turn take out the replaced control module which they referred to as a relay of sorts.
yes the relay is intregrated into ecbm and is not servicable
If youhave any questions or requests please let me know.
I believe there was a issue in chat so I switched us to Q and A. Let me knoiw if you have any other questions at all even after accept. Dont forget the green accept button.
he should be able to a fuctions test on the switch and prove it is bad. yes usually if there is not a error code there isnt nothing wrong with it. But. I have seen sensors that were bad that have not thrown error but I tgested them with a scanner and did a funtions test and compared it to a know good running pattern in my scanner. My program as his should have a complete program. Thanks for letting me clear that up for you.
