I have a customer vehicle and cannot find much about the troubles they’re having.
Having B1004 code with voltage retaining devices. Was thinking to replace this device I wonder if people have and good ideas how to test etc.
Had some trouble starting battery is fine. Have ran tests
It goes to crack about half a turn them stops then does the same.
I was originally called for DPF problem used a mityvac to test the DPF pressure sensor and was way out of tolerance change sensor and hadn’t changed I’m assuming this is down to electrical any help or suggestions are greatly appreciated.
