DTC code 2019 honda civic EX U0100 Lost Communication With ECM/PCM A was created by assem.nagi
Hello friends I tried reading the codes for my 2019 honda civic EX and got two new codes.
U0100 Lost Communication With ECM/PCM A.
U0038 Vehicle Communication Bus B Performance.
The vehicle is a push to start and wont start at all the engine is a L15BA and the intake are not attached to the engine yet if that's a possible cause.
Any info on how I might be able to fix this issue like where to start and so on is greatly appreciated.
Thx again.
