Hey all I am working on a 2015 Infiniti q40
i had this car come in with u1001 code in the engine and u1000 can comm circuit in the abs module it also had the abs light flashing and the brake light on
i found the power on the battery was loose so i tightened it up and the abs and brake went away but now I am stuck with the two u codes and the vdc light on
i usually send stuff like this out but the guy I send it to had an accident is out for a few weeks so I’m stuck with it
I went through the grounds on the car and cleaned them up the car also had a sunroof leak and water seemed to have got by the bcm I cleaned the terminal up and plugged back in still same code
i puother bcm in with sam numbers and got same code immedietly
I also took a shot and changed the abs module still same thing
any ideas on where to start to diagnose this thing
thanks in advance
