Good evening
Today I did a gobble test with Diagbox on my Peug 407 HDi and found fault code for the gearbox.It was
"U2000 fault in synchronization of the main controlled reawakening request received by the CAN(BSI ECU) and the controlled reawakening control by wire"

Please help to understand what does this mean and what should do

U codes are network codes usually to do with communication between different parts of car and on its own means nothing as it may have been due to low voltage a temporary glitch or something you done.

As for what to do i would say do nothing unless there is an issue with the car you have not mentioned.

Yes, there is no issue so far. I cleared the code and hope to check again in few days.
