Question about 2008 Chevrolet Tahoe LTZ
I took it to work shop still nothing
So what is your Question ? Most of the time these U codes happen because of a bad connection . The first thing to do is check power and grounds for said module . Is this vehicle able to start an run ?
Modules connected to the serial data circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. The modules have prerecorded information about what messages are needed to be exchanged on the serial data circuits, for each virtual network. The messages are supervised and also, some periodic messages are used by the receiver module as an availability indication of the transmitter module. Each message contains the identification number of the transmitter module.
The body control module (BCM) and the serial data gateway module (SDGM) activate various modules by applying voltage to communication enable and wake up circuits when the ignition key is in ACC, ON or START. Refer to the schematics to determine which modules are activated by each wake up or enable circuit.
