U2105

U2105 CAN Bus Error ECM (GM specific code) This GM specific code points to a problem in the high speed data line called the CAN bus. This data line carries digital information between modules. The problem can be a break in the line or a short in one of the modules that injects voltage onto the data line. A voltage on the line interrupts the flow of data. © 2012 Rick Muscoplat
