Code U2098 2016 Chevrolet Silverado Description

When the ignition is ON, the Radio initializes the Media Oriented Systems Transport (MOST) bus by sending a short 100 ms low voltage pulse on the electronic control line (or MOST control line) connected to all devices contained on the MOST ring. When MOST receive, transmit or control line faults are detected, transmit/receive messages will not receive as expected from the wakeup request. The Radio and the Human Machine Interface Control Module will then perform diagnostics to isolate these MOST faults. If the MOST control line is shorted low to 0 V for an excess amount of time, the Radio and the Audio Amplifier, if equipped, will set a U2098 Diagnostic Trouble Code (DTC), and Human Machine Interface Control Module, if equipped, will set a U0029 02 DTC. At this point, the MOST bus will be unable to communicate until the shorted MOST control line is repaired. The DTC will be set when the Radio senses a short to ground on the MOST control circuit.
