Code U0029 2016 Chevrolet Silverado Description

The Media Oriented Systems Transport (MOST) bus consists of a physical ring in which multimedia devices share audio, video and infotainment system control data. Each device on the MOST bus transmits and receives data via the MOST Bus Serial Data (+/- transmit/receive) circuits. The MOST bus diagnostic master is the Radio. The MOST control circuit is connected to each device on the MOST bus. Each device provides a 12 V signal on the MOST control circuit. The Radio initiates communication on the MOST bus at Ignition ON by toggling the MOST control circuit low for 100 ms. Once each device recognizes the wakeup signal from the Radio on the MOST control circuit, they will respond to the Radio on the MOST bus to indicate no faults are present and normal communications will commence. The MOST bus master device shall set DTC U0029 when the MOST bus interruptions last long enough to interrupt MOST communication and functions, but not long enough to break the MOST bus ring. A current Diagnostic Trouble Code (DTC) sets when MOST bus communication has been interrupted more than 10 times during the monitoring cycle period.
