If the transmission upshift indication request message is missing for 1 second or longer, the BCM (Body Control Module) and IPC (Instrument Panel Cluster) set DTC (Diagnostic Trouble Code) U0100:00. If the transmission upshift indication request message is missing, the IPC (Instrument Panel Cluster) defaults the upshift message center indicator off.
