If the traction control indicator request message is invalid for less than 5 seconds or if the IPC (Instrument Panel Cluster) does not receive the stability-traction control message for less than 5 seconds, the IPC (Instrument Panel Cluster) defaults the stability-traction control indicator (sliding car icon) to the last indication mode (on/off) based upon the last known good message. If the traction control indicator request message is missing for 5 seconds or longer, the IPC (Instrument Panel Cluster) sets DTC (Diagnostic Trouble Code) U0121:00 in continuous memory and defaults the stability-traction control indicator (sliding car icon) on.
