Instrument Panel Cluster (IPC) contains a momentary switch that controls trip odometer reset and trip season display options. IPC monitors circuit voltage levels and detects when trip odometer reset switch has been depressed. DTC B2823 is set when IPC detects that trip reset switch input is low (grounded) for more than 60 seconds.
When DTC B2823 is set, IPC will disable (ignore) trip reset switch. DTC B2823 will clear and become a history DTC when IPC no longer detects a failure. History DTC B2823 will clear after 100 fault free ignition cycles. DTC B2823 will also clear when IPC receives a clear code command from scan tool.
