DTC U2300:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC U2300:00	Global central configuration error
DETECTION CONDITION	Any of following conditions occurs: No configuration of the instrument cluster. The configuration signal with the estimated CAN ID is not sent from the instrument cluster. The configuration signal value sent via CAN from the instrument cluster is unknown or invalid. The configuration signal value sent via CAN from the instrument cluster is a value other than the estimated value. The configuration signal value sent via CAN from the instrument cluster does not match the PCM value. Diagnostic support note This is a continuous monitor (other). The check engine light does not illuminate. FREEZE FRAME DATA is not available. Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Operates by the previously learned configuration value.
POSSIBLE CAUSE	CAN drive error (instrument cluster or PCM) Configuration data for the instrument cluster is incorrectly set CAN communication line malfunction between instrument cluster and PCM Instrument cluster terminal 1B-Body control module (BCM) terminal 2D Instrument cluster terminal 1D-Body control module (BCM) terminal 2C Body control module (BCM) terminal 3C-PCM terminal 2S Body control module (BCM) terminal 3D-PCM terminal 2T PCM connector or terminals malfunction Instrument cluster connector or terminals malfunction Instrument cluster loose Instrument cluster malfunction Error in non-volatile memory in PCM PCM malfunction
