U0423 - Invalid Data Received From Instrument Panel Cluster Control Module...Possible causes; Invalid data network concerns, data is transferred within the normal inter-module message, but contains known invalid data. The transmitting module logs a DTC related to the invalid data concern. Missing message network concerns missing message concerns are logged by the module upon failure to receive a message from another module within a defined retry period...Check for other Powertrain Control Module (PCM) codes or PCM related symptoms. Diagnose all other PCM codes or PCM related symptoms first.

Basically what the code means is that the system can not communicate with the different modules in the vehicle and requires a different type of scanner. Bottom line. U need to take it to the dealer.
