U0423 Invalid Data Received From Instrument Panel Cluster Control Module

The instrument cluster does more than display: it sends outside temperature, display and chime status or confirmations from its menus to other units. U0423 marks cluster frames that arrive but fail the receiver's checks. In GM's 2025 driver assistance controller EOCM3, 8 of 10 bad frames on chime state, display status or speed limit confirmations set a Special Type C fault that turns adaptive cruise off. Volkswagen's 2014 Touareg book has the engine controller log U0423 when the cluster still reports the ambient temperature start value FEh. Toyota's T-SB-0270-17 for the 2017 iA lists U0423 in the ABS with U0323 and U3000 when battery or display was disconnected; TPMS and TCS/DSC lamps stay on. Honda saw U0423-68 with an auto high beam message on the 2017 CR-V. Ford's 2014 list marks it MIL. U0155 is lost contact.

Likely causes

Battery, fuse or display disconnected so the cluster sends start values
Software fault in cluster or receiving module
Another node on the same bus disturbing the cluster's messages

Symptoms

  • Stability, tire pressure or assistance warnings that cannot be cleared
  • Adaptive cruise or auto high beam unavailable
  • Check engine light on some makes
