U0155Lost Communication With Instrument Panel Cluster (IPC) Control Module
- Generic OBD-II code · Network
- Turns on the check-engine light
- How the car detects it
- U0155 says a listener no longer receives the instrument cluster, which shows speed and warnings and on many cars also produces chimes and turn-signal ticks. The cause is not always the cluster: on 2017 GM full-size trucks and SUVs several modules logged U0155 when the serial data gateway hung, so dead gauges came from the gateway (PIT5586G). The code can also trigger the MIL. Honda's 2021 Accord and HR-V and 2022 Odyssey lit it with U0155 after the evaporative leak check, when shutdown commands between units did not match; new engine software fixed it (21-021). Ford's 2020 Explorer showed MIL and wrench lamp with U0155 and U0100 due to gear shift module software (SSM 49218). FCA writes Cluster/CCN, Saab Instrument Cluster. U0423 covers invalid cluster data, U0156 the information center.
