Lost Communication With Instrument Panel Cluster (IPC) Control

The powertrain control module (PCM) continuously monitors the controller area network (CAN) for messages from the Instrument Panel Cluster. The U0155 code sets when the PCM does not receive the instrument panel cluster message within the defined amount of time.

Cause:
Communication error
Faulty Instrument Panel Cluster
Instrument Panel Cluster harness is open or shorted
Instrument Panel Cluster circuit poor electrical connection

Symptoms:
Check engine light
