U0155 on Chrysler
Lost Communication with Instrument Cluster
U0155 on Chrysler vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 1 Chrysler model — most commonly on Crossfire. This is a network communication code meaning a control module (usually the engine or body computer) has lost communication with the instrument cluster over the vehicle's data bus. Modern vehicles share information between modules over a network (such as CAN), and the cluster both displays data and relays messages. When messages from the cluster stop arriving, this code sets. You may see warning lights, dead or erratic gauges, missing displays, or other modules acting up. It usually points to wiring, power/ground, or the cluster itself rather than the engine. Typical repair costs on Chrysler range from $100 to $800, depending on the specific model and root cause.
Common Causes of U0155
- •Faulty instrument cluster
- •Loss of power or ground to the cluster
- •Damaged or corroded CAN bus wiring
- •Loose or corroded connectors at the cluster
- •Blown fuse feeding the cluster
- •Short or open on the communication bus
- •A different failed module dragging down the bus

Chrysler Crossfire(1 issue)
- SAM (Signal Acquisition Module) Water Intrusion2004-2008
The SAM module (Mercedes-sourced body control module) located in the trunk area suffers from water intrusion causing corrosion of circuits. This triggers random electrical faults including lighting, power window, and central locking failures.

What does U0155 mean on Chrysler?▼
U0155 stands for "Lost Communication with Instrument Cluster."
