U0155 on Lincoln
Lost Communication with Instrument Cluster
U0155 on Lincoln vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 1 Lincoln model — most commonly on Nautilus. 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.
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
