U0155 on Jeep
Lost Communication with Instrument Cluster
U0155 on Jeep vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. 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 Jeep range from $150 to $600, 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
U0155 on Jeep by Model
Jeep Wrangler(2 issues)
- JK Instrument Cluster Gauge Needle Sticking & Cluster Failure2007-2010
Early JK Wranglers commonly develop instrument-cluster faults: speedometer, tach, fuel, and temp needles that stick, read erratically, or drop to zero, and in some cases full cluster/CCN module failure. Owners report needles losing their retaining adhesive on the stepper-motor shafts. A high-demand JK electrical search.
- Instrument Panel Cluster Internal Short Circuit and Total Cluster Failure (Recall 24V652 / 30B)2024
Chrysler recalled 32,863 vehicles — 2018-2024 Wrangler and 2020-2024 Gladiator — because the instrument panel cluster can develop an internal short circuit and fail outright, taking the speedometer, fuel gauge, and every telltale and warning lamp with it. NHTSA classified this as a failure to comply with FMVSS 101, 'Controls and Displays.' Unlike a software-blanking fault this is a hardware defect inside the cluster, and the declared remedy is replacement, not a reflash. Owner notification letters went out between October 3, 2024 and January 23, 2025.
