U0155 on Jaguar
Lost Communication with Instrument Cluster
U0155 on Jaguar vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 3 Jaguar models — most commonly on I-PACE, S-TYPE, XJ. 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 Jaguar range from $200 to $1,500, 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 Jaguar by Model
Jaguar I-PACE(1 issue)
- 12V Auxiliary Battery Drain2019-2025
The I-PACE suffers from excessive 12V auxiliary battery drain when the vehicle is parked. Multiple electronic modules fail to enter sleep mode properly, drawing power continuously from the 12V system. A dead 12V battery prevents the high-voltage system from activating, leaving the car completely immobilized.
Jaguar S-TYPE(1 issue)
- Electrical System Gremlins and Module Failures2000-2008
The S-TYPE is notorious for electrical gremlins caused by moisture ingress into control modules and poor CAN bus connections. Phantom warning lights, inoperative features, and intermittent faults across multiple systems are common and difficult to diagnose without dealer-level equipment.
Jaguar XJ(1 issue)
- Electrical Gremlins from Body Control Module Issues2004-2012
The XJ suffers from cascading electrical faults caused by body control module (BCM) software glitches and CAN bus communication errors. Phantom warning lights, inoperative features, and intermittent failures across multiple systems are common, especially after battery disconnection or jump-starting.

What does U0155 mean on Jaguar?▼
U0155 stands for "Lost Communication with Instrument Cluster." 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. On Jaguar specifically, this code is documented across 3 models.
What causes U0155 on Jaguar vehicles?▼
