Ce que signifie U0155
A module on the communication network has stopped receiving messages from the Instrument Panel Cluster (IPC), the dashboard gauge unit that shows speed, fuel, warnings, and other information. In practice, the gauges and warning lights may stop working or show wrong information. It is commonly caused by lost power to the cluster or a break in the network wiring.
Symptômes courants
- Dead, frozen, or erratic gauges (speedometer, fuel, temperature)
- Warning lights on or warning messages
- Dashboard display blank or not updating
- Mileage/odometer or info display not working
- Other modules reporting communication faults
Causes courantes
Classées de la plus courante à la moins courante.
- 1Loss of power or ground to the instrument cluster (blown fuse, corroded connector)
- 2Damaged, broken, or shorted CAN bus wiring to the cluster
- 3Corroded, loose, or backed-out connector pins at the cluster
- 4Another module disrupting the communication bus
- 5Failed or faulty instrument panel cluster
Que faire
Have this checked soon, because a non-working gauge cluster can hide your speed, fuel level, and important warning lights, which makes problems harder to notice. A technician should verify cluster power, grounds, and fuses and inspect the network wiring before replacing the cluster. Drive carefully if you cannot see your speed or warnings, and get it repaired promptly.
