Lost Communication With Instrument Panel Cluster (IPC)
What U0155 means
U0155 means communication with the instrument panel cluster has been lost on the data bus. The cluster displays speed, RPM, warnings, and mileage, so a comm loss shows up as dead or erratic gauges and is usually a wiring, power, or cluster fault.
Symptoms
- Dead, frozen, or erratic gauges
- Warning lights stuck on or not working at all
- Blank display / no odometer reading
- Other modules reporting lost communication
Likely causes (most common first)
- CAN bus wiring fault to the cluster
- Blown fuse or bad power/ground at the cluster
- Corroded or loose cluster connector
- Low battery voltage
- Failed instrument panel cluster
Can I keep driving?
Risky — you may lose your speedometer and warning lights. Check fuses, grounds, and battery voltage, then have the cluster/bus diagnosed.
