U0155 means: lost communication with the instrument panel cluster (IPC) control module.[1][2] Kia has 6 documented faults that can trigger it, across 6 models, including Kia Niro II, Kia Sorento IV, Kia Sportage V and Kia Stonic. Only a diagnosis can confirm the cause on your car.

Documented Kia faults that can trigger U0155

Grouped by engine or model, from most to least important. These are faults with the instrument cluster: not all of them will necessarily set the code, and only a diagnosis confirms the cause on your car.

Common causes of U0155 on any make

From most to least likely, according to the sources.

  1. 1Blown fuse or a power or earth problem at the cluster.[1][3]
  2. 2CAN wiring to the cluster that is damaged, broken, shorted or corroded.[1][3]
  3. 3Cluster connector with corrosion, water or a loose pin; Carista adds that it can happen after a coolant leak or water getting into the dashboard.[1][3]
  4. 4Internal fault in the instrument cluster or its transceiver.[1][3]

What to check first

The first diagnostic steps, from the most likely and cheapest to check to the most expensive.

  1. 1Scan all modules. If U0155 appears alone, it points to the cluster's power, earth or wiring; if there are many U codes, it points to a common bus or gateway fault.[3]
  2. 2Check the battery and charging before going further: low voltage generates false communication codes.[3]
  3. 3Verify the cluster's fuses, power and earth.[1][3]

Frequently asked questions

Which Kia models have faults that can trigger U0155?

Kia Niro II (1 fault), Kia Sorento IV (1 fault), Kia Sportage V (1 fault), Kia Stonic (1 fault), Kia Carens IV (1 fault) and Kia Sorento II (1 fault). Each fault has its own page with the affected years and versions, the symptoms and the repair cost.

What does code U0155 mean on a Kia?

Lost communication with the instrument panel cluster (IPC) control module. The other control units no longer receive the periodic messages from the instrument cluster over the CAN network: the cluster has "gone silent" on the network, whether through lack of power or earth, broken wiring or an internal fault. It is a generic OBD-II code: it means the same on a Kia as on any other make.[1][2][3]

Can I keep driving with U0155?

Garage soon. AutoDTCs considers it high severity and advises against driving because the speedometer, fuel gauge and warning lights are lost; Carista classes it as medium. It should be diagnosed before you depend on the car.[1][3]
