U0155 on Toyota by model: symptoms, diagnosis and fix
On 2025-2026 Camry Hybrids built with the smaller 7-inch combination meter (LE, SE and Nightshade grades - the XLE/XSE 12.3-inch cluster is not covered), the instrument cluster display can fail during vehicle startup. The failure is not limited to the display itself: because the meter software also arbitrates several body functions, a failed startup deactivates the turn signals, the hazard flashers, the seat belt warning system and the smart key reminder buzzer. Toyota reported the vehicles non-compliant with FMVSS 101 (Controls and Displays), 108 (Lamps and Reflective Devices), 114 (Theft Protection and Rollaway Prevention) and 208 (Occupant Crash Protection). Roughly 508,000 US vehicles are involved, built from August 2024 through June 2026. This is a separate campaign from the earlier 25V595 instrument-panel recall, which covered the 12.3-inch panel losing the speedometer, brake and tire-pressure telltales.
Common Symptoms
- Instrument cluster completely blank when the car is started
- Turn signals do not flash
- Hazard flasher button does nothing
- No seat belt reminder chime
- No smart key / key reminder buzzer when exiting
- Speedometer and warning telltales missing
How to Fix
Free recall repair: Toyota dealers reflash the combination meter software. Toyota's internal recall numbers are 26TB16 and 26TA16; owner notification letters were mailed September 28, 2026. Check the VIN at a Toyota dealer or through NHTSA before assuming the car is clear, since the fix is software-only and can be done in a single short shop visit. If the cluster goes blank while driving before the update is performed, treat the car as having no turn signals or hazard lights and use hand signals until it is repaired.

NHTSA recall 25V595 and Toyota campaigns 25TB08/25TA08 cover certain model-year 2025 Camry vehicles equipped with affected 12.3-inch combination-meter software. Toyota reported 49,865 potentially involved Camrys produced April 2 through November 22, 2024. Improper programming repeatedly writes unnecessary data to memory, which can cause the display to remain blank at ignition on. If driven in that state, vehicle speed and warning indications such as brake-system or tire-pressure information may be missed, increasing crash or injury risk. Production dates alone do not establish that a particular VIN is included.
Common Symptoms
- 12.3-inch combination-meter display remains blank at ignition on
- Vehicle speed is not displayed in the instrument panel
- Brake-system or tire-pressure warning information may be missed
How to Fix
Check the VIN at Toyota's official recall lookup or with a Toyota dealer. For an involved Camry, the dealer updates the combination-meter programming free of charge; Toyota also made the update available over the air for certain non-PHEV vehicles that support it. Confirm recall completion by VIN. If the display is blank, use the redundant center-screen information where available, avoid unnecessary driving, and arrange the recall remedy rather than replacing or purchasing the cluster.
Owner tips & cautions
- WarningApplicability is VIN-specific. A 2025 model year or production date inside the reported range does not by itself prove that the recall is open on the vehicle.
- TipHave a Toyota dealer or the official Toyota recall lookup confirm both VIN inclusion and completion of the free combination-meter software update.

NHTSA recall 25V595000 covers the 2025 Camry. Toyota identified an error in the instrument panel software that occurs at vehicle startup and can leave the panel failing to display vehicle speed, the brake system warning light, and the tire pressure warning light. The everyday consequence for a Camry driver is that you may set off on a commute with no speedometer indication and with two safety telltales that cannot warn you — a brake system fault or a low tire would go unannounced in the cluster. NHTSA's consequence statement is that an instrument panel that does not show critical information can increase the risk of a crash or injury. The recall's count of 591,377 vehicles covers the whole campaign across many Toyota and Lexus models.
Common Symptoms
- Vehicle speed missing from the instrument panel after startup
- Brake system warning light does not display
- Tire pressure warning light does not display
How to Fix
Free of charge. Non-plug-in vehicles, including the 2025 Camry, receive an over-the-air update to the instrument panel software; if the OTA update does not apply, a dealer can perform it. Toyota mailed the first owner letters December 5, 2025, and further letters were planned for May 2026 because the recall is phased. Verify your VIN at nhtsa.gov/recalls to confirm coverage and whether the remedy has been completed on your car. Toyota customer service is 1-800-331-4331; the campaign numbers are 25TB08 and 25TA08.

Frequently asked questions
What does U0155 mean on a Toyota?
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 Toyota it is documented across 1 model: Camry.
What are the most common causes of U0155?
The most common causes of U0155 are: 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. The specific cause varies by vehicle.
How much does it cost to fix U0155 on a Toyota?
Repair costs vary widely with the root cause and Toyota model; each issue on this page carries its own estimate where one is published.
