U0155 on Toyota
Lost Communication with Instrument Cluster
U0155 on Toyota vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 2 Toyota models — most commonly on Camry, RAV4. 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.
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 Toyota by Model
Toyota Camry(3 issues)
- 2025 Camry May Start With a Blank Speed Readout and No Brake/TPMS Warnings (Recall 25V595000)2025
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 591,377 units published for this recall are the total for the whole campaign across many Toyota and Lexus models.
- 7-Inch Combination Meter Goes Blank at Startup and Disables Turn Signals and Hazard Lights - Recall 26V5112025-2026
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.
- 2025 Camry 12.3-Inch Instrument Panel May Go Blank - Recall 25V5952025
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.
Toyota RAV4(1 issue)
- 2023-2025 RAV4 12.3-Inch Instrument Panel May Go Blank - Recall 25V5952023-2025
NHTSA recall 25V595 and Toyota campaigns 25TB08/25TA08 cover certain 2023-2025 RAV4 and RAV4 Prime/Plug-in Hybrid vehicles equipped with affected 12.3-inch combination-meter software. Toyota reported 113,286 potentially involved RAV4s and 33,001 potentially involved RAV4 Prime/plug-in vehicles. 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 warnings such as brake-system or tire-pressure information may be missed. Model year alone does not establish VIN inclusion.

What does U0155 mean on 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 specifically, this code is documented across 2 models.
