Service bulletins for the 2010 Toyota PRIUS

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

T-SB-0064-10 Rev2018-04-23. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. Flash reprogramming allows the ECU software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Techstream ECU flash reprogramming process and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard (CUW). Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU?s information.

If the operator attempts to ready-on or start the vehicle while there is tension on the steering lock actuator, it will not be able to fully disengage when the "ENGINE START STOP" or "POWER" switch is depressed. This condition will cause the "ENGINE START STOP" or "POWER" switch's LED to flash green and the vehicle will fail to ready-on or start.
T-SB-0229-12_Rev2018-04-23. Service bulletin. ELECTRICAL SYSTEM. TSB: REVISION NOTICE November 22, 2017 Rev1: ? Applicability has been updated to include 2014 ? 2018 model year vehicles. Any previous printed versions of this bulletin should be discarded. In the event that a Toyota vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries. This bulletin is intended to assist with safe handling and inspection of flood damaged vehicles and to provide basic guidance on likely needed repairs.

ZE3_WEP_Dealer L2017-08-01. Service bulletin. ELECTRICAL SYSTEM; HYBRID PROPULSION SYSTEM: INVERTER. Dealer Letter: In our continuing efforts to ensure the best in customer satisfaction, Toyota is announcing a Warranty Enhancement Program to extend the warranty coverage for repairs related failure of the Intelligent Power Module (IPM). The vehicles covered under this Warranty Enhancement must first have Safety Recall E0E (launched in mid-February, 2014) performed (if applicable). In these vehicles, Toyota has received some reports where the Intelligent Power Module (IPM) located inside the inverter assembly of the hybrid system may fail. This condition is indicated by hybrid system diagnostic trouble codes (DTCs): P0A94, P324E, P3004, and/or P0A1A. If one or more of these DTCs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter fail safe mode. Although the Hybrid Inverter assembly is covered by Toyota?s New Vehicle Limited Warranty for 8 years or 100,000 miles (whichever occurs first), we at Toyota care about the customers? ownership experience. Toyota is now extending the warranty coverage for repairs related to failure of the Intelligent Power Module (IPM).
