Service bulletin T-SB-0134-16

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.

NHTSA's summary

TSB: Supersession Notice. 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.

21TG01	2025-07-10. Service campaign. 21TG01 Exprired - Replaced with Campaign 23TA13 During a recent investigation of reported battery fires in 2013-2018 RAV4 vehicles with gasoline engines (excluding hybrid models), Toyota discovered that many non-Toyota retailers and others who sell or install replacement batteries were recommending a small size battery for replacement.

The smaller battery may not fit securely with the RAV4’s battery mounting parts, and, in some cases, can move around when the vehicle is driven, causing a short circuit. Using the wrong size battery, or not installing a replacement battery properly, can cause damage to the battery and the vehicle, and it could cause a vehicle fire.
