What is a Toyota Venza AGV15 airbag control unit?
The Toyota Venza AGV15 airbag control unit is the heart of the occupant restraint system (SRS) and continuously monitors sensors to precisely deploy airbags and seatbelt pretensioners in an emergency. It ensures the functionality of all safety components and stores important crash data for accident analysis, essential for your safety.
This central electronic control unit, also called the Airbag Control Module, is responsible for real-time monitoring of the vehicle's sensors.
Its main task is to evaluate acceleration and collision data in order to activate the appropriate protective measures in the event of an accident.
Why is Toyota Venza AGV15 airbag control unit repair often necessary?
A Toyota Venza AGV15 airbag control unit repair is often required when internal components fail, communication errors occur, or there are power supply issues. It also needs to be inspected and possibly replaced after an accident, as it stores unique deployment data, making replacement or professional repair inevitable.
Aging, moisture or electrical surges can damage the internal circuits of the control unit and cause failure.
In addition, older Toyota Venza models were recalled due to problems with the door wiring, which could indirectly lead to malfunctions in the airbag system.
A faulty airbag control unit often signals problems with an illuminated airbag warning light on the dashboard, which requires immediate diagnosis at the workshop.
Common error codes for Toyota Venza AGV15 airbag control unit repair
During Toyota Venza AGV15 airbag control unit repair, specific error codes often occur, indicating communication problems or initialization issues within the control unit. These codes, such as B1000 and B1643, are crucial for an accurate diagnosis and understanding why a repair or replacement is necessary.
- **B1000** → Control unit communication error → Communication malfunction between airbag ECU and other systems.
- **B1643** → Side Satellite Sensor Bus Initialization Error → The airbag control module cannot correctly initialize the side satellite sensor bus on the driver's side.
The error code B1000 indicates a general problem in the data transmission, often caused by internal control unit errors or defective wiring.
B1643 is specific to the Toyota Venza and may be related to known recall issues with the door wiring that prevent the control module from properly initializing the sensors.

For the Toyota Venza AGV15 airbag control unit repair, various part numbers are relevant, ensuring compatibility with specific model years and trim levels. Common numbers include 89952-35011, 891700T030, and 8971048020. A thorough check with the VIN is essential for an exact fit.
The most commonly used part numbers for the Toyota Venza airbag control unit are:
- **89952-35011** | Toyota | Genuine | Fits 2009-2017 Toyota Venza models.
- **891700T030** | Toyota | Alternative | Listed for model years 2012 and 2013.
- **8971048020** | Toyota | Original | Another Genuine Toyota Part number for the Venza.
When purchasing a replacement part for a Toyota Venza AGV15 airbag control unit repair, the part number of the defective module should be exactly matched to ensure compatibility.
Technical specifications and compatibility of the Toyota Venza AGV15 airbag control unit
The Toyota Venza AGV15 airbag control unit is designed as an SRS airbag control unit that enables real-time monitoring and control of the airbag and seatbelt pretensioner systems. It is primarily compatible with Toyota Venza AGV15 models from 2009 to 2022 and offers comprehensive diagnostic functions for system integrity, essential for any successful repair.
This module integrates signals from acceleration and collision sensors, seat occupancy sensors and airbag switches.
It is crucial for the deployment of side and curtain airbags as well as frontal airbags and fits models with a 2.7 liter engine and all-wheel drive (4WD).
The built-in self-diagnosis function automatically detects errors and activates the airbag warning light if necessary, allowing prompt diagnosis by a qualified workshop.
Installation position and special features of the Toyota Venza AGV15 airbag control unit
The Toyota Venza AGV15 airbag control unit is strategically located in the center of the vehicle, usually under the seat or in the center console, to ensure optimal protection and connectivity to all airbag components. A special feature of the repair is the necessary reprogramming or VIN coding by a Toyota dealer after replacement, as each module is coded specifically for the vehicle and contains safety data.
The connectors are standardized and enable integration with all relevant sensors and the on-board network.
In models from 2009 to 2015, previous recalls have revealed problems with the wiring in the driver's door area that can affect the function of the control unit.
Since replacement modules are often used and tested, reprogramming to the individual vehicle VIN is a critical step after a Toyota Venza AGV15 airbag control unit repair to ensure full functionality and safety.
