Genuine Toyota factory central SRS airbag restraint system crash data control module computer, explicitly sourced from a Toyota Sienta. If your Sienta has a persistent airbag dashboard warning light, active diagnostic trouble codes indicating an unresolvable internal control module memory error, or a permanent software lock from a previous minor deployment, swapping out the failed hardware controller allows your technician to cleanly rebuild the vehicle safety network loop.

Fitment note: Sourced from an original factory Toyota Sienta. Please cross-reference your original module’s stamped faceplate sequence (89170-52P00 / Denso Model: 150800-3961 / Variant Designation: L4) to ensure an exact hardware matrix and software calibration match for your vehicle's safety equipment tier.

⚠️ Important Safety Installer Note: Because the airbag module holds sensitive vehicle-specific structural geometry maps and unique configuration parameters, it must be installed while the vehicle battery is fully disconnected. It will require standard factory-level calibration sequencing or standard VIN coding to seamlessly pair with your Sienta's main dashboard network panel.

Warranty: 1 month warranty covering internal processor stability and peripheral safety bus transceiver communication pathways.
