DTC B2251-01: Back Door Closer Switch General Electrical Failure [11/2024 - ]: Description
WARNING: This page is about a different car, the 2025 Toyota RAV4 and 2024 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The back door closer is controlled by the multiplex network door ECU.
The multiplex network door ECU determines the latch position of the back door lock with courtesy light switch assembly based on the combination of signals from the latch switch built into the back door lock with courtesy light switch assembly, back door courtesy switch, sector switch (home position switch) and pawl switch.
This DTC is stored when the back door closer control is being performed and it stops due to the pawl switch or door courtesy switch signal being stuck ON.
