    Toyota, Lexus, Scion loop mode help

    Bartec WRTRST50/Schrader 21250 TPMS System Reset Tool Instruction sheet

    NOTE* - This tool is specific to Toyota, Lexus, and Scion vehicles ONLY!

    Note** The Bartec WRTRST50/Schrader 21250 tool is to be used along with a properly formatted TPMS scan tool!

    Systems of a Toyota/Lexus Scion TPMS system to become locked in loop mode:

    If your TPMS tool gives you the error message of: "cannot WRITE the ID's to the control module" while performing a TPMS relearn on a Toyota/Lexus/Scion, the vehicle's TPMS system is stuck in a "loop mode."

    What causes a Toyota/Lexus/Scion TPMS system to go into "loop mode?"

    - If the TPMS reset switch is pressed (in those cars equipped with it) AFTER a TPMS sensor replacement and BEFORE the new sensor(S) are programmed to the Control Module by a TPMS scan tool, the vehicle can become stuck in a loop. The vehicle is searching for older TPMS IDs that are no longer there.
    - Driving the vehicle with the TPMS warning symbol on for an extended period of time.

    How to use the Bartec WRTRST50/Schrader 21250 Reset Tool
    1. Insert the Bartec WRTRST50/Schrader 21250 tool into the DLC3 (OBD port) on the vehicle.
    2. Once connected, turn the ignition to the key ON/Engine Off position.
    3. Press and hold the button on the Bartec WRTRST50/Schrader 21250 tool for at least 30 seconds.
    4. Remove the Bartec WRTRST50/Schrader 21250 tool, and resume the TPMS relearn using your TPMS scan tool.

    NOTE- The System Reset Tool does not work with Land Cruiser models

    This is a very common issue with Toyota and Lexus vehicles. Newer TPMS scan tools have a new function to reset the system without needing a separate tool!
