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.
