OBDII relearn procedure An OBDII relearn procedure requires a TPMS scan tool to transfer new sensor IDs directly to the vehicle’s ECU. The user would need to scan each TPMS sensor, connect to the vehicle’s OBD port, then follow the step-by-step instructions on the tool. The new TPMS sensor IDs are then transferred to the vehicle. Most Asian and specialty European vehicles require OBD relearn. For example, a 2010 Camry requires an OBDII relearn procedure: 1.Inflate all tires 2.Read all sensor IDs using TPMS scan tool 3.Connect tool to OBDII port 4.Reset ECU with tool 5.Turn ignition OFF, then ON 6.Drive at 12 mph for up to 5 minutes |
