Use this thread for supported-model questions, 93C66 dump validation, TPX2 or EH programming results, and immobilizer-to-engine-ECU synchronization troubleshooting. Include the Toyota model and year, immobilizer part number, EEPROM size, read method, symptom and DTC, but remove VIN, key data and customer information before posting.
