They should be able to get a reading from any 'working' sensors and thereby identify the good ones.

"Greetings", I'm wondering if any SC430 owners have had difficulty resetting their TSMP light after replacing the tire sensors. Discount tire replaced my (2002) 4 sensors with OEM equivalents and I found a tech with the Toyota software to register the new ID's on the cpu. However, I can't get the warning light to turn off. I've tried disconnecting the battery and holding down the glove box button for 2/tire sets and failed to turn off the light. I saw a U-tube equipment seller mentioning that Toyota/Lexus can need the 'unlock' feature on their equipment to allow registering the new ID's in the system. My tech said he's never heard of such a need and he's done many resets. I'm hoping to find a not well known nuance for the original SC series that could be the missing link. Thanks for any thoughts on the subject. Max

Discount can replace the sensor BUT they don't have Toyota's TIS Techstream software system to register the new sensor with your car's electronics. Can anyone explain the 4-color code system for the wheel sensor's? I believe each color represents a different wheel but I don't know if they are specific to each 'location' on the car? I'm guessing it could possibly be a different communications frequency to denote the wheels location??
