Hey everyone, quick question I just had my rims put on yesterday with new TPMS sensors put on, and the system light just went on what should I do? Take it back to the dealer to get the calibrated with the car? Im not so sure. Please help Thanks.

 

Check your system and see where the PSI range is set. Then check pressure in all 4 tires. If that is all inline, then maybe a bad sensor.
OR If they are 4 entirely new sensors then I'm pretty sure the ECU needs to be reset to the new sensor ID tags.

Did you have the new wheels/ sensors installed at a Lexus dealer?

 

Check the pressures and if they're all fine, bring it into the dealership tomorrow and have the senors reset to the car

 

Yup, the guys are right. The computer needs to be reset to recognize the new wheels. Had the same thing happen when they put my summer's back from my winters....quick reset by the dealer and all was good.

 

What kinda wheels did u get???

 

Since you got new TPMS sensors you need to write down the codes and take the car to your Lexus dealer, they'll program these 4 codes as a 2nd TPMS set. I did mine last week, I took the car on a Friday afternoon to the new Lexus of North Miami dealer and they were going to charge me $119 for this, I couldn't believe it! They were booked for the rest of the day so I had to make an appointment for Monday. Next morning I drove to Lexus of Kendall and asked about the same thing, they guy brought his laptop, connected it to the car, entered all 4 codes, and in 5 minutes I was all set, and free of charge!

The tech guy said that the warning light/message will pop up if tire pressure goes below 31 PSI on any tire.

 

Sort of. If you lose a little more than 5 psi from the initial setting, you'll get a light. You'll also get a light at 28 psi absolute no matter what.

If you didn't write down the codes, you can force the sensors to transmit their IDs by rapidly deflating more than 5 psi. The dealer can then enter the code with their Techstream setup.

 

most likely it was a low psi issue. i had the same issue when i had my rims set and fitted. low tire pressure, and this thing lights up in a hurry...that is one light that i didnt want on any longer. make sure you're tires are inflated to the factory setting...that should fix it.
