I got a 2016 LS 460 and put 20’s on it. The TPMS sensor information is registered in ECU, but will not display the information. I only get dashes. Can’t figure out what to do. Tried everything and reset too. Still won’t display. Any suggestions?

How did you registered the new TPMS, through Techstream? I registered the new TPMS through Carista app without any issue. But I was having problem registering them through Techstream.



OEM TPMS

Register to new TPMS.

I first had all dashes as well. Once I drove the car, all the numbers appeared.

Kalieb

We used Ateq

Try to drive like R Z mentioned. If you drive for 20 minutes and the lights stay on, then the new TPMS are not registered properly. When I did the registration through Carista, the car took the new TPMS right away without need to drive the car. The car was reading PSI and temps.

Make sure all serial numbers are entered correctly.

I connected to the ECU and saw the sensor data on my computer. So they are in the TPMS system, the cluster just won’t display it, only dashes.

Kuhan

Are you positive the new TPMS serial numbers were entered and not the old ones still stored there?

Kalieb

Yes, triple checked it and scanned them in with a tool. The new numbers are in, the old tires are off the car and stored

Are they stored nearby the car? I remember years ago a member having a problem and it turned out his old wheels were in the garage with the car and it caused a problem.

Were the wheels and TPMS sensors brand new? They have a radio device they use at tire shops to "wake up" the sensors, so the batteries aren't consumed before first use.

I had problems when I first tried to set up my snow wheels, and I took it to a tire shop and a guy read the codes and programmed them to my car in 2 minutes. Didn't even charge me; had to insist that he at least take a tip.

Kalieb

Did that at a shop would not work for him either

I just got my new wheels, tires, and sensors installed today and had the dashes as well. I drove for about 20 minutes and the low pressure light came on. Does this mean the new sensors weren't registered correctly?

I had the same issue, brought my car to Discount Tire where I bought the new TPMS sensors on my 07 and had them go around with their tablet and "wake" them up
this solved the problem

Kuhan

^Maybe that’s what it needs. A wake up call.

LexG

I’ll go back and see if they can do that.
