Cloned Autel TPMS Sensors to Original IDs, Light Still Blinking

Hey folks, had some new wheels/tire put on my '13 2nd gen TRDOR recently and the shop neglected to swap or install new TPMS sensors. Long story not worth telling. TPMS light in the dash was blinking when I picked up the truck. I got the Autel TS508 programmer and a set of Mx sensors, read the sensor IDs the truck is looking for via OBD, manually programmed the new Autel sensors with those IDs. Confirmed everything was in order by scanning the OEM sensors, 3 of which are still alive but have low voltage. They show the same IDs as the OBD reader (and I can assume the 4th would if it was alive). Scanned the new Autel sensors, they show the correct IDs. I have not had them installed in the tires yet, so I never expected the TPMS dash light to go off, but I did expect it to stop blinking if the new sensors were present. It has not stopped blinking, and long button presses on the reset button below the steering wheel are doing nothing. Truck has been driven plenty of miles with the new sensors present (and the old ones not, obviously). I don't feel like having the tires remounted to find out this isn't going to work for some reason. What am I missing? Do the sensors really need to be at pressure before they'll communicate with the truck? Thanks.

 

Anyone?

 

My guess is - Yes. they may be (probably are) communicating with the truck, but without detecting any pressure they won't turn off the light (that's what they do). One way to hack sensors is; you need a little creativity or do a web search (there are you tube videos), using a piece of 3" schedule 40 PVC, long enough to hold your TPMS sensors - cap one end, install a schrader valve, seal the other end (plumbing cap or threaded end), put sensors in tube, seal and pressurize to 40PSI - should put your light out.

 

Thanks jbrnigan. I guess I should have been clearer - at the moment I'm not trying to get the light to go off, I'm just trying to get it to stop blinking. This all assumes I understand how the tpms light behaves - blinking means there's a communication issue, like a dead sensor, and solid means low pressure). If I can get the light to go solid, I'll be confident there's communication between the truck and the sensors and go ahead and have the tires remounted, and then presumably the light will go off as soon as the tires are at pressure. But I'm just not confident that will happen since the sensors have been cloned successfully but the truck doesn't seem to see them.

 

FWIW - When I had tires replaced last year, I supplied the tire shop with replacement sensors (Denso). The shop confirmed that their programmer could read and program the sensors. My OE sensors were 7 years old and I had a solid TPMS light - so it made sense to replace all of them with the new tires. When I picked up the truck, the TPMS light was off. The next morning it was on. The tire shop suggested driving the truck for a few miles. The light went from solid on, to blinking. I went to the tire shop and they reprogrammed the sensor(s). Light has been off since.
