TPMS registration

I'm trying to code a 5th TPMS sensor for a 5-wheel rotation. I've got Techstream and each time I try to code in the 4 sensors that are currently on the truck, I get an error stating:

"ID Registration failed due to a communication error with the ECU while in Initialization mode. Terminate Initialization by connecting TC and CG of the DLC3 for 30 seconds."

This message says to basically jump 2 pins in the OBD port for 30 seconds. I've tried jumping the pins for 30 seconds and then removing the jumper, and then connecting Techstream but I get the same error. Does anyone have clear info on how to get the truck out of initialization mode?

I've read this may be associated with the garbage OBD cable that you get on eBay. In another thread, @MCDavis mentioned being able to easily add sensors with the cable that was supplied with OVTune. Has anyone else been able to do this with the Mini VCI cable from eBay?

 

Correct, in my case the cable with TS lite from eBay would not write to the truck. The cable supplied with OVTune provided quick success.

I had the same error pop up and tried the clear initializaion mode via hr two pin jumper. I was able to jump he pins and clear the mode but the eBay cable would not write.

Also, I’ve not been able to get a 5th TPMS into the truck as TS Lite only provides registration slots for 4. I can’t confirm if 5 can be written to the truck as my experience with the dealer and with TS Lite only provides 4 registration slots.

 

Earlier 2nd Gens had a sensor in the spare. You can only program 4 Max to a Tacoma now.

 

Thanks. I'm looking to just do the 4 wheel TPMS by swapping the 5th ID each time I rotate, similar to what you're doing, but can't get any of my cables to write to the truck. I've got this shitty Mini VCI one from eBay, another shitty one from Amazon that works with my BMW, and I've tried to use a Dimsport MyGenius that I used to tune my BMW but I can't seem to get it to function as just a cable. If anyone knows of a decent cable for a not outlandish price let me know...

Once I figure this out I'll put together another DIY since there are others interested in this too.

 

Definitely spend a few extra bucks on a better line in. OVTune is linking to the Taxtric (spelling?) cable for his tune. The TPMS writes in 15 seconds with that cable.

 

The Tactrix is $169 for the cable (ouch) and it isn't clear that it can be used with other vehicles. Some of these cables seem to be brand-specific. I am very on the fence about OVTune though, so if I buy this cable I'll be that much closer... Thanks for your input!

 

Did you find a fix. I'm having the same issue.

 

3rd Gen Tacoma PCM/ECU does not have the ability to have/thread/store/program a 5th TPMS sensor.
There are 3rd Gen owners here that have a 5th and the TPMS system crashes.

 

Oh I was just trying to write new ids for my winter sets but it keeps giving me the same error.

 

All I use are clone Autel sensors which allow me to copy my OEM sensor ID numbers to the Autel sensors with my Autel Maxi TPMS OBDII hand tool. No programming the PCM/ECU.

 

which autel are you using?

 

TS601
