Programming TPMS - How do I get two horn chirps instead of just one chirp?

[IGot2P]

I simply cannot get into Learn Mode simply because I only get one horn chirp instead of two. What is my problem and what do I do to correct it?

What procedure are you following to get into Learn mode?

What procedure are you following to get into Learn mode?

Just putting the car in accessory mode, closing the door, and pressing lock and unlock at the same time on my fob (I have tried two fobs). I only get on chip from the horn rather than two. Even though I only get one chirp I still have tried going to the left front wheel/tire and holding a magnet close to the valve stem to see if I might get a chirp from there but no luck. I have tried three different magnets in several different locations but still no job. If I try the lock/unlock with the car in the "on" position I do not get any chirps. I have got to "Tires" on my Tech 2 and if shows "learn" but there is no "lean" button to push. Well, that was probably as clear as mud.

That’s interesting. According to the doco, you are correct, with car in ACC, hold lock+unlock until two horn beeps. I am wondering if you need the Fob to be Fob 1?

I appreciate your prompt reply but the main fob that I tried is Fob #1 and then I tried Fob #2 so that idea is kind of out the window. I thought maybe the batteries in the sensors were dead but that would not stop the horn from chirping twice. I put new wheels on the vehicle but I don't know if the psi was registering before or not. I obviously would know more if I could get into "learn" mode which I can't.
Don (awaiting your next idea)

Ah, drat. Was afraid that was already the case. I’m hoping someone else chimes in here, but in the meantime I believe tech2 can also initiate learn mode, I’ll see if I can find the steps. I’ve not had to learn TPMS on this car yet so this will be a learning experience for me too haha
