I trained my tires a month ago and now it wont work. I replaced one stem but none will honk now. Is there a master reset to do them again?

 

TPMs. 1) Turn ignition on 2) Press "Reset" button in order to clear any IPC display warning messages 3) Press and release the "Options" button on the DIC to scroll through the display options until the IPC display is blank 4) Press and hold the DIC "Reset" button for 3 seconds 5) Press the "Options" button again until TIRE TRAINING message appears 6) Press "Reset" button until the IPC "Learn L Front Tire" message appears in order to begin the programming 7) Install the J41760 Tire Pressure Monitor (TPM) System Programming Tool (large magnet will do) over the left front valve stem 8) The horn will sound, indicating the left front TPM sensor is programmed (if this takes more than 15 seconds, pull magnet back and try again, it will give you three tries. Then you must start over) 9) When the horn sounds, proceed to program the next TPM sensor in the following order as directed by the IPC messages: -Learn R Front Tire -Learn R Rear Tire -Learn L Rear Tire Programming can be canceled by turning ignition off, waiting 2 minutes with no sensors being learned, finishing all 4 wheels or through the DIC. If the programming is canceled with less than 4 sensors learned, it will only accept the codes programmed up to that point.flag: Take about 10 Min Hams

 

If the first sensor is dead on driver front you can't do the rest.

 

You can't program all the rest, but you can still determine if they're dead. If you can't get LF to beep the horn, you move to RF. If that doesn't beep the horn, it's dead too and you move to RR. If RR doesn't beep the horn either, it's also dead, and you move to LR. Any that beep won't program properly in the computer, but at least you'll know they're still good. Then you go get replacements for the ones that didn't produce a beep.
