Need help with TPM programming of tire pressure sensors

[tomp]

Hi, when trying to program the TPM system, the manual states that the DIC diplay should still be flashing after receiving the horn-honk on the 4th tire. I am able to get all 4 TPMs to cause the horn honk in much less than the 5 minutes allowed, but when I return to the drivers seat, the TPM warning lights are no longer flashing. Please help...
