This is probably the mileage countdown that caused this. The car is expecting new sensors to be installed before it can be reset. Remove the front sensors and short the connector with a very small (20gauge) wire.
Now turn on the dash (secondary position or start car). Make sure clock is visible on dash, then push and hold trip meter reset button. After yellow triangle appears use up down toggle on turn single lever to scroll to the front brakes. Then push the BC button and it will ask if you want to reset. Push and hold the BC button and it should reset the mileage countdown.
I am not sure, but you may have to do the rear as well. Once you are finished you can reconnect the old sensors and you should be good to go.
