Question

the forward collision alert system calculates and displays a following distance (in seconds) when it is tracking a car ahead. i would like to be able to read this number from the obd port. is it possible? what would the request code be?

Answer 1

It will be a while for this to be something that can be done, for now the Automatic crash response system  is under a Recall. What happened is a incorrect calibration in the software. TSB 12187C
