That would suggest that you have the base model, that
ABS was an option and it was not fitted to your vehicle. See
https://fordforums.com.au/wsmpub//eflwx/2-8.html and check if it has a
ABS modulator and tone wheels fitted and the
ABS ground pin in the diagnostic connector. I suspect you will find none of these. Is it a sedan or a ute? Base model utes, being mainly sold as commercial vehicles in a more price sensitive market often had no
ABS fitted. Similarly poverty pack taxis often came sans
ABS.
This thread would also probably better fit in either this
https://fordforums.com.au/forumdisplay.php?f=20 or
https://fordforums.com.au/forumdisplay.php?f=29 this part of the forum. If you want it moved to where it might get more responses just ask.
