Programming the FG Falcon ABS module for a Turbo conversion

When converting an FG Falcon to run on a Turbo PCM, you will see DTCs from the PCM as the calibration on the ABS unit differs between models.

This guide covers how to reprogram the ABS module to suit the Turbo PCM using Forscan. You must have an Extended Licence, which can be registered for free from Forscan.org.

You’ll also need an OBD2 scan tool — Click here for a low cost VGate Scan Tool that will work with Forscan or for a Tactrix cable that will work with Forscan and PCMTec click here.
