C1018 MERCURY Description
The ABS module is the main control module for the braking system including the regenerative brake system. When a new ABS module and HCU assembly are installed on a vehicle, several calibration routines must be performed using a diagnostic scan tool for the brake system to operate correctly. Certain criteria must be met for each calibration routine to complete successfully. If a calibration routine fails to complete there is a Parameter Identification (PID) in the ABS module that aids in identifying the concern that caused the routine to fail.
