• Q: How to replace the ABS Control Module on 2001 Cadillac DeVille?

  A: Users should begin the ABS Control Module replacement by turning OFF the steering wheel and lifting their vehicle. Wash and dry the surroundings of the ABS Control Module before removing the left front wheel and left front fascia extension to protect ABS components from contamination. After washing all dirty substances away from the ABS Control Module, the user should rotate the ABS Control Module connector tab to an unlocked position to detach the ABS Control Module connector position assurance from the electrical connector of the ABS Control Module. The wiring harness requires disconnecting or connecting without turning on the ignition switch to prevent damage to equipment. Use the following procedure to disconnect both the ABS Control Module electrical connector from the ABS Control Module part and release the brake pressure modulator valve (BPMV) pump motor harness pigtail electrical connector from the ABS Control Module. Plunge out the 6 ABS Control Module to BPMV screws while conducting cleaning operations on the ABS Control Module/BPMV assembly surface and understanding that replacement of the ABS Control Module unit becomes necessary if it proves faulty. Remove the ABS Control Module apart from its connection to the BPMV. Installation requires the user to clean the BPMV seal surface before screwing the ABS Control Module to the BPMV at 3.2 Nm (28 inch lbs.). Plug in the BPMV pump motor harness pigtail electrical connector to the ABS Control Module followed by connecting the ABS Control Module electrical connector to the ABS Control Module. Then install the ABS Control Module connector position assurance before rotating the ABS Control Module connector tab down to its locked position. After installing the left front fascia extension and left front wheel, replace the vehicle on its supports. The functionality of DRP/ABS/TCS/VSES (if equipped) can be impaired by an unprogrammed ABS Control Module while the ABS Control Module triggers the red brake warning indicator through C1248 DTC and displays C1255m3 DTC because of an internal malfunction. A new ABS Control Module requires programming with the current version that matches the vehicle specifications; contact your local dealer for this software programming step. The diagnostic system check with the scan tool must be completed after clearing the DTCs.
