2002 Cadillac DeVille Parts Questions & Experts Answers

• Q: How to replace the ABS Control Module on 2002 Cadillac DeVille?

  A: You must start by turning OFF the ignition followed by raising the vehicle before attempting ABS Control Module replacement. Separate the left front wheel and left front fascia extension but maintain cleanliness of the ABS Control Module area to stop ABS component contamination. Clean all contaminants away from the ABS Control Module before removing its connector position assurance piece. Then rotate the tab on the ABS Control Module connector towards the unlocked position. Separate the ABS Control Module electrical connector from its ABS Control Module location as well as the electrical connector of the BPMV motor harness pigtail from the ABS Control Module unit. Scrape off the 6 screws which connect the ABS Control Module to BPMV before proceeding to clean both the ABS Control Module/BPMV assembly. Note that replacement of the ABS Control Module will be necessary if it proves faulty. Properly remove the ABS Control Module unit before you detach it from the BPMV. Clean the seal surface of the BPMV first before installing the ABS Control Module on the BPMV by tightening 6 screws to 3.2 Nm (28 inch lbs.). Route both the ABS Control Module connector electrical pigtail of the BPMV pump motor to the ABS Control Module followed by connecting the ABS Control Module electrical connector to the ABS Control Module unit. Follow these installation steps: Set the ABS Control Module connector tab toward the bottom position and apply the ABS Control Module connector position assurance onto the electrical connector of the ABS Control Module. Install the left front fascia extension but keep the left front wheel until the vehicle reaches the ground. The unprogrammed ABS Control Module results in failure or impaired operation of DRP/ABS/TCS/VSES/VES systems (if present) while activating the red brake warning indicator through the ABS Control Module and generating DTC C1248. Simultaneously, the ABS Control Module triggers DTC C1255m3 for internal failures. A new ABS Control Module replacement needs to receive programming software matching the vehicle specifications before installation and dealers should handle this programming process. The system check requiring a scan tool includes clearing DTCs with subsequent performance of an ABS Diagnostic System Check.
