2002 Buick LeSabre Parts Questions & Experts Answers

• Q: How to replace the ABS Control Module on 2002 Buick LeSabre?

  A: The replacement of the ABS Control Module should start by shutting off the ignition followed by lifting the vehicle. Start by lifting the vehicle and removing the left front wheel together with the left front wheelhouse extension before cleaning all dirt from the vicinity of the ABS Control Module area. The ABS Control Module connector positioning assurance needs to be removed from the electrical connector while the ABS Control Module connector tab is rotated into its unlocked position after cleaning all contaminants around the ABS Control Module. The process of connecting or disconnecting the wiring harness to the ABS Control Module must be avoided when the ignition switch stays in the ON position to protect your equipment. ABS Control Module electrical connector must be separated from the ABS Control Module unit while Brake Pressure Modulator Valve (BPMV) electrical connector requires removal from the ABS Control Module device. Disassemble the 6 ABS Control Module to BPMV screws and clean the ABS Control Module/BPMV assembly surface making note of the ABS Control Module's inability to be repaired. The ABS Control Module unit must be removed from the BPMV assembly. First clean the BPMV seal surface and after that install the ABS Control Module to the BPMV while using the appropriate 6 ABS Control Module to BPMV screws with a torque setting of 3.2 Nm (28 inch lbs.). You should install the ABS Control Module connector position assurance onto the ABS Control Module electrical connector before turning the ABS Control Module connector tab down to the locked position. Reattach the left front wheelhouse extension followed by reinstalling the left front wheel and decrease the height of the car. A nonprogrammed ABS Control Module can trigger the failure or improper operation of DRP/ABS/TCS/VSES/TIM/VES when these systems are equipped and may activate DTC C1248 to display the ABS Control Module turning on the Red Brake Warning indicator or activate DTC C1255m3 for an ABS Control Module internal malfunction. A new ABS Control Module should get programmed with current vehicle software before a diagnostic system check occurs. The vehicle requires a scan tool to clear all stored DTCs before ABS Control Module programming.
