• Q: How to replace the ABS Control Module on 2001 Buick LeSabre?

  A: Begin the ABS Control Module replacement task by switching off the ignition while lifting the vehicle's height. It is important to eliminate the left front wheel while eliminating the corresponding left front wheelhouse extension before you begin so loose dirt will not contaminate the ABS Control Module or any parts from the ABS system. The ABS Control Module connector position assurance needs to be taken out of the ABS Control Module electrical connector after the ABS Control Module tab rotates up to the unlocked state while workers eliminate contaminants from the ABS Control Module area completely. The user must never perform wiring harness connections or disconnections from the ABS Control Module with active ignition switch power. Unplug the ABS Control Module electrical connector from its ABS Control Module base then disconnect the Brake Pressure Modulator Valve (BPMV) electrical connector from the ABS Control Module portion. Disassemble the 6 ABS Control Module to BPMV screws before cleaning the ABS Control Module/BPMV assembly surface despite the fact that ABS Control Module repairs are not possible since this component requires replacement when faulty occurs. The ABS Control Module needs to split off from its attachment to the BPMV. The seal surface of the BPMV requires cleaning before installing the ABS Control Module directly to the BPMV while using 6 ABS Control Module to BPMV screws that require 3.2 Nm (28 inch lb) torque. Cable the BPMV electrical connector to the ABS Control Module system with the ignition switch in OFF position while performing this step. Fit the ABS Control Module connector position assurance to the ABS Control Module electrical connector first and then rotate the ABS Control Module connector tab down to its locking position. After installing both components reposition the front left wheelhouse extension along with left front wheel before allowing the vehicle to lower itself. A nonprogrammed ABS Control Module has the potential to produce inoperative or malfunctioning DRP/ABS/TCS/VSES/TIMNES (if equipped) systems while triggering DTC C1248 for the red brake warning indicator or DTC C1255m3 for internal ABS Control Module failure. When installing a new ABS Control Module for the system an updated software matching vehicle specifications must program the part and a scan tool should erase DTCs ahead of ABS Diagnostic System Check execution.
