• Q: How to replace the ABS Control Module on 2005 Cadillac DeVille?

  A: Turn off ignition and lift the vehicle before starting the replacement of an abs control module (ABSCM). The left front wheel and left front fascia extension must be taken off. Before working on the abscm clean its surrounding location to avoid antilock brake component contamination. Thoroughly wash every substance away which is stuck to the abscm and its surrounding area. You must rotate the tab on the abscm connector position assurance until the unlocked position becomes available to detach it from the abscm electrical connector. The wiring harness must never receive connection or disconnection while the ignition switch maintains an on position to protect equipment. Remove abscm electrical connector and brake pressure modulator valve (bpmv) pump motor harness pigtail electrical connector from their connection to the abscm. Clean the 6 abscm to bpmv screw holes before removing these screws so you can access the abscm/bpmv assemble. Repairing the abscm is impossible because a faulty unit requires new replacement. The separation between abscm and bpmv must be executed. Clean the seal surface of the bpmv before you install the abscm onto the bpmv. Fix the 6 abscm to bpmv screws while tightening them to 3.2 Nm (28 inch lbs.). The bpmv pump motor harness pigtail electrical connector must connect to the abscm while keeping the ignition switch in off position before installing the abscm electrical connector to its host. Install the position assurance while placing the abscm electrical connector under the tab rotated to its locking position. Reinstall the left front fascia extension followed by the left front wheel while lowering the vehicle. The abscm without programming will result in poor system performance of drp together with abs / tcs / vses / ves when these systems exist, while also creating the faults c1248 and c1255. When replacing an abscm users should select the latest software which matches their vehicle for programming the component. The scan tool should be utilized to eliminate stored dtcs followed by conducting the abs diagnostic system check.
