2004 Cadillac DeVille ABS Control Module Parts and Q&A

• Q: How to replace the ABS Control Module on 2004 Cadillac DeVille?

  A: Safety first involves maintaining a warning system by avoiding touch-up attempts on the brake pressure modulator valve assembly which requires complete replacement and avoiding screw alterations except the ebcm screw. Clear the following installation procedure by first powering off ignition then locking up the vehicle and dismounting both the left front wheel together with the left front fascia extension and front air deflector. Clean the surroundings of the ebcm/bpmv before disconnecting both the ebcm connector position assurance and ebcm electrical connector. The technician should safeguard against brake fluid contact damage and must shield the vehicle body from any fluid leakage. Disassemble the bpmv by unfastening its 2 master cylinder brake pipes and 4 wheel brake pipes then drain the brake fluid from the pipes. Remove the 2 bpmv bracket nuts until the ebcm/bpmv assembly separates from the bpmv bracket. Removal of the ebcm electrical connector requires disconnecting it from the ebcm device. The 6 ebcm to bpmv screws require removal before replacing an ebcm unit with faulty components. Installation requires cleaning the bpmv seal surface before attaching the ebcm to the bpmv while using 6 screws that need to be tightened to 3.2 nm (28 inch lbs.). Install the ebcm/bpmv assembly to the bpmv bracket after placing all 3 rubber isolators correctly then tighten the 2 bpmv bracket nuts to 10 nm (89 inch lbs.). Verify proper installation of brake pipes as well as their correct connection to the pipe fittings to stop any brake fluid leakage. Every new bpmv requires removal of shipping plugs before fastening both master cylinder and wheel brake pipes to the bpmv at 15 nm torque (11 ft. Lbs.). Reinstall the ebcm electrical connector into the ebcm while locking the connector tab then apply the connector position assurance. Reestablishment of components must begin with the left front fascia extension and front air deflector and left front wheel before vehicle lowering and consecutive auto bleed procedure and abs diagnostic system check.
