2000 GMC Savana 3500 Parts Questions & Experts Answers

• Q: How to service and repair the ABS Control Module on 2000 GMC Savana 3500?

  A: A vehicle service and maintenance process on the ABS Control Module (ABSCM) begins with proper vehicle lift and secure support. Start the ABSCM work by removing the shield bolts of the Electro-Hydraulic Control Unit (EHCU) followed by removing the shield and separating the four electrical connectors from the ABSCM. Close inspection must be taken when removing the EHCU bracket from its mounting points because you should never bend the EHCU's brake pipes. The ABSCM needs to be disconnected from the BPMV by removing its four T-25 Torx bolts while disturbing the ABSCM module the least to prevent damage. Follow cleaning of the BPMV with a soft dry object. Replacement of corrosion-damaged or broken mounting bolts for the new ABSCM installation must be done with fresh hardware while eliminating the use of any RTV or sealants on ABSCM gasket areas. Screw the ABSCM onto the BPMV with the provided four ABSCM bolts while tightening each one to 5 Nm (39 inch lbs.) according to an X-pattern. The four electrical connectors should be connected to the ABSCM followed by shield reinstallation with three bolts tightened to 12 Nm (8 ft. lbs.). The vehicle's height should be lowered while the tire calibration needs to be updated by using a Scan Tool before moving back to the diagnostic system check.
