  Q: How to remove and reinstall the ABS Control Module on Cadillac Catera?

  A:

  Start by turning the ignition switch off before beginning ABS Control Module removal. Open the relay center cover before separating the Engine Control Module from its spot while moving the ecm harness out of the way. Remove and place aside the lower Radiator Hose attached to the engine. The installation requires first pulling out the lock tab from the ABS Control Module harness connector followed by connector removal before disconnecting the bottom pump motor connector of the ABS Control Module. Tear out the six ABS Control Module to bpmv screws and dispose of them while avoiding any damage to the solenoid valves and seal around the ABS Control Module. Thoroughly separate the ABS Control Module from the bpmv while carefully noting the correct position of the wave springs that were between them. In the installation process, wipe down the bpmv gasket surface with alcohol and clean rag before installing two wave springs in specified areas according to their identified positioning. The ABS Control Module must be attached to the bpmv before tightening the top four mounting screws to 2.9 nm (26 inch lbs.) across an x pattern followed by torquing the bottom two screws to this value as well. Propagate the pump motor connector beneath the ABS Control Module and join the ABS Control Module harness connector while pushing the lock tab securely. Reinsert the lower Radiator Hose to the engine block before replacing the ecm into its relay center and applying the cover. Complete the a diagnostic system check - abs while in the on position with the engine shutdown.

  Q: How to replace the ABS Control Module on Cadillac Catera?

  A:

  The first step to replace the brake pressure modulator valve (BPMV) requires setting the ignition switch to off to avoid equipment damage. The power steering fluid reservoir bolt should be removed first before setting the reservoir to the side. First detach the upper Radiator Hose from engine then secure it aside before uninstalling the relay center cover to remove the Engine Control Module (ECM) while moving the ecm harness to an adjacent position. Remove the lock tab from the ebcm harness connector before disconnecting the ebtcm harness connector while taking note of the brake pipe positions for re-installation. The bpmv receives its wheel cylinder brakes and master cylinder brakes connected to it through brake pipes which need disconnecting at this point while implementing pipe plugs to maintain brake fluid content and airspace protection from contaminants. First disconnect the nuts linking the bpmv to its bracket before sliding off the heat shield from the insulator stud to relocate brake pipes safely for extracting the bpmv assembly and ebcm bracket. To replace the bpmv alone you should remove the ebcm unit from the system. Put the ebtcm inside the bpmv before inserting both parts as an assembly into the bpmv bracket. Ensure correct alignment and make sure the bpmv faces the lower insulator stud. After positioning the heat shield onto the insulator stud it is essential to install the two bpmv to bpmv bracket nuts while tightening them to 12 nm (106 inch lbs.). New installations of bpmv require users to eliminate the plugs inserted during shipping from both valve openings. The bpmv requires connections of master cylinder brake pipes and wheel cylinder brake pipes while all pipe fittings need tightening to 15 nm (11 ft. Lbs.). After disconnecting the ebcm harness connector and pushing in the lock tab you should reinstall the ecm into the relay center before covering the relay center. First reconnect the upper Radiator Hose to the engine and install the power steering fluid reservoir then perform the brake hydraulic system bleeding and fill while turning the ignition switch to on with the engine stopped before executing the diagnostic system check - abs.
