Q: How to Replace the ABS Control Module on GMC Yukon?
A: Raising and supporting the vehicle is the first step toward ABS Control Module replacement with part number JL4. First discard all dirt and debris from the ABS Control Module unit and brake pressure modulator valve (BPMV) before starting any component removal procedure. The installation of new screws replaces the ABS Control Module to BPMV screws because their reuse is prohibited. Denatured alcohol should be used to clean the ABS Control Module and BPMV before disconnecting the ABS Control Module electrical connector. Use caution when removing the ABS Control Module from BPMV by pulling it out after discarding both ABS Control Module to BPMV screws. Installation requires proper alignment of the ABS Control Module with the BPMV while placing the new gasket onto the BPMV and positioning the brake pressure switch without pressure on the components. Offer the ABS Control Module with square alignment to the BPMV surface before installing four new ABS Control Module to BPMV screws in an X pattern at 3 N.m torque. Plug in the ABS Control Module electrical connector. Run the programming procedures when installing a new ABS Control Module. The appropriate automated BPMV bleeding procedure must be used to finish the process.
Q: How to Reprogram and Set Up an ABS Control Module on GMC Envoy?
A: The replacement of the ABS control module requires ABS control module reprogramming through the Service Programming System (SPS) while the tire calibration needs to be revised through the Scan Tool Tire Size calibration function. The Service Programming System (SPS) becomes necessary to reprogram the ABS control module when such operation is required.
Q: How to replace the ABS Control Module on GMC Canyon?
A: Begin ABS Control Module replacement by switching off the ignition stem. Break loose and remove both the brake pressure modulator valve (BPMV) and then remove the ABS Control Module bolts. Throw out the discarded hardware. The ABS Control Module must be properly disentangled from the BPMV before you remove all 12 ABS Control Module to BPMV seals. Presentation of the ABS Control Module along with its 12 seals onto the BPMV requires attention when installation begins because all ABS Control Module bolts need replacement with new ones which should be tightened to 2 Nm (18 lb in). Install the entire ABS Control Module/BPMV assembly into the vehicle before performing an ABS Control Module programming procedure when needed.
