1998 Buick LeSabre V6-3.8L VIN KSECTION Service and Repair
REMOVAL PROCEDURE
Caution: Do not pry Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM). Be careful not to damage seal (If rousing module). It seal is damaged during removal, repair damaged area using GM silicone sealer or replace EBCM/EBTCM.
Important: You cannot repair the EBCM/EBTCM. If the assembly is faulty, replace the EBCM/EBTCM as an assembly.
1. Turn the ignition switch to the Off position.
2. Remove the air cleaner assembly and the Powertrain Control Module (PCM) cover.
3. Remove the EBCM/EBTCM harness connector.
4. Remove the front EBCM/EBTCM bracket from the vehicle (5).
5. Remove the EBCM/EBTCM center bracket mounting bolt (4).
6. Remove the four EBCM/EBTCM to BPMV bolts (1).
7. Remove the EBCM/EBTCM by pulling rearward until the internal connector disengages. Do not twist the assembly.
INSTALLATION PROCEDURE
Notice: Be sure to reconnect all harness retaining clips that may have been disconnected during the removal procedure in their original positions. Then perform a visual inspections of the entire harness checking to make sure all retaining clips are properly connected.
Important: When replacing the EBCM/EBTCM, you must recalibrate the Magnasteer(R).
1. Clean the EBCM/EBTCM seal and BPMV gasket surface with alcohol.
^ Tighten the four EBCM/EBTCM to BPMV bolts (1) to 4.5 Nm (40 inch lbs.).
NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.
2. Install the front EBCM/EBTCM bracket (5).
^ Tighten the EBCM/EBTCM center bracket mounting bolt (4) to 14 Nm (10 ft. lbs.).
3. Install the EBCM/EBTCM harness connector.
4. Install the air cleaner assembly and the PCM cover.
5. Turn the ignition switch to the RUN position, engine Off.
6. Perform the Diagnostic System Check.
