Caution: For safety reasons, the brake pressure modulator valve assembly must not be repaired, the complete unit must be replaced. With the exception of the EBCM, no screws on the brake pressure modulator valve assembly may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
2. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 4.6L.
3. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
4. Clean any brake fluid spillage from the BPMV.
5. Remove the 3 EBTCM/BPMV assembly bracket nuts.
6. Remove the EBTCM electrical connector.
7. Remove the BPMV motor ground cable.

Notice: When removing the brake pressure modulator valve, protect the vehicle exterior from possible brake fluid spillage. Brake fluid can cause damage to painted surfaces.

Notice: Excessive bending of brake pipes during BPMV removal or installation may cause permanent damage that will require replacement.





Important: Note the location of the brake pipes to use as an aid during installation.

8. Remove the 6 brake pipe fittings.
9. Remove the EBTCM/BPMV assembly from the vehicle.
10. Remove the front insulator and insulator mounting bolt.
11. Remove the 4 EBTCM to BPMV bolts.

Caution: Do not pry the EBTCM from the BPMV as damage to the seal may result.




12. Separate the EBTCM from the BPMV by gently pulling forward until aspirated. Be careful not to damage the seal.
13. Clean the seal and BPMV gasket surface with alcohol.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1. Install the EBTCM to the BPMV.

Tighten

•	Tighten the 4 mounting bolts to 4.5 N·m (40 lb in).

•	Tighten the insulator bolt to 14 N·m (124 lb in).




2. Position the EBTCM/BPMV assembly in the bracket and install insulators and bracket nuts.

Tighten
Tighten the bracket nuts to 9 N·m (80 lb in).





Caution: Make sure brake pipes are correctly connected to BPMV. If brake pipes are switched by mistake Inlet vs. Outlet, wheel lockup will occur and personal injury may result.

Important: If you install a new BPMV, remove the shipping plugs from the valve openings.

3. Install the 6 brake pipe fittings, using locations noted during removal.

Tighten
Tighten the brake pipe fittings at the BPMV to 15 N·m (11 lb ft).




4. Install the EBTCM electrical connector. Ensure the EBTCM connector tab is locked down.
5. Install the pump motor ground cable connector.
6. Install the air cleaner assembly. Refer to Air Cleaner Assembly Replacement in Engine Controls - 4.6L.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

7. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
8. Fill and bleed hydraulic brake system. Refer to Master Cylinder Reservoir Filling and Hydraulic Brake System Bleeding in Hydraulic Brakes.
9. Perform the Auto Bleed Procedure. Refer to Antilock Brake System Automated Bleed Procedure .
10. Perform the ABS Diagnostic System Check. Refer to Diagnostic System Check - ABS .
