Brake Pressure Modulator Valve (BPMV) Replacement (w/o JL4)

Removal Procedure

Important: The area around the electric hydraulic control unit (EHCU) MUST be free from loose dirt to prevent contamination of disassembled ABS components.

1. Thoroughly wash all contaminants from around the EHCU.

2. Disconnect the 3 electrical harness connectors from the electronic brake control module (EBCM) (1).

Important: Make sure that brake lines are tagged and kept in order for proper reassembly.

3. Disconnect the brake lines from the brake pressure modulator valve (BPMV) (2).
4. Remove the bolts (4) securing the EHCU mounting bracket (3) to the frame rail (5).
5. Remove the EHCU from the vehicle.

6. Remove the bolts (4) securing the BPMV (1) to the EHCU mounting bracket (3).
7. Disconnect the 2 way ABS pump motor connector.
8. Remove the 4 T-25 TORX bolts from the EBCM (2).
9. Remove the EBCM (2) from the BPMV (1). Removal may require a light amount of force.

Important: Do not reuse the EBCM mounting bolts. Always install new bolts.

10. Clean the EBCM to BPMV mounting surfaces with a clean cloth.

Installation Procedure

Important: Do not use RTV or any other type of sealant on the EBCM gasket or mating surfaces.
1. Install the EBCM (2) onto BPMV (1).

Notice: Refer to Fastener Notice in Service Precautions.

2. Install the four EBCM bolts.

Important: Do not reuse the old mounting bolts. Always install new EBCM bolts with the new BPMV.

Tighten the 4 bolts to 5 Nm (39 inch lbs.) in an X-pattern.
3. Connect the 2 way ABS pump motor connector to the EBCM.
4. Install the BPMV (1) to EHCU bracket (3).
5. Install the BPMV (1) to bracket retaining bolts (4).
Tighten the bolts to 9 Nm (7 ft. lbs.).

6. Install the EHCU to the vehicle frame (5).
Tighten the three EHCU bracket bolts (4) to 25 Nm (18 ft. lbs.).
7. Connect the 2 electrical harness connectors to the EBCM (1).

Important: The brake pipes are held in place by a plastic bracket mounted to the frame. Make sure that the brake pipes stay in the correct place for proper reassembly.

8. Install the 5 brake pipes to the BPMV (6).
Tighten the brake pipe fittings to 25 Nm (18 ft. lbs.).
9. Bleed the brake system.

Dealer says I need new abs module. Is that the same as an abs modulator valve? Should any other parts be replaced at time of repair.

Hello, I'm Danny
Here is a You Tube video made for our site for you to view.

I've attached picture steps below as well show abs module replacement for your Suburban. You might have to have the abs module re-calibrated with a professional scan to for correct tire size. Hope this helps and thanks for using 2CarPros.

2 nights ago, my brake petal was easier to push than normal and I had to push down on the brake petal a little harder than I usually do in order to stop. My brake light came on. I pulled over, stopped the car, started it back up again, and everything was normal.

Today, I saw a puddle of oil under the driver side of the engine. It was clear oil and cool (I've been driving for an hour). After examination, I've found where the leak is coming from, but I don't know what this part is.

I've attached some pictures of it. It sits in front of the master cylinder.

Can this be repaired? Should it be replaced? What is this part called?

Ok, thanks

that is the hydraulic portion of the abs controller. It will have to be replaced as the unit is not servicable.

Thank you Roy.

Is there a specific part or name for me to look up? I was searching for an abs hydraulic unit and what keeps showing up is a brake booster.

That's a little pricey. Is it possible to just replace the abs pump and keep the abs module controller? Or is this something that I need a completely new set?

When I google the part, I see that it can be sold separately.

This looks like the top half:
