Instructions for removal: Kelsey-Hayes GM/GMC/Chevy, Delphi Corvette

Kelsey - Hayes

GM/GMC/Chevy

Locate EBCM unit (Below drivers door just inside frame)  Remove four T-20 torx head screws from top of EBCM.  You will need a small 1/4" ratcheting wrench and a 1/4" shallow socket to use on the T-20 torx bit.  Once the screws are out, use firm upward force to break the soft seal from the pump block. 

BE SURE TO LIFT STRAIGHT UP ON  THE MODULE UNTIL ALL 6 SOLENOID SHAFTS ARE CLEAR!!!!

Remove the three wire harnesses attached to the EBCM.  Once the module has been removed, cover the pump block with plastic and secure with duct tape to keep debris out.

The diagram below is to visualize the location of the ABS module (1) ONLY, do not remove the pump assembly (2) and pump assembly bracket (3) from frame.  If you do need to remove the pump assembly, be sure you know what you are doing and know the brake bleeding procedure upon installation.

It is safe to move the vehicle without the ABS unit attached. Your vehicle reverts to conventional brakes when the ABS system is innoperable.

In Addition there will be no loss of brake fluid at all...

Delphi/Corvette EBCM removal...

The procedure for removing the EBCM is very simple. The only special tool you need is a T-20 torx screw driver. A tool set that has a 1/4" drive screwdriver with an adapter for many different size bits. A flathead screwdriver may also be needed to pry apart the EBCM from the BPMV

1 - Make sure the car is off.
2 - You will probably need to remove the airbridge to get to the EBCM.
3 - Remove the wire harness by first removing the white plastic clip that locks it in place, then lift gray handle and pull back on the wire harness. At this point, you will be able to see the second wire connection that is removed by pulling down.
4 - The service manual calls for you the remove the 2 insulator nuts that hold the BPMV to the brackets and lift the EBCM/BPMV out of the bracket. I do not think this step is necessary because there is plenty of room while it is still in the bracket and you do not gain much additional clearance since the brake lines restrict the movement.
5 - Remove the 6 T-20 torx screws connecting the EBCM and BPMV - 1 on each corner and 2 on the sides.

6 - "Separate the EBCM from the BPMV by gently pulling apart until separated" - I should start laughing here, but it's not that funny. It's been my experience that anytime the instructions call for you to do something gently, nothing gentle is going to work. In this case, you might need that flathead screw driver to brake the seal. Once it moves a little, the rest is easy.

Once you receive your module back from us, follow the above instructions in reverse or just follow the instructions below to install your repaired module.

7 - At this point, all you've got to do is put it all back together. push the new EBCM onto the BPMV.
8 - Replace the 6 T-20 torx screws
9 - reconnect the wire harness
10 - put the intake back on
