Electronic Brake Control Module (EBCM) Replacement

Removal Procedure

Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in Service Precautions.

1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.





Important: Plug open brake pipes to prevent brake fluid loss and contamination.

2. Disconnect the brake pipe nuts from the Brake Pressure Modulator Valve (BPMV).





Important: After removing brake pipe nuts, do not excessively pull or bend brake pipes away from master cylinder.

Important: Plug open brake pipes to prevent brake fluid loss and contamination.

3. Disconnect the brake pipe nuts from the master cylinder.
4. Slide out the locking tab and disconnect the Electronic Brake And Traction Control Module (EBCM) electrical connector.

Important: Do not bend brake pipes.

5. Remove the ABS control module mounting nuts and the bracket.
6. Remove the ABS control module from the vehicle.

Assembly Procedure

Important: Do not attempt to repair a damaged solenoid pack or control unit assemblies. Repair of these assemblies is not possible. Do not lubricate or oil the EBCM.

1. Disconnect the pump motor electrical connector.
2. Remove the EBCM to BPMV screws.
3. Separate the EBCM from the BPMV.
4. Position the EBCM on the BPMV.
5. Install the attaching screws.
6. Connect the pump motor electrical connector.

Installation Procedure





Notice: Refer to Fastener Notice in Service Precautions.

1. Position the ABS control assembly into the bracket and tighten the nuts.
Tighten the ABS control assembly-to-bracket nuts to 20 Nm (15 ft. lbs.).





2. Position the brake pipes into the master cylinder and tighten the brake pipe nuts.
Tighten the brake pipes-to-master cylinder to 18 Nm (13 ft. lbs.).





3. Position the brake pipes into the ABS control assembly and tighten the brake pipe nuts.
Tighten the brake pipes-to-master cylinder to 18 Nm (13 ft. lbs.).





Important: Ensure that all the electrical connections are fully seated and the latches are engaged.

Important: If the EBCM was replaced, make sure to program the correct engine and transaxle options in the EBCM. Refer to option bit configuration with scan tools.

4. Install the electrical connector to the ABS control assembly.
5. Install the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure in Engine Electrical.
6. Fill the brake fluid reservoir with clean brake fluid up to the "MAX" mark on the reservoir.

Important: It is not required or recommended to bleed the ABS controller. Automated bleeding of the ABS controller may induce air into the system.

7. Bleed the brakes. Refer to Hydraulic Brake System Bleeding (Manual) or Hydraulic Brake System Bleeding (Pressure) in Hydraulic Brakes.
