Removal Procedure
Refer to Brake Fluid Irritant Warning .
Refer to Brake Fluid Effects on Paint and Electrical Components Caution .
Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM.
- Place the transmission in PARK.
- Place the power button in the OFF position.
- Remove the remote keyless entry (RKE) transmitter and close all of the vehicle doors.
- Wait approximately 3 minutes for the HPA pressure relief to occur.
- Remove the front suspension strut housing brace. Refer to Front Suspension Strut Housing Brace Replacement .
- Disconnect the electronic brake control module (EBCM) electrical connector.
- Remove the brake pressure modulator valve (BPMV) bracket bolt (1).
- Without disconnecting the connectors, remove the fasteners and position the drive motor generator power inverter module aside. Refer to Drive Motor Generator Power Inverter Module Replacement .
- Remove the bolt and position aside the engine wiring junction block.
- Disconnect the BPMV return hose quick connect (1).
- Cap the BPMV outlet port and plug the return hose to prevent brake fluid loss and contamination.
- Disconnect the BPMV supply hose quick connect (1).
- Cap the BPMV inlet port and plug the supply hose to prevent brake fluid loss and contamination.
- Disconnect the right rear (1) and left rear (2) brake pipe fittings from the BPMV.
- Cap the brake pipe fittings and the BPMV outlet ports to prevent brake fluid loss and contamination.
- Disconnect the left front (1) and right front (2) secondary brake pipe fittings from the BPMV.
- Cap the brake pipe fittings and the BPMV outlet ports to prevent brake fluid loss and contamination.
- Disconnect the master cylinder primary brake pipe fitting (1).
- Cap the brake pipe fitting and the BPMV inlet port to prevent brake fluid loss and contamination.
- Remove the BPMV bracket nut (1).
- Remove the BPMV bracket bolt (1).
- Remove the brake master cylinder. Refer to Master Cylinder Replacement .
- Carefully move the front brake pipes and remove the hydraulic control unit and bracket assembly.
- Remove the EBCM bolts (1).
- Carefully separate the EBCM (1) and seal (2) from the BPMV. Do not pry or force the components apart.
The transmission must be in the PARK position, the power button in the OFF position, and the brakes not applied to ensure the brake modulator and high pressure accumulator (HPA) pressure relief occurs. This process will take approximately 1 to 3 minutes.
Mark the location of the brake pipe fittings at the BPMV to ensure correct installation.
Mark the location of the brake pipe fittings at the BPMV to ensure correct installation.
Do not pry the EBCM from the BPMV. The EBCM must be pulled back evenly.
