Notice: To prevent equipment damage, never connect or disconnect the wiring harness connection from the EBCM with the ignition switch in the ON position.

Notice: Avoid getting water, brake fluid or engine coolant into the socket of the EBCM/EBTCM connector. Failure to observe this precaution could result in damage to the EBCM/EBTCM.

1. Turn the ignition switch to the OFF position.
2. Remove the cover from the relay center (1).
3. Remove the Engine Control Module (ECM) (2) from the relay center (1). Move the ECM harness to one side.
4. Remove the lower radiator hose from the engine only. Refer to Radiator Outlet Hose Replacement in Engine Cooling. Move the radiator hose to one side.



5. Pull out lock tab from the EBTCM harness connector (1).
6. Disconnect the EBTCM harness connector .



7. Disconnect the pump motor connector (3) at the bottom of the EBTCM.
8. Remove the six EBTCM to BPMV screws (2) and discard.
9. Separate the EBTCM (1) from the BPMV (5) by gently pulling apart until separated.

Important: Be careful not to damage seal. Do not pry apart using a tool.

Important: Care must be taken not to damage the solenoid valves when the EBTCM is removed from the BPMV.




10. Remove two wave springs (1) between the EBTCM and BPMV and discard.

Important: Note the location and the orientation of the wave springs in order to aid during installation.

Important: Only the new wave spring(s) and screws supplied with the new EBTCM should be used.

1. Clean the BPMV gasket surface with alcohol using a clean rag.



2. Install two wave springs (1) between the EBTCM and BPMV. Use locations and orientation noted during removal.



3. Install the EBTCM (1) to the BPMV (5).

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.

Tighten
Tighten the bottom two mounting screws (2) to 2.9 N·m (26 lb. in.).

4. Connect the pump motor connector (3) to the bottom of the EBTCM.



5. Connect the EBTCM harness connector. Push in lock tab (1).



6. Install the lower radiator hose to the engine. Refer to Radiator Outlet Hose Replacement in Engine Cooling.
7. Install the ECM (2) into the relay center (1).
8. Install the cover to the relay center (1).
9. Turn the ignition switch to the RUN position, engine off.
10. Perform the Diagnostic System Check - ABS
