Procedures

Bleeding System
Replacement modulators are shipped already filled and bled. In normal procedures requiring removal of the modulator, such as to replace the EBCM, air will not enter the modulator, and normal bleeding will be all that is needed.

If air enters the hydraulic modulator, or if an unfilled modulator is installed, use the brake bleeding program in the scan tool to bleed the modulator. Manual bleeding of the hydraulic modulator is not possible.

EBCM Assembly Removal and Installation

Removal
1. Disconnect the negative battery cable.
2. Disconnect the ABS wiring harness connector from its socket on the EBCM.
3. Cover the connector and the socket with shop cloths to protect them from brake fluid.





4. Remove the brake pipes from the hydraulic unit. It may be necessary to loosen the brake pipe nuts on the master cylinder to allow for moving those pipes out of the way.
5. Loosen the mounting nuts on the hydraulic unit.
6. Move the brake pipes aside far enough to allow for lifting the ABS unit out of the mounting bracket.
7. Tighten the brake pipe nuts on the master cylinder to avoid leaking brake fluid.
8. Cap the brake pipes.





Installation
1. Insert the EBCM assembly into its mounting bracket and install the nuts.
Tighten:
Tighten the EBCM assembly mounting nuts to 15 Nm (11 lb-ft).
2. Remove the screw plugs and install all of the hydraulic brake pipes.
Tighten:
Tighten the brake pipe nuts to 22 Nm (16 lb-ft).
3. Connect the wiring harness connector 1.
4. Connect the negative battery cable.
5. Bleed the hydraulic system.
