Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

Caution: For safety reasons, the Brake Pressure Modulator Valve (BPMV) must not be repaired; the complete unit must be replaced. With the exception of the EBCM/EBTCM, no screws may be loosened. If screws are loosened, it will not be possible to get the brake circuits leak-tight and personal injury may result.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

3. Install the 2 BPMV nuts (1).

Tighten
Tighten the nuts to 12 N·m (106 lb in).





Caution: Make sure brake pipes are correctly connected to brake pressure modulator valve. If brake pipes are switched by mistake, wheel lockup will occur and personal injury may result. The only two ways this condition can be detected are by using a Scan Tool or by doing an Antilock stop.

Important: If a new BPMV is being installed, remove the shipping plugs from the valve openings in the compartment during the next step.

Important: Use the locations noted during removal.

4. Install the master cylinder inlet brake pipe fittings (1) to the BPMV (2).

Tighten
Tighten the fittings to 19 N·m (14 lb ft).




5. Install the BPMV outlet brake pipe fittings (1) to the BPMV (2).

Tighten
Tighten the fittings to 15 N·m (11 lb ft).




6. Connect the EBCM harness connector.
7. Engage the EBCM harness connector lock tab (1).
8. Bleed the antilock brake system. Refer to Antilock Brake System Automated Bleed Procedure .
