Removal Procedure
Caution: Refer to Brake Fluid Irritant Caution in the Preface section.
Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice 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.
- Turn
the ignition switch to the OFF position.
- Remove the attaching bolts for the cruise control module.
- Swing the cruise control module off to the side.
- Remove the air cleaner housing from the engine compartment. Refer to
Air Cleaner Assembly Replacement
in Engine Controls.
- Disengage the red locking tab from the connector (1).
- Push down lock tab (1) and then move sliding connector cover (2)
to the open position.
- Disconnect the EBCM harness connector.
Important: Note the locations of the brake pipes in order to aid in installation.
- Disconnect the 4 wheel brake pipes from the BPMV.
- Swing the four wheel brake pipes out of the way only after covering the
open pipes to avoid dripping or being contaminated.
- Disconnect the master cylinder brake pipes
from the BPMV.
- Loosen the brake pipes but do not remove the brake pipes from the master
cylinder.
- Swing the 2 master cylinder brake pipes out of the way only after covering
the open pipes to avoid dripping or being contaminated.
- Remove
the 3 BPMV mounting bracket nuts (2) from the inner wheel housing mount surface
of the strut tower.
- Reinstall the top nut upside down on the top stud.
- Lightly tap on the bottom of the nut until the stud has loosened up.
- Disconnect the ground strap between the EBCM assembly and the chassis.
- Remove the BPMV mounting bracket and EBCM assembly from the vehicle.
Notice: When removing the brake pressure modulator valve, protect the vehicle
exterior from possible brake fluid spillage. Brake fluid can cause damage
to painted surfaces.
- Remove the two bolts (1) that connect the BPMV to the mounting
bracket (2).
- Remove EBCM if replacing the BPMV only. Refer to
Electronic Brake Control Module Replacement
.
Installation Procedure
- Install EBCM onto the BPMV (1) if replacing the BPMV only. Refer to
Electronic Brake Control Module Replacement
.
- Install BPMV and EBCM as an assembly to the mounting bracket.
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.
- Install the 2 bolts (1) that connects the BPMV assembly to the mounting bracket (2).
Tighten
Tighten the 2 bolts 10 N·m (84 lb in).
- Install
the BPMV bracket to the strut tower.
- Install the 3 nuts (2) that attach the BPMV mounting bracket to the strut
tower.
Tighten
• | Tighten the nuts to 10 N·m (89 lb in). |
• | Reposition any lines or hoses that were moved out of place. |
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 during the next few steps when ready .
- Install the master cylinder brake pipes into the BPMV .
Tighten
Tighten the fittings to 24 N·m (18 lb ft).
- Install the four wheel brake pipes on
the BPMV .
Tighten
Tighten the fittings to 25 N·m (18 lb ft).
- Reconnect the ground strap between the EBCM assembly and the chassis.
- Connect
the EBCM harness connector.
- Push down lock tab (1) and then move sliding connector cover (2)
back in home position to lock.
- Insert red locking tab back in place.
- Reinstall the air cleaner housing. Refer to
Air Cleaner Assembly Replacement
in Engine Controls.
- Reinstall the cruise control module.
- When all procedures have been completed, the automated ABS bleed procedure
is required. Refer to
Antilock Brake System Automated Bleed Procedure
.
