Removal Procedure
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.
- 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 brake pipes (1) from the BPMV (2).
- Swing the four brakes pipes out of the way only after covering
the open pipes to avoid dripping or being contaminated.
- Disconnect the master
cylinder brake pipes (2) from the BPMV (4).
- It is not necessary to remove the brake pipes (2) from
the master cylinder (1).
- Swing the two master cylinder brake pipes out of the way only
after covering the open pipes to avoid dripping or being contaminated.
- Remove the two BPMV mounting
bracket nuts (3) and one bolt located near the bottom and one nut (1)
located at the top of the BPMV mounting bracket (4) to the strut
tower.
- Disconnect the ground strap between the EBCM assembly and the
chassis.
- Remove the BPMV mounting bracket (4) and EBCM assembly (2)
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 four bolts (3) that connect the BPMV (1) 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 (1) to the mounting
bracket (2).
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 four bolts (3) that
connects the BPMV assembly (1) to the mounting bracket (2).
Tighten
Tighten the four bolts (3) that connect the BPMV (1) to
the mounting bracket (2) to 10 N·m (89 lb in).
- Install the BPMV bracket (4)
to the strut tower.
- Install the one bolt and three nuts that attach the BPMV mounting
bracket (4) to the strut tower.
Tighten
• | Tighten the lower two BPMV mounting bracket nuts (3) and
bolt to 10 N·m (84 lb in). |
• | Tighten the top nut (1) for BPMV mounting bracket (4)
to strut tower to 3 N·m (27 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 during the next few steps when ready .
- Install the master cylinder brake pipes (2) into the BPMV (4).
Tighten
Tighten the master cylinder brake pipe fittings to 24 N·m
(18 lb ft).
- Install the brake pipes (1)
on the BPMV (2).
Tighten
Tighten all four brake pipe fittings to 24 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 cruise control module.
- When all procedures have been completed, the automated ABS bleed
procedure is required. Refer to
Antilock Brake System Automated Bleed Procedure
.
