Removal Procedure
Caution: For safety reasons, the brake pressure modulator valve assembly must
not be repaired, the complete unit must be replaced. With the exception of
the EBCM, no screws on the brake pressure modulator valve assembly
may be loosened. If screws are loosened, it will not be possible to get the
brake circuits leak-tight and personal injury may result.
- Remove the battery. Refer
to
Battery Replacement
in Engine Electrical.
- Remove the battery tray.
Important: Note the locations of the brake pipes in order to aid in installation.
- Disconnect the caliper and wheel cylinder brake pipes (2) from
the BPMV (3). Cover the ends of the brake pipes to avoid dripping or
contamination.
- Disconnect the master cylinder brake pipes (1) from the
BPMV (3). Cover the ends of the brake pipes to avoid dripping or contamination.
- Raise and support the vehicle on a suitable hoist. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the front engine splash shield.
- Remove the left engine splash shield.
- Disconnect the Connector
Position Assurance (CPA) (2) from the EBCM connector.
- Push the lock tab (1) down and then move the sliding connector
cover to the open position.
- Disconnect the EBCM harness
connector (2) from the EBCM (1).
- Remove the BPMV retaining
nut (2).
- Remove the EBCM/BPMV assembly (3) from the vehicle.
- Remove the two bolts (1)
attaching the BPMV bracket (2) to the frame.
- Remove the BPMV bracket (2) from the vehicle.
Installation Procedure
- Install the BPMV bracket (2)
to the vehicle.
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 two
bolts (1) attaching the BPMV bracket (2) to the frame.
Tighten
Tighten the bolts to 25 N·m (18 lb ft).
- Install the EBCM/BPMV
assembly (3) to the vehicle.
- Install the BPMV retaining nut (2).
Tighten
Tighten the retaining nut to 10 N·m (7 lb ft).
- Connect the EBCM harness
connector (2) to the EBCM (1).
- Push down the lock tab (1)
and then move the sliding connector cover back in the home position to lock.
- Insert the CPA (2) back into place.
- Install the left engine splash shield.
- Install the front engine splash shield.
- Lower the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
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.
- Connect the master cylinder brake pipes (1) to the BPMV (3).
Tighten
Tighten the brake pipe fittings to 24 N·m (18 lb ft).
- Connect the caliper and wheel cylinder brake pipes (2)
to the BPMV (3).
Tighten
Tighten the brake pipe fittings to 24 N·m (18 lb ft).
- Install the battery tray.
- Install the battery. Refer to
Battery Replacement
in Engine Electrical.
- Perform the
Antilock Brake System Automated Bleed Procedure
.
- Perform the
Diagnostic System Check - ABS
.
