Removal Procedure
Caution: To help avoid personal injury, due to a retained load on the brake modulator,
the Gear Tension Relief function of the scan tool must be performed prior
to removal of the ABS brake modulator/master cylinder assembly.
- Use the scan tool in order
to perform the Gear Tension Relief Sequence.
- Disconnect the 2 brake solenoid valve electrical connectors (1,3).
- Disconnect the brake fluid level indicator sensor connector (2).
- Disconnect the ABS brake motor pack 6-way electrical connector (6).
- Remove the 4 brake pipes (5).

Installation Procedure
- Install the ABS brake
modulator/master cylinder assembly (7) into 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 2 nuts (8)
in order to attach the ABS modulator/master cylinder assembly (7).
Tighten
Tighten the ABS brake modulator/master cylinder nuts (8) to 27 N·m
(20 lb ft).
- Install the 4 brake pipes (5) onto the ABS brake
modulator/master cylinder assembly (7).
Tighten
Tighten the tube nuts to 24 N·m (18 lb ft).
- Connect the ABS brake motor pack 6-way electrical connector (6).
- Connect the brake fluid level indicator sensor electrical connector (2).
- Connect the 2 brake solenoid valve electrical connectors (1,3).
- Bleed the system. Refer to
