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 assembly.

1. Use the Scan Tool in order to perform the Gear Tension Relief Sequence.
2. Remove the Battery. Refer to Battery Replacement in Engine Electrical.
3. Remove the Battery tray.
4. Remove the radiator inlet hose. Refer to Radiator Hose Replacement in Engine Cooling.
5. Disconnect the two brake solenoid valve electrical connectors (2).
6. Disconnect the Brake Motor Pack electrical connector (1).



7. Disconnect the wheel cylinder to brake modulator brake pipes from the brake modulator.



8. Disconnect the master cylinder to proportioning valve brake pipes from the proportioning valve.



9. Remove the brake modulator assembly to bracket mounting nut.
10. Remove the brake modulator assembly.

1. Install the brake modulator assembly 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.
