Warning: Refer to Brake Fluid Irritant Warning in the Preface section.

Caution: Refer to Brake Fluid Effects on Paint and Electrical Components Caution in the Preface section.

Note: The ignition must be in the OFF position, without pausing at ACCESSORY, and without applying the brake pedal to ensure the brake modulator and high pressure accumulator (HPA) pressure relief occurs. This process will take approximately 1 to 3 minutes.

1. Turn the ignition to OFF, without pausing at ACCESSORY, and remove the ignition key.

Note: During the pressure relief process, the fluid level in the master cylinder reservoir will rise. Do not remove the master cylinder reservoir cap during the pressure relief process.

2. Wait approximately 1 to 3 minutes until the brake modulator and HPA pressure relief is complete.
3. Remove the brake fluid from the brake master cylinder reservoir until the level is below the reservoir supply hose fitting and discard into an approved container.
4. Disconnect the brake fluid level sensor electrical connector.



5. Disconnect the brake master cylinder reservoir return hose quick connect (1).
6. Disconnect the brake master cylinder reservoir supply hose quick connect (2).

12. Disconnect the BPMV supply hose quick connect (1).

Cap the BPMV inlet port and plug the supply hose to prevent brake fluid loss and contamination.




13. Disconnect the BPMV return hose quick connect (1).

Cap the BPMV outlet port and plug the return hose to prevent brake fluid loss and contamination.

14. Release the supply and return hoses from the retainers and remove the hoses from the vehicle.

1. Install the supply and return hoses to the vehicle and the retainers.
2. Connect the BPMV return hose quick connect (1).

Ensure the return hose quick connect is fully engaged by attempting to pull the return hose from the outlet fitting.




3. Connect the BPMV supply hose quick connect (1).

Ensure the supply hose quick connect is fully engaged by attempting to pull the supply hose from the inlet fitting.




4. Install the ABS module splash shield (1).

Caution: Refer to Fastener Caution in the Preface section.
