Brake Fluid Solenoid Valve Relay: Service and Repair

REMOVAL PROCEDURE





1. Disconnect the brake solenoid valve electrical connector (1).





2. Remove the Torx(R) head bolts (1).
3. Remove the solenoid (2) from the hydraulic modulator (4).

IMPORTANT:
^ Verify that the brake solenoid valve lip seal (3) is still attached to the brake solenoid valve (2) when removing the brake solenoid valve. If the seal is not attached, inspect the brake solenoid valve bore in the brake modulator.
^ Do not attempt to disassemble the brake solenoid valve. The brake solenoid valve is serviceable only as an assembly.

INSTALLATION PROCEDURE





1. Use the following procedure in order to install the brake solenoid valve lip seal (3):
1.1. Lubricate the seal on the new brake solenoid valve (2) with clean brake fluid.
1.2. Verify the brake solenoid valve lip seal (3) is properly positioned before installing the brake solenoid valve (2) in the ABS brake modulator (4).

2. Position the brake solenoid valve (2) so the brake solenoid valve electrical connector will face the same direction as the brake solenoid valve that was removed.
3. By hand, press down firmly on the brake solenoid valve (2) until the brake solenoid valve flange seats on the ABS brake modulator (4).

NOTICE: Refer to Fastener Notice in Service Precautions.

4. Install the Torx(R) head bolts (1).
^ Tighten the Torx(R) head bolts to 5 Nm (44 inch lbs.).

IMPORTANT: Verify proper installation of the brake solenoid valve connectors on the correct brake solenoid valve.





5. Reconnect the brake solenoid valve electrical connector (1).
6. Bleed the brake modulator/motor pack assembly.
7. Perform the ABS Diagnostic System Check
