REMOVAL & INSTALLATION
See Figure 1
The solenoid control valves are located on top of the ABS control assembly, which is mounted to the power brake booster. The valves are directly outboard of the master cylinder. There are 2 different valve types which can be identified by an 8-digit number etched on top of the valve and referenced in the Saturn parts catalog. Always be sure to use the correct replacement type.
- Disconnect the negative battery cable, then clean the dirt from the area surrounding the solenoid valve.
- Unplug the electrical connector from the valve.
- Remove the 2 Torx® head retainers, then remove the solenoid.
- Check to see if the O-ring remained in the valve groove and was lifted up from the modulator bore, as should occur if equipped with the type A solenoids. If using a type B solenoid, or if the type A O-ring remained in the bore, carefully extract the valve lip seal or O-ring from the modulator.
- Lubricate the valve O-ring or lip seal with clean brake fluid and install onto the valve. O-rings should be installed into the groove provided on the solenoid. Lip seals should be inserted over the bottom of the valve with the lip or cupped side of the seal facing upward toward the solenoid top.
- Position the solenoid into the modulator and push downward until the valve flange is fully seated. Install the 2 screws and tighten to 45 inch lbs. (5 Nm).
- Install the wiring harness electrical connector to the valve, then connect the negative battery cable.
- Properly bleed the anti-lock brake system. Refer to the procedure later in this section.
See Figure 2
- Disconnect the negative battery cable.
- Disengage the solenoid valve electrical connector.
- Using an ohmmeter, measure the resistance between circuits A and B of the solenoid valve connector terminal.
- If the resistance measures below 200 ohms, check for continuity of the power circuit. If the power circuit displays continuity, replace the solenoid valve.
- If necessary, repeat these steps on the other solenoid valve.
