Abs Bleeding Procedure
NOTE:
Bleeding ABS system requires the use of Tech 2 scan tool. An assistant is required when performing bleeding procedures.
- Raise and support vehicle. Begin bleeding at right rear wheel. Install a clear plastic hose to bleed screw. Immerse other end of hose in container that is partially filled with clean brake fluid.
- Open bleed screw 1/2 to 1 full turn. Have assistant slowly depress brake pedal until it reaches full travel. Hold pedal until bleed screw is closed. Release brake pedal and wait 10-15 seconds. Repeat until clean bubble-free brake fluid is present at wheel bleed screw.
- Check master cylinder fluid level every 4-6 strokes of brake pedal to avoid running system dry. Repeat procedure on left rear, then right front, then left front. After bleeding all 4 wheels, go to next step.
- Using scan tool in FUNCTION TEST, run FUNCTION TEST 4 times consecutively while applying the brake pedal firmly. Release brake pedal between each test.
- Rebleed all 4 wheels to remove remaining air from brake system. Ensure brake pedal feel is appropriate before attempting to drive vehicle. Rebleed as many times as necessary to obtain appropriate pedal feel.
