Re read what I sent in my first two replies as i'm not getting the info I need. Also do what I am sending to the anti lock unit, I think that is where your problem lies. Make sure you do this correctly then rebleed your whole system once more. I STRONGLY SUGGEST that you get a POWER bleeder to do this, autp partsstores may have them ifnot rental shops do. If this step fails then you will have to take it to a dealer to get codes from teh ABS unit and it will need to be fixed with a tech 1 and appropriate cartridge.
BRAKE PRESSURE MODULATOR VALVE
NOTE: It is not necessary to bleed BPMV during normal brake system bleeding. If BPMV is replaced or is suspected to have air in it, BPMV must be bled. Expect to use
2 3 quarts of fluid to thoroughly bleed system. Bleeding BPMV requires Tech 1 scan tool and appropriate cartridge.
1. Raise and support vehicle. Begin by bleeding the right rear wheel, then the left rear, right front and left front. Attach one end of clear tube over valve and submerge other end in container partially filled with clean
2. Loosen bleeder valve 1/2 1 turn. Have an assistant depress brake pedal slowly and hold. Tighten bleeder valve and slowly release brake pedal. Wait 10 15 seconds. Repeat sequence, including 15 second wait,
until one pint of fluid has been bled from wheel.
3. Remove tube and wrench. Repeat step 2) at left rear, right front, and left front wheels in this order. Clean brake fluid should be present at each wheel bleed screw. Check master cylinder fluid level every 4 6
strokes of brake pedal to avoid ingesting air into system.
4. If any component was replaced causing air to enter the BPMV, connect Tech 1 scan tool with RWAL/4WAL cartridge or Mass Storage Cartridge to Data Link Connector (DLC). Using Tech 1 scan tool,
perform 4 functional tests while firmly applying brake pedal.
5. Fill master cylinder reservoir, and install cover. Ensure there is no sponginess in brake pedal and that BRAKE warning light is off. Rebleed wheel cylinders/calipers to remove the remaining air in brake system.
Evaluate brake pedal feel and braking performance. Repeat bleeding procedure if necessary.
