ABS module bleed suggestions????

the problem is the scanner won't link so I can't run the test function to clear the air out of the ABS module. I'll look for another plug on the module.I've tried holding the brake pedal down and running the function too, but it keeps saying it won't link to the module. I suspect it is the year of the chassis. 98 chevy

I have used the scanner tool to bleed the abs pump, not sure exactly what it does within the pump. but it does work, then you re bleed the system again after and you should get a hard pedal.
This is out of Mitchels on demand

1) raise and support Vechicle. Begin at the right rear wheel. Install clear plastic hose to bleed screw. immerse other end of hose in contaimer that is partially filled with clean brake fluid

2) Open bleed screw 1/2 to 1 full turn. Have assistant slowly depress brake pedal untill reaches full travel. Hold pedal untill bleed screw is closed. Release brake pedal and wait 10 -15 sec. repeat untill clean bubble free brake fluid is present at wheel bleed screw.

3) Check master cylinder every 4-6 strokes of brake pedal to avoid running dry. repeat procedure on left rear, then right front, then left front. after bleeding all 4 wheel go to the next step

4) Using scan tool in function test, run function test 4 times consecutivels while appling the brake pedal firmly. release brake pedal between each test.

5) Rebleed all 4 wheels to remove remaining air from brake system. ensure brake pedal feel is appropriat befor attempting to drive vehicle. Re bleed as nessary to obtain appropriate pedal feel.
