I've got a '99 C1500 Suburban that has a bit of a swishy pedal.
When I performed the ABS bleed 4WAL procedure with a scan tool it only runs the ABS motor 2x times (pedal goes up and down and ABS pump actuates). All youtube videos I'm seen for this procedure runs the pump ~6x.
The scanner acts like it still is performing the procedure for another ~25 seconds after the first 2x pumps, but the module is silent and does nothing mechanical (I'm just holding the brake pedal). The dash ABS light may have blinked a few times during the procedure. The scanner then says it has completed the bleed procedure. I did this test procedure 3x and it acts the same each time like the module thinks all is working during the bleed test.
I have no ABS light on or indications that the module is bad. Any tips to diagnosis this sucker?
BTW: I used a Launch scanner, but I have a Tech 2 clone in the mail already.
