Just a quick question to all those that have had experience with the Bosch ABS system, since it could save me some time and $$$; when I turn the key to the on position, I hear the relay one of the relays click about 3 times and the ABS light flashes in unison as well, then the light goes out; it will stay out until I begin to drive, and then it will stay on; I am familiar with the fact that the system is supposed perform a self-test at about 4 miles per hour, which unfortunately, the system is not doing now; before I pick up one of the Kent-Moore J35890 ABS testers on line, which I can get pretty cheap, are there any other easy checks to perform? I have the FSM, however it doesn't say you can do much other than check the "BRAKE" and "GAUGE" fuses, and make sure all the wheel speed sensors are seated properly; any suggestions to those who have gone through some testing? I'm guessing it's probably not the relays, since I can hear one clicking; hopefully it's just one of the wheel sensors, but will need the tool so I don't just start replacing unnecessary parts; actually, now that I'm mentioning it, does anyone have the AC Delco parts #'s for both the pump motor and solenoid relays that sit on top of the modulator valve? If they are fairly cheap, I may start with those 2, since even though I can hear one of them clicking, not sure if the other is working as well.......
