I am getting ready to do a brake flush on my 06 ram 2500 with ABS. The manual says :
"ABS BRAKE BLEEDING"
ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaning in the system."

I know how to do the "base" standard brake bleeding and flushing. But I don't have a DRB scan tool and don't even know what that is. I don't have any air trapped in my brake system now that I am aware of. I just want to replace the fluid! So do I really need to do this scan tool procedure? IF I don't do it will I still be flushing new fluid into the ABS pump and solenoids? Is this procedure only required to get the air out of the ABS components?

Any one have experience at this? Or is there an alternate way to get this flush done?

I bleed mine out every year doing the old fashion method at each wheel and it works fine. Use a Mighty Vac and pull fluid out until it is new.

If there is air in the system upstream of the ABS module, you'll need to follow the procedure you listed. Otherwise you'll never get the air out of the module.

If you're doing a standard flush during a brake job, just use the old fashioned compress and release method.

Mine is due later this year. When I did it 2 years ago, I used my pressure bleeder. Just be sure you have >2qts of fluid on hand.

I have always used a vacuum bleeder attached to one wheel at a time, and it works flawlessly. I generally will stick the hose into the reservoir first to vacuum out all the old fluid I can reach, then top it up with fresh before doing the wheels.

Thanks for the input guys,
I have a Motive Pressure bleeder. Sounds like as long as I don't have any air in the lines now above the ABS pump, and as long as I don't let the master cylinder get low, I should be OK.

Anybody else with ABS done a flush and bleed without the scan tool?? Or has anybody used the scan tool?

Do you think I will be getting all the old fluid out of the system if I don't use one?

You should be fine I did the 05 with a pressure bleeder and no scan tool as well. I upgraded to DOT 4 fluid to gain some temp on the boiling point.
