So I just swapped both rear calipers out on my truck for rebuilt units & replaced all three rear brake lines. I am going to bleed all four corners normally but i was curious about the ABS system. I just had the master cylinder done and had a full bleed completed (around 500 miles before doing the rear calipers). In the master cylinder replacement thread there was some comment that the ABS system needs to be bled via tech stream. Is this only required when replacing the master cylinder or do I need to do it when I do a normal brake job too?
ABS Bleed after caliper swap?

I did a full ABS bleed on the weekend as I was about due for a fluid change and all this brake talk motivated me. In your case if the fluid is fresh and recently bled due to your MC work I'd be comfortable just doing a "normal" ignition on four corner bleed.
If you follow the FSM verbatim it has you firstly do the conventional ignition on four corners then hook up techstream or the sst to activate the four corner ABS ccts for a final bleed.

Were you able to get Techstream to activate ABS solenoids?
Yes. You can use either the Toyota hand held tester aka techstream or the abs actuator checker sst as per BR-4 of 2004 FSM. Using techstream you select which line FR, FL etc depress brake, open bleeder, push next on techstream and it opens the solenoid for 4 secs. You have to wait 20 secs between activations.
Gotcha, so you weren't able to do it with the software Techstream on a laptop with the USB adapter cable? I couldn't get mine to do it.
Yes.
Where does one get the special USB cable?
