Suck out what u can from the master reservoir. The best, simple way to bleed brakes for a brake fluid change is gravity bleed: If you have traction control leave the key turned on. I'd love to get one for myself, but my buddy says it's an $8000 scan tool! Looks like I'll just stick with my $600 OTC scan tool instead.I can't see your vehicle details? Does it have traction control? I assume not. It can do just about anything and it's very user friendly. Now, the booster pump only comes on after I hit the brake pedal four times.īTW, the Snap-On Modis scan tool is awesome. I tried this several times and it always took two applications of the brake pedal before the booster pump would come on. In other words, with the engine running and sitting stationary, if I hit the brake pedal once, the booster pump wouldn't come on, but on the second time I hit the brake pedal, the booster pump would come on. Yesterday, I noticed that the booster pump would come on every two applications of the brake pedal. The pedal feels a lot better now and I also noticed that the booster pump doesn't run nearly as much as it was before we bled it using the scan tool. So I'm not really sure how or why, but I do think it had to have something to do with air in the master cylinder solenoid.

When we finished, I took the 4Runner for a ride and the cruise control was now working. Then we bled all four wheels conventionally, with me inside pumping the brake pedal (for the fronts) and holding the brake pedal down for the rears. We repeated that for 6 or 7 times on the right side and then did the same thing on the left side. It ran for about 2 or 3 seconds and then shut off automatically. We loosened the bleeder on the right side rear first and then used the scan tool to drive the solenoids.
#TECHSTREAM BRAKE BLEEDING MANUAL#
Then we used the scan tool to bleed the master cylinder solenoids using the "SRMF & SRMR" settings, as per the factory service manual procedure. So I went to my buddy's shop this morning and we used his Snap-On Modis scan tool to first check for codes. (the program using the TIS only runs them for something like 4-6 seconds) One concern with it that Toyota made clear in their documentation was to not run the solenoids too long as you may burn them out. I'm not sure if the Snap-On tool does the same thing or just does a straight on/off hold on the solenoids, we used to use a sort of manual ABS tool that plugged into the harness and just turned solenoids on and off. My only concern is that the TIS Techstream runs a preprogrammed routine when bleeding the brakes. I would print out the service procedure just in case.
#TECHSTREAM BRAKE BLEEDING SOFTWARE#
Uhmm, not sure about the Chinese stuff, but Toyota has has the TIS TechStream Light software out for a year or so now? You just buy a Monster Cable OBDII adapter I believe, I don't have any experience with it myself, I just know Toyota released it this year IIRC.Īs for the Snap-On tool, I haven't used one to bleed the system with, but I don't see why it couldn't. I'm taking a ride down there tomorrow morning to bleed everything and see what happens.

My friend (who owns a shop) has a Snap-On scan tool that can bleed the ABS module. Are you talking about the pirated Chinese TIS cables/software? If not, where can I get the original for a decent price?
