    I just replaced the brake pump and actuator on my 2013 toyota prius and i'm having trouble connecting to the unit with scanner tool which is MaxiSys MS906TS. When i try to preform the brake bleeding procedure i get a message that says "Device unable to communicate with the control unit." any help would be greatly appreciated. maybe a different scanner tool or any other suggestions would be a lot of help.

    thanks

    Sometimes this happens You got to make sure if you haven't looked at the factory manual dialogue there's all kinds of things the parking brake has to be down and so on and so forth I don't know whether the aultel system gives you those primers at the beginning of each step or the start of the system whatever so you may need to check that usually when you get that message you haven't done something that needs to be done before you start the whole business.

    yeah i think so, i've ordered a new usb cable to make sure its not that. i will check again tomorrow when i get it. the battery 14.76v. i attached a NOCO Boost Plus 12.V 1000A to the battery to make sure the car battery doesn't die. here is a photo of what pops up when it won't connect.

    Did you buy a new OEM brake pump and actuator or used parts?
