After replacing the Brake actuator

Here is a link to my original posting. I am making a new thread in hopes I can get more people to help.

NOw I get the code C1203 I tried a week attempt at bleeding air from the brakes manually (copied a youtube video) I got this error now as well as a C1247 Stroke sensor.

Now I have no pressure in Brake pedal and it won't allow me to do any of the brake bleeding, linear offset etc in Techstream just says Failed.

I have checked all the electrical connections and everything looks good.

I didn't however spray contact cleaner on all the connections to make sure brake fluid was clear of them.

Does anyone have any ideas?

Thanks in advance for your help.

 

Make sure that your skid control module is connected.

 

This is the black box that sits next to the Brake Fluid Reservoir?

 

Yes.

 

Sunday is Sabath wasn't going to mess with it anymore, while putting stuff away wife got out shopping in garage thought let me look at it....as I looked under something was dangling, middle plug wasn't plugged in and smiled to my idiot self and said "are you ***** f'n kidding me"

Will plug it in and reset tomorrow and update for future idiots to fix.

Thanks

 

Unplugged battery for 30 mins hooked it up ran techstream to clear codes and was able to run linear offset

ALL CODES ARE GONE no dash lights except SRS airbag system light now I have no pressure in the brake pedal. My actuator doesn't make that winding or coiling sound either.

I read somewhere to pump brakes with car off 20 times then start car got a little bit of pressure but after a couple seconds pressure goes away again.

is it because I didn’t blead the lines enough to get all the air out?

How do I get pressure in brake system?

Thanks for your help

 

Your brake system needs to be bled with techstream after you've replaced those parts.

 

Thanks I assume this is the whole process of bleeding at each wheel using techstream?

 

Alright, bled brakes with techstream and cleared all the codes...we are good to go.

Thanks for all your help!!
