I'm getting the 17887 Brake Booster Failure code. I have take out the relay and tested it. It was fine.
But I can't find the protective fuse. Where is this? :confused:


Also should I really take apart the Brake Booster itself to see what's wrong inside?

Thanks

17887/ P1479/005241 - Brake Boost Vacuum System: Mechanical Failure. 17887/P1479/005241 - Ross-Tech Wiki

This is not referring to the Brake Booster there is nothing electrical in that, it is the Brake Boost Vacuum Pump.
I doubt you achieve anything by pulling that apart, if you have 12V to the pump and it's not running, I suggest you replace it.
If it is not getting 12V test to find out why, I don't know specifically where the fuse is.

Maybe you just have a vac leak or faulty check valve.

I pulled my pump apart theres nothing really in there to break. I checked the lines coming from the pump and there is a big hole in one of my lines. I throwing the same code as you.
huh... a hole in the line? I got to check mine again. If there's a hole that my explain the vac leak.
