Tesla 1037123-00-B brake booster

Description

The 1037123-00-B was the second iBooster Tesla started using in their Model S. It’s not exactly clear what the differences between the -A and -B are. Perhaps some firmware improvements?

While adopting the vacuum-independent, electromechanical brake booster developed by Bosch Tesla was able to implement autonomous braking as part of their Autopilot functionality. This version of the iBooster is currently known as the GEN1 model.

This is a used iBooster in working condition removed from a left hand drive (LHD) model S. The master brake cylinder outlets are at the right hand side. The ECU can be swapped/rotated 180 degrees to the other side in case that is more convenient.

While using the iBooster GEN1 connector kit you can integrate the iBooster in your own wiring harness.

Details on that can be found in the ‘Wiring the Tesla iBooster‘ blogpost.
