C1100 Saturn Description

The Electronic Brake Control Module (EBCM) provides a power 5-volt reference to the brake booster vacuum sensor. The brake booster vacuum sensor converts the change in vacuum levels in the brake booster into a voltage signal. This signal is sent to the EBCM. The voltage signal ranges, from 0.13 to 3.30 volts depending on vacuum levels. The low reference is the return side of the sensor to ground.
