Overview, ABS 2E


ABS 2E on Saab 900 M94-95 cars consists of three main components:



• Wheel sensors

• Hydraulic unit (incl. valve block)

• Control module with relays


The ABS on the Saab 900 M94-95 is a 2-circuit, 3-port braking system.

Four wheel sensors at the wheels send signals to a control module. This calculates wheel acceleration, (speed increase), wheel retardation (speed decrease), car speed and slip (locking degree) based on continual signals. If any of the wheels approaches its locking limit, the control module sends signals to the solenoid valves in the valve block for the wheel concerned. The pressure in the wheel's brake circuit is modulated so that the maximum possible braking force is continually transferred to the road surface and the necessary steering capacity is maintained.
