Control Module
WARNING: This page is about a different car, the 2005 Suzuki Reno and 2005 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
The SSPS control module processes the vehicle speed information from the engine control module (ECM) and uses the steering wheel rotation sensor to provide a control signal to the electronic variable orifice (EVO) actuator located on the power steering pump.
