Circuit Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Cadillac Escalade EXT. However, it is still accessible from the selected car via links, so may be relevant.

The Steering Wheel Position Sensor is a 0-5 volt device which is used to sense steering wheel position and turning speed. The valid output or signal voltage range from the sensor is 0.35-4.75 volts. The signal voltage will increase or decrease within the valid voltage range as the steering wheel is turned. The sensor has 2 output signals, signal 1 and signal 2. Both signals are used by the Suspension Control Module on vehicles equipped with Real Time Damping (RTD), to calculate lateral acceleration. When the control module detects lateral acceleration is occurring less current is commanded to the Electronic Variable Orifice (EVO) solenoid. This increases steering assist during abrupt driving maneuvers.

NOTE: The BCM/ESC stores the DTCs scan tool data and special functions. However, the scan tool menu to access variable effort steering is located in chassis.
