5. The steering input device sensor signal voltage characteristics are:
• St Wheel Sig 1 and St Wheel Sig 2 voltages should decrease as you turn
the steering wheel to the right (clockwise).
• St Wheel Sig 1 and St Wheel Sig 2 voltages should increase as you turn
the steering wheel to the left (counterclockwise).
• The signal voltage range should be from 0.2V to 4.7V.
• When the signal voltage reaches either end of the voltage range, the
voltage will reset and continue to increase or decrease as you continue
to turn the steering wheel.
• The signal voltage should change from minimum to maximum in
approximately one complete revolution of the steering wheel.
• The difference between the 2 signal voltages should always be
approximately 2.5V.
