The steering input device is mounted to the steering arm behind the steering
wheel. The steering input device includes a hall effect sensor that reports the
steering wheel position to the SC7: Steering Motor. The steering input device
sensors operate on 5 VDC supplied by the steering motor. The steering input
device is not directly connected to the CAN bus.
The steering input device also includes a brake coil which creates drag
(feedback) for a more “natural” feel when turning the steering wheel. The brake
coil is controlled by a pulse width modulated (PWM) signal from the T1: Primary
controller.
The steering input device is not serviceable, and is best tested by using the
information provided on the InfoCenter display as described in the following test
procedure. Refer to
Appendix A (page A–1)
for circuit wiring information.
Note:
If the steering input device is removed or replaced for any reason, the
steering system – center must be calibrated; refer to
System – Center (page 5–91)
.
