7. St Wheel Feel is the amount of current being sent by the T1: Primary
controller to the steering input device brake coil, and not necessarily what is
being received by the coil. The steering input device brake coil amperage
characteristics are:
• St Wheel Feel should be approximately 220 mA when the steering wheel
is at rest or turned slowly in either direction.
• St Wheel Feel should be approximately 600 mA when the steering wheel
reaches the end of its turning range in either direction.
• St Wheel Feel should vary between 220 and 480 mA when the steering
wheel is turned quickly in either direction.
8. Remove the cover from the steering mount.
9. Disconnect the steering input device from the machine wire harness. Check
both connectors for corrosion or damage and clean or repair as necessary.
10. Use a multimeter (ohms setting) to measure the resistance of the brake coil
across the steering input device connector pins 5 and 6. Resistance should
be approximately 10 ohms at 20° C (68° F).
11. If the InfoCenter diagnostics inputs and outputs report normally, the brake coil
resistance measures correctly, and the steering input devise does not function
properly, replace the device; refer to
12. If the steering input device tests correctly and a circuit problem still exists,
check the machine wire harness; refer to
13. After testing, connect the machine wire harness, install the cover and
calibrate the steering system – center: refer to
