Hmm. From the Honda Talon service manual, and described
here.
STEERING ANGLE SENSOR INITIALIZATION (Except after '22)
NOTE:
• Perform this procedure using a fully charged battery. The FLV warning indicator will stay lit and the SCU will abort the process if
you use a low or dead battery.
• The OTC will be erased when initializing the steering angle sensor.
How to Initialize the Steering Angle Sensor with MCS
1. Position the front wheel at oriented straight forward.
2. Connect the MCS to the DLC (page 4-10).
3. Turn the ignition switch ON (I) and display the steering angle sensor initialization window.
NOTE:
• Do not touch the steering wheel and tires until the initialization is completed.
4. Initialize the steering angle sensor in accordance with the MCS instructions.
How to Initialize the Steering Angle Sensor without MCS
1. Position the front wheel at oriented straight forward.
2. Short the DLC using the special tool (page 4-10).
3. Press and hold the normal mode button (FLV switch) [1].
4. Turn the ignition switch ON (I).
The FL V warning indicator [2] comes on and goes off during combination
meter initialization.
Continue to hold the normal mode button (FLV switch) until the FLV
warning indicator comes on and goes off again.
5. After the FLV warning indicator [1] goes off, release the normal mode
button (FLV switch) [2].
The FL V warning indicator comes on again after 4 seconds.

6. After the FLV warning indicator [1] comes on, press the normal mode
button (FL V switch) [2] and hold it.
The FL V warning indicator goes off after 4 seconds.
7. After the FLV warning indicator [1] goes off, release the normal mode
button (FLV switch) [2].
The FLV warning indicator blinks twice. (The OTC is erased at this time.)

8. Within 5 seconds after the FLV warning indicator blinks twice, press the normal mode button (FLV switch) and hold it.
NOTE:
• Do not touch the steering wheel and tires until the initialization is completed.
9. Turn the ignition switch OFF (0) after the FLV warning indicator blinks one more time (steering angle sensor initialization is
completed at this time).
NOTE:
• If the FLV warning indicator does not blink as in step 10, an error was made in the procedure and the steering angle sensor was
not initialized. Turn the ignition switch OFF (0), and repeat the operation from step 3.
10. Remove the special tool from the DLC and connect the DLC to the dummy connector
