Steering: Specifications Honda Fit I

Torque Sensor Neutral Position

The EPS control unit stores the torque sensor neutral position in the EEPROM. The torque sensor neutral position must be memorized whenever the gearbox, the motor, or the EPS control unit is replaced.

Note. The torque sensor neutral position is not affected when erasing the DTCs.

Memorizing the Torque Sensor Neutral Position

The torque sensor neutral position must be memorized whenever the gearbox, the motor, or the EPS control unit is replaced, and after doing a wheel alignment. Note that the torque sensor neutral position is not affected when erasing the DTC.

Note. The torque sensor is sensitive to temperature. This procedure should be performed within the range of 68 ± 18°F (20 ± 10°C).

Scheme 1

1. With the ignition switch OFF, connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
