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. 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 20°C ± 10°C (68°F ± 50°F)

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

Turn the ignition switch ON (II).
Make sure the HDS communicates with the vehicle and the EPS control unit. If it doesn't, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
From the EPS MENU, select MISCELLANEOUS TEST then TORQUE SENSOR LEARN and follow the screen prompts on the HDS.
NOTE: See the HDS Help menu for specific instructions.
Turn the ignition switch OFF.
