Memorizing the Torque Sensor Neutral Position
A
The torque sensor neutral position must be memorized
whenever the steering gearbox, the torque sensor, the
EPS 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 temperature sensitive.
When memorizing the torque sensor neutral position,

1. With the ignition switch in LOCK (0), connect the HDS to the data link connector (DLC) (A) located
under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the EPS control unit. If it doesn’t, troubleshoot
the DLC circuit (see page 11-204).
4. From the EPS MENU, select MISCELLANEOUS TEST, then TORQUE SENSOR LEARN, and follow
the screen prompts on the HDS.

All four tire pressure sensor IDs must be memorized to
the TPMS control unit whenever you do any of these
actions: Replace the TPMS control unit.
 Replace the tire pressure sensor.
 Substitute a known-good wheel with tire pressure sensor.
NOTE:  To ensure the control unit memorizes the correct ID, the vehicle with the new sensor must be at least 3 m
(10 ft) away from other vehicles that have tire
pressure sensors.
 When doing a tire rotation, memorizing the sensors in not needed.
1. With the ignition switch in LOCK (0), connect the HDS to the data link connector (DLC) (A) located
under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the TPMS control unit. If it doesn’t,
troubleshoot the DLC circuit (see page 11- 204).
4. Select Sensor ID Learning from the mode menu on the HDS. 5. Turn on the TPMS tool by pressing the green select
button. Press the green select button until the
proper light sequence is illuminated as per the tool
user’s manual.
6. Hold the TPMS tool near one wheel, memorize the tire pressure sensor ID by following the screen
prompts on the HDS.
NOTE: If you turn the ignition switch to LOCK (0) before memorizing all four sensor IDs, the memorizing
ID is canceled.
 See the HDS Help menu for specific instructions.
7. Repeat step 6 for each wheel until all four sensor IDs are memorized. When all four IDs are
memorized, the low tire pressure indicator blinks.
