4.

If the GDS shows:
• The correct Current Gear, the wiring currently has no open/short circuits. Go to Step 6.
• Does not show the correct Current Gear, go to Step 5.

5.

Visually check the wiring harness between the ECU or TCU and position sensor for a damaged
wire or open circuit/short circuit to ground. Check for a damaged pin or pin not fully inserted
into the connector.
• If damage is found, repair or replace the control wiring and drive the vehicle to confirm the
repair.
• If no damage or open/short circuit is found, go to Step 6.

6.

Check the grounds for the electronic
shift lever. (Refer to ETM, SD450-1).
Turn the ignition and headlights on. Use
a DVOM to check the voltage drop
between the wiring terminal and
ground.
Specification: Less than 0.2 V.
• If more than 0.2V, clean the terminal
and bolt threads and tighten the bolt.
• If less than 0.2V, go to Step 7.
Torque: 7~9 lb-ft,1.0~1.2kgf.m, 10~12
N.m

7.

Push the start/stop button (SSB) two
times to turn the ignition ON.
Set the parking brake or place wheel
chocks to prevent vehicle movement.
Press the brake pedal and press the
Neutral button (A) for several seconds
until the cluster displays “N”.
Turn the ignition off.

8.

Remove the retaining clips and remove the air intake duct.
Remove the air cleaner. Refer to Engine Mechanical System, Air cleaner.
Remove the battery. Remove the mounting bracket and bolt. Slide the battery forward to
remove the battery tray. Remove the battery tray and move out of the way to access the
position sensor. Refer to Engine Electrical System, Battery.

For some models:
Use pliers to pinch the tab and disconnect
the harness from the ECM bracket.
Move the ECM bracket out of the way to
access the position sensor.

11.

Press down on the tab and disconnect the
shift by wire (SBW) actuator connector.
Remove 3 bolts and remove the SBW
actuator. Move the actuator out of the way to
access the position sensor.

15.

Confirm the manual valve is horizontal to the
radiator. If not, turn the manual valve to align
with the electronic shift actuator.

16.

Reinstall the SBW actuator.
Install 3 bolts and torque to specification.
Torque: 15~19 lb-ft, 2~3 kgf.m, 21~26 N.m

17.

Reinstall all the removed parts in reverse order of removal.
Reset the preset radio stations.

18.

Clear the DTC and test drive the vehicle for two drive cycles (two key-on to key-off driving
