SERVICE PROCEDURE:
STUI
Refer to the latest Warranty Digital Documentation Policy for requirements.
1.
Start the engine.
2.
Attach a GDS and check for DTC in the “Automatic Transaxle” menu. Record the DTC and
description. Delete the DTC.
3.
Select Data Analysis, A/T menu and Current Gear. Depress the brake pedal and move the
shift lever through all gears (P, R, N and D) and monitor the Current Gear. Confirm the GDS
and the indicator on the cluster shows all gears. Turn the ignition OFF.
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 and position sensor (inhibitor switch) 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.
If Steps 3~6 do not show a fault, visually check the wiring harness between the PCM or TCU
and transmission for a damaged wire or open/short circuit. Check for a damaged pin or pin
not fully inserted into the connector.
• If damage or open/short circuit is found, repair or replace the related harness.
• If no damage or open/short circuit is found:
✓ For Santa Fe (TMa) 2.5L or Tucson (NX4/NX4A) 2.5L vehicles, continue to the section
below.
✓ For all other vehicles, go to Step 8.
Santa Fe (TMa) 2.5L – VINs begin with 5NM
Carefully unwrap the harness protector in the
area shown below. Check the insulation on
the wires to see if the insulation has been
damaged by contact with the battery tray. If
so, repair or replace the control harness.
Tucson (NX4/NX4A) 2.5L –VINs KM8 or 5NM
Carefully unwrap the harness protector in the
areas shown below:
1. Check if the insulation has been damaged
by contact with the metal bracket.
2. Check for broken wires in the area of the
90 degree bend in the harness.
If so, repair or replace the control harness.

sure the replacement harness does not
contact the battery tray/other
components. Otherwise, the harness may
become damaged again.
8.
