NOTE 1: Normal warranty applies.
NOTE 2: Submit claim on Claim Entry Screen as “Warranty” type.
NOTE 3: Refer to the latest Digital Documentation Policy for repair validation requirements.
NOTE 4: If a part is found in need of replacement while performing this TSB and the
affected part is still under warranty, submit a separate claim using the same repair order. If
the affected part is out of warranty, submit a Prior Approval request for goodwill
consideration prior to performing the work.

SERVICE PROCEDURE:

STUI
Refer to the latest Warranty Digital Documentation Policy for repair validation requirements.
1.

Attach a GDS and select Fault Code Searching. Complete a Fault Code search of all vehicle
systems. Record the DTC and description. Delete the DTC.

2.

If DTC are found, refer to DTC list on Page 1 or the related shop manual, E-Shifter or SBW
Control Unit section for repair guidance.
If no DTC are found, go to Step 3.

3.

AUTOMATIC TRANSAXLE PUSH-BUTTON SHIFTER DIAGNOSIS

Start the engine. From the GDS home screen, select Data Analysis and A/T menu and the
parameters shown below. Push the shift buttons to change gears P, R, N and D. If the cluster
and the GDS data shows:
• Correct gear: The TCU received the correct signals from the SBW lever (Push-button
shifter). The Push-button shifter is currently functioning correctly and the related harness
currently does not have an open/short. Go to Step 4.
• Does not show the correct gear: the Push-button shifter or related harness may have a fault.
If no damage or loose pins are found with the related harness, replace the SBW lever
(Push-button shifter).

4. Start the engine. From the GDS home screen, select Data Analysis, SCU menu and the
parameters shown below. Push the shift buttons to change gears. If the GDS data shows:
• Correct Target Lever Position and Actual Lever Position: The SCU commanded the
SBW actuator to shift to the requested gear. The SBW actuator and position sensors 1 and
2 are functioning correctly and the related harness currently does not have an open/short.
Go to Step 5.
• Does not show the correct Target Lever Position: The SCU did not command the SBW
actuator to shift to the requested gear. The SCU or related harness may have a fault.
• Does not show the correct Actual Lever Position: The SBW actuator did not select the
requested gear. The SBW actuator or related harness may have a fault.
NOTE: The Motor Feedback Current should briefly show electrical current when a shift button
is pressed, indicating the SCU sent current to the SBW actuator. If no amps is shown, the SCU
or related harness may have a fault.
NOTE: The sum of Position sensor 1 and 2 should be approximately 100%.

5.

Turn the engine off and push the SSB 2 times to turn the ignition ON. Press the brake pedal.
From the GDS home screen, select Actuation Test and SCU menu. Test the Target position
for P, R, N and D. Press the arrow to change the selection. If the GDS and cluster show:
• Correct Target Position for P, R, N and D: The SCU sent electrical current to the SBW
actuator, the SCU and SBW actuator are currently operating correctly and the related
harness currently does not have an open/short circuit. Go to Step 6.
• Does not show the correct Target Position for P, R, N and D: The SCU, SBW actuator or
related harness may have a fault.

6.

If Steps 3~5 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 7.
For the following vehicles only:
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. NX4 (KM8): Check if the insulation has been
damaged by contact with the metal bracket.
2. NX4A (5NM): Check for broken wires in the
area of the 90 degree bend in the harness. If
so, repair or replace the control harness.

SUBJECT:

AUTOMATIC TRANSAXLE PUSH-BUTTON SHIFTER DIAGNOSIS
NOTICE

If replacing the control harness, make sure the replacement harness does not contact the battery
tray or other components. Otherwise, the harness may become damaged again.
Damage to the wiring harness may still be present, even if there is no external damage to the
harness protector. Even slight damage to the wiring harness can cause these faults.
7.

If Steps 3~5 did not find any faults and the issue cannot be duplicated, the issue may be
intermittent. Call Techline for further advice.

APPENDIX: SBW OPERATION
4 components are required to shift to P, R, N and D.
In addition, the PCM or TCU are required to select the correct transmission solenoids.
