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: The incident parts are subject to callback through the normal Warranty Technical Center (WTC) parts return process. Claim is subject to debit if the parts requested are not returned. NOTE 5: 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, All and OK. 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. TSB #: 23-AT-006H-1 Page 3 of 6 SUBJECT: 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. The SBW lever is currently functioning correctly and the related harness currently does not have an open/short. Go to Step 4. • Does not show the correct lever position, the SBW lever or related harness may have a fault. If no damage or loose pins are found with the related harness, replace the SBW lever. 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%. TSB #: 23-AT-006H-1 Page 4 of 6 SUBJECT: AUTOMATIC TRANSAXLE PUSH-BUTTON SHIFTER DIAGNOSIS 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) 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) Tucson (NX4) 2.5L – (VINs begin with KM8) 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. Carefully unwrap the harness protector in the area shown below. Check if the insulation has been damaged by contact with the metal bracket. If so, repair or replace the control harness. TSB #: 23-AT-006H-1 Page 5 of 6 SUBJECT: AUTOMATIC TRANSAXLE PUSH-BUTTON SHIFTER DIAGNOSIS Information 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. NOTICE If replacing the control harness, make sure the replacement harness does not contact the battery tray/other components. Otherwise, the harness may become damaged again. 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. TSB #: 23-AT-006H-1 Page 6 of 6
