SERVICE PROCEDURE:
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.

3.
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%.

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 exists, repair or replace the related harness.
 If no damage or open/short circuit is found, go to Step 7.
7.
FOR Santa Fe (TMA) only:
If the customer comment was either comment listed below, go to Step 9. If not, go to Step 8.
 “Shifter System Malfunction” displayed on the cluster
 DTC P28E214, Shift motor phase UVW circuit open
8.
If Steps 3~5 did not find any faults and the issue cannot be duplicated, the issue may be
intermittent. Refer to HTSS “Fix it Right” under symptom “ATM – Gearshift Control”.
9.
Record the customers radio presets.
Remove the air cleaner, battery and battery
tray.
Check if the harness is in contact with the
battery tray. If so, go to Step 10.

10. If the harness to the SBW actuator is in contact with the battery tray, 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.
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.
