Check the ATF level when the engine is idling in "N" according to TSB 01-40-013. Adjust the ATF level as needed.
2.
Attach the Hi-Scan Pro and check for Diagnostic Trouble Codes (DTC) in both the "ENGINE" and "AUTOMATIC TRANSAXLE" menus. If the
DTC shown are found, follow the repair procedure shown. If no DTC are found, go to Step 3.

Using the Hi-Scan Pro, select "HYUNDAI VEHICLE DIAGNOSIS", "AUTOMATIC TRANSAXLE" and "CURRENT DATA" menus, then
"OIL TEMPERATURE" or "FLUID TEMPERATURE". Confirm the oil temperature readout is correct as shown. If not, replace the oil
temperature sensor.
