Oil temperature too high
Checking oil temperature
Ignition on.
Go into scrolling values.
Read off transmission oil temperature.
Check that the transmission oil temperature is within its permitted range. Compare with the temperature of the transmission itself.
Вопрос

Checking oil temperature sensor signal cable
Ignition off.
Disconnect gray 2-pin transmission connector. For further information about connectors, seeru-RU0900c8af80441937#KC01406040.
Connect an ohmmeter between the gray 2-pin transmission connector terminal 2 (transmission side) and transmission housing.
Вопрос
The ohmmeter should read infinite resistance.

Check cable between transmission connectors:
terminal 2 and control module #34 (Fenix 5.1)
terminal 2 and control module #33 (EMS 2000)
for a short-circuit to ground according toru-RU0900c8af80be4147#KC01106352.
Вопрос
Select Continue when the fault has been remedied.
Replacing component
Try a new oil temperature sensor according toru-RU0900c8af8047da89#KC01411708.
Вопрос
Select Continue when the fault has been remedied.
Checking cables and terminals
Check cable between oil temperature sensor and control module:
#34 (Fenix 5.1)
#33 (EMS 2000)
for an intermittent short-circuit to ground according toru-RU0900c8af80854dc2#KC01107969.
Вопрос
Select Continue.

Checking the transmission
Install gray 2-pin transmission connector.
The diagnostic trouble code (DTC) may have been caused by the transmission being subjected to high loads and high temperatures. Therefore it is important to change the oil and check the operation of the transmission.
Change oil according toru-RU0900c8af80442c03#KC01411728.
Test-drive the car as described inru-RU0900c8af80919d9c#KC01627329, to check that there arenomechanical faults.
Вопрос
Does the transmission have any mechanical faults?

Fault-tracing information
Transmission is OK.
Вопрос
Select Continue.
Repairing mechanical faults
Terminate current fault-tracing. Add mechanical symptoms to the symptoms list and fault-trace the symptoms. If the transmission oil has not already been changed during corrective action, change according toru-RU0900c8af80442c03#KC01411728.
Вопрос
Select Continue when the fault has been remedied.
