• Ignition off
• Check the control module and transmission connectors. Check for contact resistance and oxidation according to Contact resistance and oxidation . Remedy if necessary
• Reconnect the control module and transmission connectors
• Ignition on
• Read off the oil temperature.

  Check that the temperature is within its permitted range.

  Compare with the transmission temperature.

  If the transmission temperature is within its permitted range, the cause of the fault was contact resistance or oxidation in the control module or transmission connector.
