Was the transmission temperature within its permitted range? 

• YES 

  Refer to Intermittent fault 

• NO 

  Refer to Checking transmission fluid temperature sensor

• Ignition off
• Transmission connector D disconnected.

  Check the temperature sensor. Measure the resistance between transmission connector D terminals #D7 and #D8.

  The resistance must be 4.5-6 kΩ at 20°C.

Was the resistance OK? 

• YES 

  Refer to Checking transmission fluid temperature sensor 

• NO 

  Refer to Checking the cable and component 

Check the cable between control module terminal #A37 (#A37) and transmission connector terminal #D7 (control module side). Check for an open-circuit according to Open-circuit, permanent faults .

Check the cable between control module terminal #A55 (#A55)and transmission connector terminal #D8 (control module side). Check for an open-circuit according to Open-circuit, permanent faults .

Remedy as necessary.
