  NOTE: The N range indicator lamp on the combination meter flashes when the temperature reaches approximately 125°C or higher, and then stops flashing when the temperature drops below approximately 115°C.
3. Replace the sensor if not within the standard value.

2. Use jumper wires to connect the A/T control relay terminal (2) to the battery (-) terminal and terminal (4) to the battery (+) terminal.
3. Check the continuity between the terminal (1) and the terminal (3) of the A/T control relay when the jumper wires are connected to and disconnected from the battery.

SOLENOID VALVE CHECK
1. Use the scan tool (MUT-II) to measure the ATF temperature, and set the ATF temperature to 20°C (68°F).
2. Remove the solenoid valve harness and oil temperature sensor connector.

3. Measure the resistances between the applicable solenoid valve terminals.
4. Check that the values measured in steps 1 and 3 are within the following standard value range.
  Standard value:

5. If the values are within the range, check the power supply and the ground circuit.
6. If the values are outside the range, drain the ATF and remove the valve body.
7. Disconnect the connectors of each solenoid valve.

8. Measure the resistance between terminals 1 and 2 of each solenoid valve.
  1. Standard value: 2.7 - 3.4 ohm (at 20°C (68°F)

9. If the resistance is not within the standard value, replace the solenoid valve.
10. If the resistance is within the standard value, check the solenoid valve harness and the oil temperature sensor connector. If the above procedure indicates that there is no problem with the resistance and the harness, check and replace the solenoid valve O-ring.
