Check the continuity between the connector pins indicated in the table.
2. Check the overdrive solenoid valve.
A) Disconnect the solenoid valve connector.
b) Measure resistance between leads "1" And "3".
- Rated resistance - 10-16 Ohm
V) When applying for conclusions "1" And "3" connector of the battery voltage solenoid valve, you should hear the click of the activated valve. If there is no click, replace the valve.
G) Connect the solenoid valve connector.
3. Check the continuity, between the terminals "2" And "4" overdrive switch connector. When the mode is on, there should be no conductivity, when it is off, there should be conductivity. Otherwise, replace the switch.
