OK
See step 4
- INSPECT SHIFT SOLENOID VALVE SL3
- Remove the shift solenoid valve SL3.
*1 Shift Solenoid Valve SL3 Refer to DISASSEMBLY [04/2013 - ]
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Terminal 1 of the shift solenoid valve SL3 - terminal 2 20°C (68°F) 5.0 to 5.6 Ω - Connect a positive (+) lead from the battery with a 21 W bulb to terminal 1 and a negative (-) lead to terminal 2 of the shift solenoid valve connector. Check that the valve moves and makes an operating sound.
OK
Valve moves and makes an operating sound.
Result
Proceed to OK NG
Result:
OK
