- INSPECT SOLENOID (SC2) VALVE
- Remove the solenoid (SC2) valve.
*a Solenoid (SC2) Valve Refer to DISASSEMBLY [08/2015 - ]
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Terminal of solenoid (SC2) valve connector - Solenoid (SC2) valve Body 20°C (68°F) 11 to 15 Ω - Connect a positive (+) lead from the battery to the terminal of the solenoid valve connector, and a negative (-) lead to the solenoid body. 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
REPAIR OR REPLACE TRANSMISSION WIRE. Refer to COMPONENTS [08/2015 - ]
Result:
NG
REPLACE SOLENOID (SC2) VALVE. Refer to COMPONENTS [08/2015 - 10/2016] , or refer to COMPONENTS [10/2016 - ]
- Remove the solenoid (SC2) valve.
