Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Description
The shift solenoid valve 2 and transmission control module are part of the control solenoid valve assembly and are not serviced separately. The shift solenoid valve 2 is a normally closed solenoid valve and controls fluid to the hybrid low, 1-2 clutch boost valve assembly and related clutches. During this diagnostic test, intrusive actions are taken by the transmission control module to test the shift solenoid valve 2 to see if the valve is stuck ON. When in gear 3, gear 4, or EVT 2, if the correct gear ratio is not achieved in a predetermined period of time, the transmission control module commands second gear and if second gear ratio is attained this indicates a stuck ON shift solenoid valve 2 and the DTC will set.
