OK:

"Line Pressure" remains OFF when "Line Pressure Solenoid" is ON.

(d) Select the following menu items: Powertrain / Hybrid Control / Trouble Codes.

(e) Check if DTCs are output.

OK:

DTCs are not output.

(f) Select the following menu items: Powertrain / Hybrid Control / Active Test / Control the Shift Position.

(g) Select the following menu items: All Data / B1 Oil Pressure, B2 Oil Pressure, Line Pressure, Line Pressure Solenoid.

(h) Perform the "Control the Shift Position" active test.
(i) Switch the shift position between "Lo" and "Hi" several times using the "Control the Shift Position" active test.

OK:

NOTICE:
Transmission system DTCs may be set if the "Control the Shift Position" active test is canceled before it is completed.
