The failure is duplicated. Go to step 3.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between line pressure solenoid valve A and the PCM.?
3.
Determine possible failure area (line pressure solenoid valve A, others):

Determine possible failure area (line pressure solenoid valve A, others)
?1.
Press the engine start/stop button to select the OFF mode.

?2.
Disconnect the following connector.

?3.
Connect terminals A and B with a jumper wire.
Terminal A
Line pressure solenoid valve A 2P connector No. 1 (YEL)
Terminal B
Body ground


?4.
Press the engine start/stop button to select the ON mode.

?5.
Clear the DTC with the HDS.


?6.
Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported, and allow the front wheels to rotate freely.

?7.
Start the engine.

?8.
With the brake pedal pressed, shift to D, then release the brake pedal.

?9.
