For Case 3 (intermittent malfunction),

For Case 2 (mechanical malfunction),

In response to the pending failure, S1 valve is retried by triggering S1 valve

command to stroked and back to destroked. If PS1 pressure switch

continues to indicate stroked, then one of three malfunction cases exists:

Acondition which couldlead to a vehicledeceleration above thedesign safety metric. Ifcommanded clutchpressures are above athreshold which wouldallow multiple clutchesto carry torque, theclutch is consideredapplied, otherwise theclutch is consideredreleased.
