A shift must not be in progress; an selector lever position, pressure switch, or watchdog
test must not be in progress; no spike must be detected from the solenoid during the first
test, or a pressure switch problem, or a speed problem. The code sets if the solenoid continuity
test failed for the second time, or if there is either a pressure switch or speed data problem
and the solenoid continuity test failed for the first time.
