SEAT SLIDE
"PAST OUTPUT FAIL"

If the following conditions are met, the 
seat sliding output system is judged mal-
functioning. If there is no manual input in 
the past or any auto operation output, and 
then within 2.5 seconds the sliding sensor 
receives an input signal showing that the 
seat has slid by 6 mm or more.

SEAT RECLINING
"PAST OUTPUT FAIL"

If the following conditions are met, the 
seat reclining output system is judged 
malfunctioning. If there is no manual input 
in the past nor any auto operation output, 
and then within 2.5 seconds the reclining 
sensor receives an input signal showing 
that the seat has reclined by 2.22 or more.

If the following conditions are met, the 
steering tilt output system is judged mal-
functioning. If there is no manual input in 
the past nor any auto operation output, 
and then within 2.5 seconds the steering 
tilt sensor receives an input signal show-
ing that the steering wheel is tilted by 1
