(4) ESP OFF switch monitoring
When the ESP unit recognizes that the ESP OFF switch is pushed for over 60 seconds, the ESP unit determines it as
a ESP OFF switch malfunction. When the ESP OFF switch is pushed, the ESP system is resumed after 60 seconds.
However, the ESP warning lamp comes on when the ESP OFF switch is pushed (for over 150 ms) and then goes out
when the ESP system is resumed. When the ESP OFF switch returns to normal position, the ESP unit resets the ESP
OFF switch for approx. 3.5 seconds.
