CONDITION FOR DETECTION: Rpm > THRPM-
GEARDIAG
DETECTION: It is recognized a fault if
VGearPos>VGEARPOSMAX for a time > TGEAR-
SHIFT
Mark: during a gear shift the gear sensor voltage
goes to Vcc. As a voltage equal to Vcc means
short circuit or open circuit it is necessary to use a
timer (TGEARSHIFT) to discriminate the normal
operation from the real fault
