Enable Conditions
  • Battery voltage is higher than 10V
  • Engine speed higher than 400 RPM
  • Vehicle speed is higher than 50km/h
  • Shift lever position in "D" or "Sports" (Forward gear)
Threshold Value

Fail Safe
  • Prior to fault confirm: Gear fixed at current range, output speed backup signal is fixed at 5th gear
  • After fault confirm: Manual gear shift from 2nd to 5th is allowed Gear is fixed at 5th gear at 'D"

Output speed back-up signal output adaptive
