Throttle Valve Map
If reverse gear is selected, the system control receives an input signal from the starter lockout/backup lamp switch. This selects a throttle valve map in
the system control. During reverse driving up to approx. half of the pedal travel, the throttle valve opens more slowly. This improves driveability in
reverse.
