The following parameters are required:

- Mode, gear-shift position sensor
- Gear-shift position sensor, position
- Gear-shift position sensor, signal A
- Gear-shift position sensor, signal B
- Gear-shift position sensor, signal C
- Gear-shift position sensor, signal PA
- Mode selector, signal MS1
- Mode selector, signal MS2
- Mode selector position
- Mode, mode selector
- Stop (brake) light switch, position
- Kickdown switch, position
- Kickdown position, shifting
- Throttle position (TP) sensor, signal
- Throttle position sensor, position
- Oil temperature sensor, signal
- Oil temperature
