- Shift range in except P, N or R range (ATX)
- Neutral switch and clutch switch are OFF (MTX)
- Load is above 40%
- Engine speed is 2, 000 rpm or above
- Brake switch is OFF
Without ABS HU/CM MTX
- Vehicle speed signal from vehicle speed sensor is below 3.7 km/h {2.3 mph}
when following conditions are met:
- Neutral switch and clutch switch are OFF
- Load is above 40%
- Engine speed is 2, 000 rpm or above
- Brake switch is OFF
Diagnostic support note
