Common Workflows Using D.S. 20
Scenario 1: A customer returns a chainsaw that starts but dies under load.
- Technician action: Connect MDG 1, launch D.S. 20. Run live data while cutting.
- Observation: Fuel solenoid duty cycle spikes to 95% then drops to 0%.
- Diagnosis: The solenoid is drawing too much current and overheating. The ECU shuts it down.
- Solution: Replace solenoid, run guided calibration via D.S. 20. Problem solved.
Current Hardware: The software works with the MDG 1 (Master Diagnostic Gateway) and ADG 2 diagnostic tools. STIHL Diagnostic Software 2
