STIHL® M-Tronic™ Engine Check Segment STIHL DIAGNOSTIC SOFTWARE & MDG1 Troubleshooting If you are having issues using SDS or your MDG1, let’s do a quick check to see what could be causing the issue. MDG1 will not connect to SDS or cannot be found. • Check the LED’s on the MDG1. Green: The MDG1 has power. Blue: The MDG1 is connected and paired via Bluetooth. Pink: The MDG1 is not connected, it needs to be paired. • Access the control panel on your computer. Select Devices and Printers. Look to see if your MDG1 is listed by serial number. If it’s not in your device list, select add device. Windows will guide you through the pairing process. During pairing, you will be asked for the passcode. The passcode is STIHL. Once the MDG1 is paired: Launch the STIHL DIAGNOSTIC SOFTWARE. If the pairing was successful, the serial number of your MDG1 will be displayed when the MDG1 is selected. • If you are still unable to pair your MDG1, try shutting down nearby devices. Other electronic devices might be causing interference. Other scan tools in in the shop might also create conflicts. The building itself might be blocking the signal, try connecting your MDG1 in a different location. Installed PC software might also block access. Does your PC require Administrator access to install a new device? 106

STIHL® M-Tronic™ Engine Check Segment Now that we know our MDG1 is connected to our PC/Laptop- we still may encounter an issue while connecting to our unit. You might get the message: Control Unit Does Not Respond. • Pull the starter rope 3-4 times to provide power to the control unit. • Check the connector pin fit- The MDG1 pins maybe be damaged if connected incorrectly. • Inspect all connections for dirt and debris and clean as needed. • Check the wiring on the unit. Look for broken wires or loose connections. Keep in mind we might have a failed control unit. If a connection is not established at this time, it would be wise to connect a known running unit to your MDG1. If you are still unable to connect to the control module, there could be a PC or SDS software compatibility issue. • Uninstall STIHL DIAGNOSTIC SOFTWARE • Download the latest version of SDS https://dealers.stihlusa.com/Portal Once the latest version of SDS is installed, reboot your computer and try connecting to the unit. For a detailed Troubleshooting manual, please visit: www.bryanequipment.com -Select the TECHNICAL SERVICE tab -Select TECHNICAL RESOURCES -Select STIHL DIAGNOSTIC SOFTWARE USER MANUAL Don’t forget to update your SDS software and MDG1 firmware regularly. New updates are continuously being released. 107
