2. Välja 'Freeze Frame'.
3. Review the recorded parameters to understand the conditions under which the fault occurred.

4.6 DTC-sökning

This feature allows you to manually enter a Diagnostic Trouble Code and view its definition from the scanner's internal database.

7. Felsökning

7.1 Enheten slås inte på

• Ensure the diagnostic cable is securely connected to the vehicle's OBD2 port.
• Kontrollera att fordonets tändning är i läge 'ON' eller att motorn är igång.
• Check the vehicle's fuse for the OBD2 port (consult your vehicle's owner's manual).

7.2 Kommunikationsfel med fordonet

• Confirm the vehicle is OBDII-compliant (generally 1996 and newer for gasoline vehicles).
• Ensure the diagnostic cable is properly connected.
• Turn off the ignition, wait 10 seconds, then turn it back to 'ON' and try again.
• If possible, test the scanner on another compatible vehicle to rule out a device malfunction.

7.3 Codes Cannot Be Cleared

• Ensure the vehicle's ignition is in the 'ON' position (engine off).
• If the underlying fault that triggered the code is still present, the code may not clear or will reappear immediately. Address the vehicle's issue first.

8. Underhåll

• Rengöring: Använd en mjuk, torr trasa för att rengöra enheten. Undvik slipande rengöringsmedel eller lösningsmedel.
