Setup
- Locate the vehicle's 16-pin OBDII Data Link Connector (DLC). This is usually located under the dashboard on the driver's side.
- Ensure the vehicle's ignition is in the 'ON' position (engine can be off or running, depending on the test).
- Plug the KW850's OBDII cable into the vehicle's DLC. The device will power on automatically.
Operating Instructions
Navigate through the menu using the arrow buttons and confirm selections with the 'OK' button.
- Reading Codes: Select 'Diagnostic' from the main menu, then 'Read Codes' to view current, pending, or permanent DTCs.
- Erasing Codes: After resolving a fault, select 'Erase Codes' to clear the DTCs and turn off the Check Engine Light.
- Live Data: Select 'Data Stream' to view real-time sensor data. This can be displayed graphically for easier analysis.
- I/M Readiness: Select 'I/M Readiness' to check if all emission monitors have completed their diagnostic cycles.
