7. Troubleshooting
If you encounter issues with your udiag CR600 scanner, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | Loose connection to DLC; Vehicle ignition off; Blown fuse in vehicle's OBDII circuit. | Ensure the OBDII connector is firmly seated. Turn vehicle ignition to 'ON'. Check vehicle's fuse box for a blown fuse related to the OBDII port. |
| "LINK ERROR" message displayed. | Communication failure with vehicle's ECU; Incorrect protocol detected. | Verify the ignition is 'ON'. Ensure the connector is secure. Try connecting to a different OBDII-compliant vehicle to rule out scanner fault. |
| Cannot clear codes. | Engine running; Underlying fault still present. | Ensure the engine is off (ignition 'ON'). Address the root cause of the DTCs before attempting to clear them. |
