4. 设置和初始连接
4.1 Connecting the Device to Your Vehicle
The MUCAR CS90 connects to your vehicle via the OBDII port, also known as the Data Link Connector (DLC). This is a standard 16-pin port where diagnostic tools interface with the vehicle's onboard computer.
- Locating the DLC: In most vehicles, the DLC is typically found within 12 inches (approximately 30 cm) of the center of the dashboard, usually under or around the driver's side.
- 备选地点： If the connector is not under the dashboard, a label might indicate its location. In some Asian and European vehicles, the DLC may be located behind the ashtray, which might need to be removed for access.
- 指导： If you cannot locate the DLC, refer to your vehicle's service manual for specific guidance.

- Mode 6: System Monitoring: Retrieves results of on-board diagnostic monitoring tests for specific components/systems.
- Mode 7: Read Pending DTCs: Displays diagnostic trouble codes detected during the current or last driving cycle that are not yet confirmed.
- Mode 8: Control Operation of On-Board System: Allows control of on-board system components or tests.
- Mode 9: Read Vehicle Information: Retrieves vehicle information such as VIN, Calibration ID (CALID), and Calibration Verification Number (CVN).
- Mode 10: Request Emissions-Related Diagnostic Trouble Codes with Permanent Status: Requests emissions-related DTCs with permanent status after a clear/reset of emission-related diagnostic information.
