The diagnostic socket of the Chery A113 is located inside the armrest box (central storage compartment). Open the armrest box to find a rectangular black cover, beneath which lies the diagnostic socket. The vehicle diagnostic interface is an electrical socket for the On-Board Diagnostics (OBD) system. When connecting, ensure the device is inserted with the power off. The diagnostic card functions when inserted into a PCI slot. Additional Information: The vehicle diagnostic interface consists of 16 pins, each serving a distinct purpose. Typically, Pin 2 is the bus positive, Pin 4 is chassis ground, Pin 5 is signal ground, Pin 7 is the K-line, Pin 10 is the bus negative, Pin 15 is the L-line, while Pin 16 is solely for power supply or detecting battery voltage and current. Also known as a PC-Analyzer or POST (Power-On-Self-Test) card, the diagnostic card operates by displaying error codes generated by the BIOS's internal self-test program. These codes, when cross-referenced with a code meaning quick-reference table, quickly identify computer faults. This tool is particularly useful when the PC fails to boot the operating system, displays a black screen, or the speaker remains silent, showcasing its convenience in troubleshooting.

How Does Light Illumination Change When Encountering Curves?

Below is an introduction to how headlight illumination changes when encountering curves ahead during nighttime driving: Light changes: The illumination will shift from the center of the road to the side; on straight roads, the light distance remains unchanged; when encountering a typical curve, the light follows the turn, moving from the center to the side. When going uphill: The light moves from high to low as the vehicle ascends or descends; when encountering sharp curves or large potholes, the light may leave the road surface due to vehicle jolts. When approaching an intersection: Reduce speed 50 to 100 meters before the intersection, switch from high beam to low beam, and activate the turn signal to indicate the direction of travel. When an oncoming vehicle is within 150 meters: Switch from high beam to low beam to avoid obstructing the other driver's vision.
