Some precautions during the use of OBD2 16 pin to open end cable

When using OBD2 16 pin open-ended tail fiber cables, the following precautions should be taken to ensure safe and stable diagnostic operations and avoid damaging the vehicle or equipment. The following are specific points to note:

Connection and operation specifications

1. Power off connection and disconnection

Before connection: Be sure to turn off the vehicle power (turn off the engine and remove the key). Some models may need to wait for a few minutes until the onboard electronic system is completely asleep to avoid burning out the interface or diagnostic equipment due to live plugging and unplugging.

When disconnecting: First disconnect the diagnostic equipment from the cable, then unplug the cable from the vehicle OBD-II interface to reduce instantaneous current surges.

2. Interface matching and anti misconnection

Confirm interface type: Ensure that the cable plug matches perfectly with the vehicle OBD-II interface (16 pin trapezoidal interface, usually located on the lower left side of the cockpit), and avoid forcefully inserting non-standard or inferior plugs that may cause bent or short circuited pins.

Check pin definition: The OBD-II standard pin function is fixed (such as 1 being customized by the manufacturer and 16 being the positive pole of the power supply). If the cable pin definition is confusing, it may cause communication failures or equipment damage.

3. Avoid excessive bending and pulling

Wiring specifications: Cables should be kept away from high-temperature areas of the engine, moving parts (such as steering columns), and sharp edges to avoid long-term compression or friction that may cause damage to the outer skin or internal cables.

Do not forcefully pull or tug: hold the plug body when inserting or unplugging, rather than pulling the cable; If you need to adjust the length, you can use extension cords or choose cables of appropriate specifications to avoid excessive bending.
