This is an Xtool Jeep Compass Cable connetcor Jumper Cables (OBD power to battery clip), a type of automotive diagnostic tool. One end is an OBD port (for connecting to the car’s on-board diagnostics system), and the other end is a battery clip (for connecting to the car battery). Its main function is to provide temporary power to the car’s Electronic Control Unit (ECU) when replacing the car battery or disconnecting the battery power, preventing data in the ECU (such as instrument information, fault codes, personalized settings, etc.) from being lost due to power failure, while ensuring the continuity of diagnostic and repair operations.
This is an Xtool Jeep Compass Cable connetcor Jumper Cables (OBD power to battery clip), which belongs to the category of automotive diagnostic tools.
Detailed Functions:
1.Prevent ECU Data Loss
The car’s Electronic Control Unit (ECU) stores a large amount of critical data, such as instrument panel parameter settings, digital clock time, personalized configurations of memory seats/rearview mirrors, and temporary records of vehicle fault codes. When Xtool Jeep Compass Cable connetcor Jumper Cables is necessary to replace the car battery or disconnect the battery power for maintenance, if the power is cut off directly, this data will be erased. One end of Xtool Jeep Compass Cable connetcor Jumper Cables is connected to the car’s OBD (On-Board Diagnostics) port, and the other end is connected to the car battery via clips.Xtool Jeep Compass Cable connetcor Jumper Cables can continuously supply power to the ECU during the battery disconnection period, thereby preventing data loss.
2.Ensure Continuity of Diagnostic and Maintenance Processes
During car diagnostics (such as using a diagnostic tool to read real-time data streams and detect sensor status) or some maintenance operations (such as initializing specific modules), the ECU needs to remain powered to work properly. Xtool Jeep Compass Cable connetcor Jumper Cables can maintain the power supply to the ECU when the battery is disconnected, ensuring that the communication between the diagnostic equipment and the ECU is not interrupted, allowing diagnostic and maintenance operations to proceed smoothly and continuously.
II. How to Choose
1.Match the vehicle’s OBD port type
There are mainly two types of automotive OBD ports: OBD-I (for older vehicle models, with various port styles) and OBD-II (for mainstream vehicle models manufactured after 1996, with a unified 16-pin port). You need to first confirm your vehicle’s port type and select a cable that is compatible with Xtool Jeep Compass Cable connetcor Jumper Cables to avoid unusability due to mismatched ports.
2.Pay attention to power supply stability and protection functions
Prioritize products with overvoltage protection, overcurrent protection, and short-circuit protection. These functions can prevent damage to the vehicle’s ECU or battery caused by abnormal voltage/current. At the same time, check the power supply parameters (such as output voltage and current) marked on the cable, which must match the power supply requirements of the vehicle’s ECU (most vehicle models use 12V; for some special vehicle models, confirmation is required).
3.Choose high-quality materials and craftsmanship
•Xtool Jeep Compass Cable connetcor Jumper Cables is recommended to select cables with pure copper cores, as they have better conductivity and generate less heat, avoiding insufficient power supply caused by poor-quality cores.
•The battery clips should have an insulated and non-slip design to ensure firm contact when clamped to the battery terminals and prevent short circuits.
•The internal terminals of the OBD connector should be tight, and the plugging and unplugging process should be smooth to avoid affecting power supply stability due to poor contact.
4.Select functions based on usage scenarios
If Xtool Jeep Compass Cable connetcor Jumper Cables is only used for regular battery replacement, a basic model is sufficient. If you need to perform frequent vehicle diagnosis and maintenance, you can choose a model with a power display function, which allows real-time checking of the remaining temporary power supply to avoid sudden power failure midway. Some high-end models also support an extension cord design, which is suitable for scenarios where more operating space is needed during maintenance.
