An OBD cable helps facilitate communication between diagnostic and vehicle systems and helps perform OBD diagnostics. As such, OBD cables perform far more complex and important functions than simple data conduit. Omitting the OBD cable from the diagnostic equipment will result in a loss of communication between the equipment and the vehicle. Consider a scenario where a phone conversation takes place with a broken line; the outcome will be a distorted version of the original discussion. A lower quality OBD cable is similar to this conversation where a dozen phones get in the loop. Using such cables can undoubtedly lead to data loss, lag time, or “incorrect" diagnostics. This will in turn skew the “real" condition of the vehicle. Therefore, OBD cables lose their “low level" title since they become more important than the OBD diagnostics themselves.
The wiring harness is another Element as critical as OBD Cables to maintain OBD system stability. In an automobile, the Wiring harness integrates multiple electrical parts, including the OBD interface. If the Wiring harness is properly designed, it can prevent the inner wires from interference from external elements like temperature changes, vibrations, and moisture. The protection is critical in OBD diagnostics because any disturbance to the Wiring harness can deteriorate signals sent through the OBD Cable. For instance, if the Wiring harness is reliable, the OBD Cable is able to perform its function seamlessly. However, if the Wiring harness is defective, exposed inner wires can lead to short-circuits or signal distortion which impedes the OBD system from collecting accurate information on the vehicle. Hence, an OBD Cable system heavily relies on the Wiring harness.
Using improper OBD Cables or Wiring harness can bring a lot of risks to OBD diagnostics. For OBD Cables, if they don’t meet industry standards, they may have poor conductivity. This means the data between the diagnostic tool and the vehicle will be incomplete. Mechanics will fail to note vital fault codes, resulting in unaddressed vehicle problems. For Wiring harness, if they are not designed for the specific vehicle model, they may not fit properly. Loose connections in the Wiring harness result in diagnostics where the signal has been ‘dropped’ and lost. There are instances where the diagnostic tool is unable to ‘see’ the vehicle OBD system, which means a significant amount of time has been lost. In the worst case, faulty OBD Cables or Wiring harness will impact the vehicle onboard computer and consequentially cause much more damage.
Each scenario and each vehicle model is likely to have unique needs for OBD Cables and for Wiring harnesses. This is the point of custom solutions. Custom OBD Cables, for example, can be made to particular specifications for the vehicle and diagnostic tool's pinout configurations and specific lengths of cables used. This guarantees the best size with proper data flow and transmission. For example, some heavy-duty vehicles may require longer OBD Cables for easier access to the diagnostic port. Custom solutions can satisfy this requirement. Custom Wiring harnesses can be changed to fit the shape and electrical configuration of different vehicles. Depending on the vehicle's operational environment, they can be made with materials designed to withstand high temperatures or corrosion. The custom OBD Cables and Wiring harnesses not only enhance the reliability of OBD diagnostics, but also minimize the chances of compatibility challenges.
When purchasing an OBD Cable and Wiring Harness, the first item to checkout is the quality. Pay attention to products that undergo intense quality control, such as 100% continuity testing. This ensures an OBD Cable is conductive and has no hidden faults. For Wiring harness, make sure the materials used are automotive grade— the harness must be strong enough to endure the extreme conditions inside an automobile. After that, check to see if any customs options are offered. If the vehicle is a particular type, or if the diagnostic OBD work has specific requirments, custom OBD Cables and Wiring harness will be a better fit. Additionally, identify any suppliers that promise rapid prototyping and production. This will help if you are in need of a custom OBD Cable or Wiring harness, so it will not delay the diagnostic work. Lastly, check the reputation of the supplier. It is much more likely that a supplier who has been in the industry for more than 5 years, will have more reliable products, than a new one.
