Understanding OBD2 Cables for Dash Cameras: A Comprehensive Analysis
The integration of dash cameras into vehicles has become increasingly popular, yet concerns persist regarding their installation via OBD2 cables. Many users report issues such as check engine lights and other complications when connecting dash cameras directly to the OBD2 port. This post aims to clarify these concerns by examining different types of OBD2 cables and their potential impact on vehicle performance.
Types of OBD2 Cables
The IROAD OBD2 cable utilizes only two pins: pin 4 for ground and pin 16 for constant power. This configuration minimizes interaction with the vehicle's onboard computer systems, significantly reducing the risk of communication-related issues. Over three years of usage, this cable has not been associated with any reports of check engine lights or malfunctions. The newer models of the IROAD cable, such as the new IM300 version, supports
Electric vehicles and gas. It works on Vueroid, Thinkware, GNET, Fine Vu and of course IROAD.
GNET OBD2 Cable
The GNET cable operates with four pins: pin 4 (chassis ground), pin 5 (signal ground), pin 14 (CAN low), and pin 16 (constant power). While pin 4 and pin 5 are typically safe, as they primarily serve grounding functions, the inclusion of pin 14 introduces potential communication with the vehicle's CAN system. This interaction could lead to issues if the cable is not properly configured. Some users have reported problems when using this cable, although the exact reasons remain uncertain.
The Thinkware cable is more complex, involving eight pins: pin 4 (ground), pin 6 (CAN high), pin 7 (K-line), pin 8 (manufacturer discretion), pin 12 (manufacturer discretion), pin 13 (manufacturer discretion), pin 14 (CAN low), and pin 16 (constant power). The presence of pins dedicated to CAN communication (both high and low) indicates a direct interaction with the vehicle's systems. This communication can lead to complications such as triggering check engine lights. Reports from users highlight issues tied to this specific cable.
Analysis of Potential Challenges
The key factor regarding the occurrence of check engine lights and other problems appears to be the level of interaction with the vehicle's onboard systems. Cables that only draw power and ground—like the IROAD OBD2 cable—show a significantly lower incidence of complications compared to those that engage in two-way communication with the vehicles computer.
The Thinkware cable, while versatile, brings a higher risk due to its multiple connection points with the vehicle’s system. Users have expressed concerns in various forums and communities, highlighting the importance of considering cable specifications before purchase. We have personally installed the Thinkware cable in newer Mazda vehicles without any challenges.
OBD2 Cables for Dash Cameras
In conclusion, while using an OBD2 cable to power a dash camera offers convenience, it is crucial to select the right type to avoid potential challenges. The IROAD OBD2 cable is the safest option, as it minimizes interaction with the vehicle's systems by relying solely on ground and constant power connections. The GNET and Thinkware cables, while functional, present higher risks due to their additional pins and communication capabilities.
