Recent reports are flooding in regarding newly purchased Konnwei KW-902 OBD2 adapters causing serious issues, including I-Key errors, in Nissan Leaf vehicles. As your trusted source for automotive tech insights at Techcarusa.com, we’ve investigated these claims and uncovered a potentially widespread manufacturing defect that could impact your vehicle’s sensitive systems. Before you even think about making Batx Obd2 Contact with your car using a new Konnwei KW-902, please read this urgent advisory.
The problem stems from a change in the circuit board design in newer Konnwei KW-902 units. Specifically, some of these adapters are being assembled with an incorrect 20-ohm resistor across the CAN bus pins 6 and 14, instead of the required 120-ohm resistor. This seemingly small component error creates a near short circuit on your vehicle’s CAN bus when you establish batx obd2 contact, which is far from ideal and can lead to unpredictable and potentially damaging consequences.
Imagine plugging in what you believe is a helpful diagnostic tool, only to inadvertently introduce a critical fault into your car’s communication network. The CAN bus is the backbone of your vehicle’s electronic control system. It’s not just a passive monitoring port; it’s the network that allows various modules in your car to communicate and function correctly. Shorting the CAN bus through incorrect batx obd2 contact can disrupt essential vehicle operations.
How to Check Your Konnwei KW-902 Adapter
Before you make batx obd2 contact with your vehicle’s OBD2 port using a new Konnwei KW-902, take a moment to perform a simple resistance check. You will need a multimeter to measure the resistance between pins 6 and 14 of the OBD2 connector on the Konnwei KW-902 adapter. The correct resistance should be approximately 120 ohms. If your measurement reads around 20 ohms, your adapter is faulty and should not be used.
We urge you to take this warning seriously. Driving your Nissan Leaf with a shorted CAN bus due to a faulty OBD2 adapter is risky and could lead to unpredictable vehicle behavior. If you experience any unusual symptoms after establishing batx obd2 contact with any OBD2 adapter, immediately disconnect it and have the adapter’s resistance checked.
Several users have already confirmed receiving defective Konnwei KW-902 adapters with the 20-ohm resistor, some sourced from major online marketplaces. Protect your vehicle by verifying your adapter before use. If you find a 20-ohm resistor, return it immediately to the seller and request a replacement with the correct 120-ohm specification.
In conclusion, exercising caution and performing a quick resistance check on your new Konnwei KW-902 adapter before making batx obd2 contact can save you from potential headaches and costly repairs. Stay safe and informed with techcarusa.com.
