Are you looking to optimize the performance of your BAFX Products OBD2 adapter in your Nissan vehicle? Many users prefer their OBD2 adapters to be powered only when the ignition is on, rather than drawing power continuously. This modification, often referred to as a “switched power mod,” is surprisingly simple and can be completed in under 15 minutes with basic tools. This guide will walk you through the process of modifying your BAFX Products PIC18F2480 Bluetooth OBD2 adapter for switched 12V power, specifically tailored for Nissan vehicles.
This modification ensures that your BAFX OBD2 adapter only draws power when your Nissan is running or in ACC mode, preventing potential battery drain when the vehicle is off. The BAFX adapter is known for its compatibility and solid connection, making it a popular choice for users of apps like Turbo3’s app. Its relatively large size is also advantageous, providing ample space for easy access and modifications.
Here’s how to easily convert your BAFX OBD2 adapter to switched ACC power in your Nissan:
-
Access the Internals: Begin by removing the blue label on your BAFX OBD2 adapter to reveal the four screws underneath. Unscrew these to open the casing.
-
Disconnect the Connector: Carefully separate the two halves of the unit. You’ll see a white connector linking the OBDII connector to the PC board. Gently unplug this white connector.
-
Remove the OBDII Connector: With the connector unplugged, you can now lift the OBDII connector assembly completely out of the adapter’s shell. This provides clear access for the next step.
-
Relocate the Power Wire: Locate pin 16 and pin 8 on the OBDII connector. Pin 16 typically carries full-time 12V power, while pin 8 is designated for switched ACC 12V power. In most configurations, pin 16 is on the top left, and pin 8 is on the bottom left, making the wire move straightforward. Carefully move the wire from pin 16 to pin 8. This is the core of the switched power modification.
-
Reassemble the Connector: Place the OBDII connector back into the shell and firmly replug the white connector back into the PC board, ensuring a secure connection.
-
Close the Casing: Reassemble the two halves of the shell and secure them with the four screws you removed earlier. Be mindful of the five LEDs during reassembly to avoid bending them.
-
Final Touches: You can now reapply the blue label or leave it off, depending on your preference.
After completing these steps, your BAFX Products OBD2 adapter will now operate on switched power in your Nissan vehicle. It will function exactly as before, but will only be powered when your car is turned on or in ACC mode. This modification is fully compatible with apps like Turbo3’s App and effectively prevents unnecessary battery drain.
By following this simple DIY guide, you can easily modify your BAFX OBD2 adapter for switched power in your Nissan, enhancing its efficiency and ensuring it only draws power when needed. This quick modification provides peace of mind and optimizes the use of your BAFX Products OBD2 adapter with your Nissan vehicle.
