Are you looking to modify your Bafx Products Obd2 Bluetooth Scanner? Many users appreciate the convenience of these scanners for vehicle diagnostics using apps like Turbo3’s. The BAFX Products OBD2 Bluetooth Scanner is well-regarded for its reliable connection and compatibility. For those interested in a simple modification, this guide will show you how to change the power source from constant 12V to switched 12V, ensuring your scanner only draws power when your vehicle is on or in ACC mode. This modification is straightforward and can be completed in about 15 minutes.
Here’s a step-by-step guide to modify your BAFX Products OBD2 Bluetooth Scanner for switched 12V power:
-
Access the Screws: Begin by removing the blue label on your BAFX Products OBD2 Bluetooth Scanner. Underneath this label, you will find four screws that secure the casing. Remove these screws to open the device.
-
Separate the Unit and Disconnect: Carefully separate the two halves of the scanner casing. Once open, you’ll see a white connector plugged into 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 scanner’s shell for easier access to the wiring.
-
Wire Modification: Locate pin 16 and pin 8 on the OBDII connector. Pin 16 is the full-time 12V power supply, and pin 8 is the switched ACC 12V. Carefully move the wire currently connected to pin 16 and insert it into pin 8. On many BAFX Products OBD2 Bluetooth Scanner models, pin 16 is on the top left, and pin 8 is on the bottom left, making this wire move quite simple.
-
Reassemble the Unit: Place the OBDII connector back into the scanner shell and reconnect the white connector to the PC board. Carefully reassemble the two halves of the casing and secure them with the four screws you removed earlier. Be mindful of the five LEDs inside to avoid bending them during reassembly.
-
Final Touches: You can now reapply the blue label or leave it off, depending on your preference.
Your BAFX Products OBD2 Bluetooth Scanner is now modified to operate on switched ACC power. It will function as before, but will only be powered when your vehicle is turned on or in ACC mode. This modification ensures that the scanner does not continuously draw power from your vehicle’s battery when it’s turned off, and it works seamlessly with apps like Turbo3’s for vehicle diagnostics.
