For enthusiasts and professionals alike, having an Obd2 Ii Eobd Car Diagnostic Auto Scanner V1.4 is an invaluable tool. These scanners allow you to tap into your vehicle’s computer, reading diagnostic trouble codes, monitoring performance, and much more. Many users appreciate the convenience of Bluetooth-enabled adapters like the BAFX Products PIC18F2480, known for its solid connection and compatibility with apps like Turbo3’s.
However, some users prefer their OBD2 II EOBD car diagnostic auto scanner v1.4 to only be powered when the ignition is on or in accessory mode, rather than drawing power continuously. This modification to switched 12V power is surprisingly simple and can be completed in about 15 minutes with basic tools. This guide will walk you through the process using the popular BAFX Products PIC18F2480 Bluetooth OBD2 adapter as an example.
-
Start by removing the four screws that secure the adapter’s casing. These screws are located beneath the blue adhesive label. Carefully peel off the label to access and remove the screws.
-
Gently separate the two halves of the adapter’s casing. Once open, you’ll see a white connector linking the OBDII connector to the internal PC board. Unplug this white connector.
-
With the connector unplugged, you can now completely remove the OBDII connector from the adapter’s housing. This provides easy access for the next step.
-
The key to this modification is relocating the power wire. Locate pin 16, which provides constant 12V power, and pin 8, which is switched 12V ACC power. Simply move the wire currently in pin 16 to pin 8. On the BAFX adapter, pin 16 is on the top left, and pin 8 is on the bottom left, making this a straightforward move.
-
Place the OBDII connector back into the housing and reconnect the white connector to the PC board.
-
Reassemble the two halves of the casing and secure them with the four screws. Be mindful of the internal LEDs during reassembly to avoid bending them.
-
Finally, you can reapply the blue label or leave it off, depending on your preference.
Your OBD2 II EOBD car diagnostic auto scanner v1.4 adapter is now modified! It will function exactly as before, but will only receive power when your vehicle is turned on or in accessory mode. This switched power setup works seamlessly and is fully compatible with applications like Turbo3’s App, ensuring you can diagnose your vehicle’s health only when needed, saving power and potentially preventing battery drain.
