Amazon listing: Feronix B28 Bluetooth 5.3 OBD2 Scanner, Wireless Diagnostic Tool for Check Light, 1000+ Fault Codes (No ABS/SRS), Professional Code Reader for iOS & Android, Fits 1996+ OBDII Compliant Vehicles
The Feronix B28 is a Bluetooth 5.3 OBD2 scanner that sends data to your iOS or Android phone rather than to a built-in screen. Code RLT8D3FK takes 58% off at checkout, and there is no separate coupon on the listing.
According to the title, it works as a wireless diagnostic tool for the check engine light, with a library of more than 1,000 fault codes. The seller says plainly that it does not cover ABS or SRS systems, so it is aimed at engine and emissions codes. It is described as a professional code reader for 1996 and newer OBDII-compliant vehicles.
If you are looking for the best cheap OBD2 scanner and already carry your phone everywhere, a compact Bluetooth dongle like this keeps the tool small. It suits drivers who want to read a code before a shop visit and used-car shoppers. Add it to your cart, enter the Feronix coupon code at checkout, and make sure the total shows 58% off.

Before you buy the Feronix B28 Bluetooth 5.3 OBD2 Scanner: quick tips
- Read the note that ABS and SRS are not supported, and decide whether engine-only codes are enough.
- Check which app the scanner uses and whether it is free, since the title does not say.
- Confirm your phone's Bluetooth version and OS meet the listing's requirements.
- Locate your OBD2 port under the dash so you know where the scanner will sit.

Feronix B28 Bluetooth 5.3 OBD2 Scanner coupon & promo code FAQ
Does it read ABS and airbag codes?
No. The title says no ABS or SRS, so the scanner focuses on engine and emissions codes. If you need brake or airbag diagnostics, you will need a different tool that lists those systems.
How do I use code RLT8D3FK?
Add the scanner to your cart, go to checkout and enter RLT8D3FK in the promo box for 58% off. The listing shows no clip coupon, so verify the discount in the order summary.
Which phones are supported?
The listing says iOS and Android with Bluetooth 5.3. Check the full page for the name of the companion app and any minimum software requirements before you buy. Also confirm the app is available in your phone store.
Will it work on my car?
It is described for 1996 and newer OBDII-compliant vehicles. Look for a 16-pin port near the driver's footwell, and check your vehicle's year before ordering. The scanner will not read ABS or airbag systems, and some very new or unusual models may behave differently. Confirm against the listing.
Is RLT8D3FK still working?
It was active when we last checked on Oct 23, 2026. Seller codes usually run 24–72 hours or until a set number of uses is gone, so apply it soon. Our team marks a code as ended as soon as members report it.
Is there a Feronix B28 Bluetooth 5.3 OBD2 Scanner coupon or discount code?
Yes – RLT8D3FK is the current Amazon promo code (58% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout.
Do I need Amazon Prime to use it?
No. Promo codes work for any Amazon account unless the promotion box on the product page says Prime-only.
Why didn't the code apply?
Usually a different size or color than the one the code covers, a one-per-account limit, or the code sold out. See all the fixes.
