By Emily · Posted . Price confirmed at Amazon on October 31.
- Reads and clears check engine codes, runs EVAP tests, checks battery health, and shows freeze frame data
- Built-in library decodes over 35,901 fault codes
- Works with most gas vehicles made after 1996 (US) with a standard 16-pin OBD2 port
- 2.4-inch color screen, tri-color status lights, and keyboard shortcuts for quick access to reports
- Rated for -22°F to 158°F with a rugged silicone case and 3-foot heat-resistant cable
This is a straightforward plug-and-play code reader rather than a Bluetooth/app-based tool, which keeps it simple but limits it to on-device viewing. It's sold by third-party seller ATDIAG US, and the 40% discount only applies if you remember to clip the coupon on the product page before checkout. At $23.99 it's a solid basic scanner for home diagnostics, not a professional bidirectional tool.
