The ANCEL BD310 is a palm-sized OBD-II code reader with a 2-inch colour screen and an attached cable that also pairs over Bluetooth with a free iOS or Android app. Car and Driver named it its best overall OBD-II scanner, praising the mix of corded and Bluetooth use, an excellent app interface and an 18.6-second time to display a code. Tom's Guide found it read a deliberately introduced fault, cleared the check-engine light and doubled as a supplementary dashboard gauge. It suits DIY owners who want to read and clear codes and watch live data; anyone needing bidirectional tests or repair guidance should look at more advanced tools.

Strengths
  • — Works as a wired handheld, a Bluetooth phone scanner or a dashboard gauge
  • — Showed a trouble code 18.6 seconds after plug-in in Car and Driver's test
  • — Car and Driver judged its companion app interface excellent
Watch-outs
  • — Small 2-inch screen and four-key interface can feel limiting
  • — No bidirectional control for active component tests
  • — Lacks charging-system and starter tests, and gives no repair information

The BlueDriver Bluetooth Pro is a plug-in OBD2 dongle that works through a free iPhone and Android app. Automoblog, which tested it on a 2017 Ford Fusion Hybrid, rates it 4.5 out of 5 and praises an interface that goes from fault code to probable cause to suggested repair. The outlet's reservations are limited data for European cars and owner complaints that live data refreshes slowly.

Strengths
  • — Interface is "one of the sleekest we've tested," per Automoblog
  • — Reads codes, looks up the probable cause and points to the fix, per Automoblog
  • — Reads enhanced codes such as ABS, SRS and TPMS, per Automoblog
Watch-outs
  • — Limited data for European cars, per Automoblog
  • — Owners quoted by Automoblog say live data refreshes too slowly, one citing five seconds
  • — Requires a smartphone with Bluetooth; no screen of its own, per Automoblog

BlueDriver Bluetooth Pro
