Wide Vehicle Compatibility
The ANCEL AD310 is designed to work with most cars, light trucks, minivans, and SUVs sold in North America from 1996 onwards, including many European and Asian models post-2000. This broad compatibility makes it a versatile choice for owners of various vehicles.

Read and Clear Check Engine Codes
With this scanner, you can quickly read diagnostic trouble codes (DTCs) to identify problems triggering your vehicle's check engine light. Importantly, it allows you to clear these codes, turning off the warning light once issues are resolved. This can save costly trips to the mechanic for basic diagnostics.
