Why do I need a professional OBD2 scanner?

It can diagnose and clear fault codes, monitor various sensor data, reset the engine warning light, and assist with DIY repairs and modifications. This OBD2 scanner can help you diagnose and resolve vehicle faults more effectively, saving you both time and money.

Read/Clear Fault Codes: Read engine fault codes at the touch of a button; once cleared, the ‘Check Engine’ light will be deactivated, confirming that the issue has been resolved.

View Freeze Frame Data: Retrieve vehicle operating parameters (such as RPM, coolant temperature and vehicle speed) from the moment the fault occurred, enabling precise identification of the root cause.

Read I/M Status: Check the vehicle’s emissions readiness status to help you pass annual inspections and emissions tests with ease.

Retrieve Vehicle Information: Automatically identifies vehicle details such as the VIN and calibration ID, facilitating vehicle management and maintenance records.

Real-time Voltage Monitoring: Monitors battery voltage in real time, detecting signs of battery ageing or low charge in advance to prevent breakdowns on the road.

Wide compatibility: Suitable for most petrol vehicles manufactured after 1996 (US spec), 2001 (EU spec) and 2008 (Asian spec).

Please note: This product is designed specifically for engine system (OBD2) diagnostics. It does not support ABS (Anti-lock Braking System), SRS (Airbag System) or transmission system diagnostics, nor does it support service light resets. If you require these functions, please select an advanced professional scanner.

Extended fault code coverage Includes a built-in lookup database for generic fault codes (P0, P2, P3 and U0) as well as manufacturer-specific fault codes (P1, P3 and U1). The upgraded version features a comprehensive database containing 35,901 DTCs. This far exceeds that of older OBD2 diagnostic tools, which typically cover only 3,000 to 10,000 DTCs. This means this OBD2 diagnostic tool is better equipped to assist with diagnosing and resolving vehicle faults.	Voltage monitoring The Classic Enhanced Universal OBD II Diagnostic Tool can monitor battery voltage in real time, helping you detect signs of battery depletion and ageing at an early stage, thereby reducing the risk of vehicle breakdowns.

Q: Which car makes does this diagnostic scanner support?

A: Compatible with most US vehicles manufactured from 1996 onwards, European vehicles from 2001 onwards, Asian vehicles from 2008 onwards, and newer vehicles with OBD II and CAN protocols. Suitable for domestic and imported petrol vehicles, as well as 30% of diesel vehicles. Pure electric vehicles and new energy hybrid vehicles are not supported. Some vehicles may be unable to connect due to data link compatibility issues.

Q: Can the car scanner scan ABS, SRS or the drivetrain?

A: This car scanner does not support ABS, SRS or the resetting of maintenance warning lights. It focuses solely on the detection and clearing of engine faults. Reading and clearing the ‘Check Engine’ light is very straightforward.

Q: What should I do if the scanner cannot read or clear fault codes?

A: Firstly, please ensure your vehicle supports the OBDII protocol and follow the operating instructions. Furthermore, only engine fault codes can be read or deleted, and fault codes can only be deleted once the fault has been rectified. Fault codes cannot be deleted until the fault has been repaired.

Q: Why can’t the vehicle diagnostic scanner read the VIN (Vehicle Identification Number)?

A: Due to differences between car makes and models, OBD II diagnostic scanners may be unable to read certain VINs. In such cases, it may be necessary to use a diagnostic scanner provided by the specific car manufacturer. Furthermore, the vehicle’s computer system may have been deliberately modified or restricted.
