Frequently Asked Questions

Q: Which vehicles is this OBD2 scanner compatible with?

A: This OBD2 scanner is compatible with all OBD2/EOBD compliant vehicles, which includes most petrol and diesel cars, SUVs, and light trucks made after 1996 (USA), 2001 (Europe), and 2005 (Asia). It supports all five OBD2 protocols: CAN, ISO9141-2, KWP2000, J1850 PWM, and J1850 VPW.

Q: Do I need a battery or any software to use this scanner?

A: No batteries or additional software are required. This OBD2 code reader is a true plug-and-play device — it draws power directly from your vehicle's OBD2 diagnostic port (typically located under the dashboard on the driver's side). Simply plug it in and start diagnosing.

Q: Can this scanner turn off the Check Engine Light (CEL)?

A: Yes! Once you have identified and resolved the underlying issue causing the fault code, you can use this scanner to clear the Diagnostic Trouble Code (DTC) and turn off the Check Engine Light. Note that if the underlying problem is not fixed, the light may reappear.

Q: What is I/M Readiness and why does it matter?

A: I/M Readiness (Inspection & Maintenance Readiness) shows whether your vehicle's emission monitors have completed their self-tests and are ready for an official smog or emissions inspection. Using this feature before heading to an emissions test can save you from a failed inspection and unnecessary return trips.
