Product Information
Full details
The Laser 7728 OBDII/EOBD Fault Code Reader is designed for vehicle owners and DIY mechanics seeking to diagnose and clear engine trouble codes. Its key benefit is the ability to quickly identify the cause of a check engine light and reset it, saving diagnostic time and potential workshop fees. A key caveat is that it only addresses OBDII/EOBD engine codes and will not reset other vehicle warning lights such as service, ABS, or SRS.

Extended Product Information
FAQs
What does OBDII/EOBD compliant mean?
OBDII (On-Board Diagnostics II) and EOBD (European On-Board Diagnostics) are standardized systems required on vehicles to monitor emissions-related components and systems. Compliance ensures that diagnostic tools like the Laser 7728 can communicate with the vehicle's computer.
Can this reader reset my car's service reminder or oil light?
No, the Laser 7728 is designed specifically for reading and clearing engine trouble fault codes and turning off the Malfunction Indicator Light (MIL). It cannot reset service lights or oil life monitors.
What types of vehicles is this code reader compatible with?
It is compatible with Petrol vehicles from 2001 onwards and Diesel vehicles from 2004 onwards, provided they are OBDII/EOBD compliant.
How do I clear a fault code?
After reading and identifying the fault code, and assuming the underlying issue has been addressed, navigate to the 'Clear Codes' option on the device menu. Confirm the action when prompted. The 'Check Engine' light should then turn off.
What is the Malfunction Indicator Light (MIL)?
The MIL, commonly known as the 'Check Engine' light, is an indicator on your dashboard that illuminates when the vehicle's onboard diagnostic system detects a problem with the engine, emissions system, or other related components.
Can I use this reader on my ABS or airbag warning lights?
No, this reader is limited to OBDII/EOBD engine codes and will not diagnose or clear fault codes related to Anti-lock Braking Systems (ABS), Supplemental Restraint Systems (SRS, airbags), or other specific vehicle modules.
What if the code reader doesn't fit my OBDII port?
Ensure you are connecting to the correct OBDII diagnostic port on your vehicle. The standard 16-pin connector on the reader should fit any standard OBDII port. If there appears to be physical damage or obstruction, do not force the connection.
Troubleshooting
Device does not power on or display any information.
Ensure the vehicle's ignition is turned ON (engine can be off). Verify the OBDII port is clean and the connector is securely plugged in. Check if the vehicle is within the compatible model year range.
Reader cannot communicate with the vehicle's ECU.
Confirm the vehicle is OBDII/EOBD compliant and within the specified model years (Petrol 2001+, Diesel 2004+). Try a different OBDII port if available (rare) or try on another compatible vehicle to rule out a reader fault.
Codes are displayed, but the 'Check Engine' light does not turn off after clearing.
The underlying issue may not have been fully resolved, or the system may require multiple drive cycles for the light to extinguish. Ensure all repairs are complete and consult vehicle-specific repair manuals if the light persists.
Reader displays 'No Codes Found' but the MIL is on.
This could indicate a non-OBDII related fault, a fault in a system not covered by this reader (e.g., ABS, SRS), or a specific type of emission-related code that this reader cannot access. Consult a professional diagnostic tool or mechanic.
