Diagnostic Fault Code Erasing

Reliable Diagnostics & Warning-Light Reset Services

When your dashboard warning lights appear — such as EM, ABS, DPF, TRACTION CONTROL, or BRAKE PAD WEAR — it indicates that one or more of your vehicle’s electronic systems has logged a fault. These warning indicators should not be ignored, as they can lead to a fail in NCT/DOE or mask underlying issues.

At KC Systems, we specialise in reading, interpreting, and erasing diagnostic trouble codes (DTCs) across all makes and models, using advanced dealer-level diagnostic tools to deliver accurate, reliable service.

What We Offer

Full System Scan & Fault Code Readout We connect to your vehicle’s ECU(s) and scan all modules — engine, transmission, ABS, chassis, emission, and more — retrieving active and stored fault codes, freeze-frame data and sensor logs.
Detailed Fault Reporting & Diagnostics Advice After reading the codes, we interpret them and provide you with clear, plain-English explanations. Where needed, we advise on repair steps or further investigation.
Warning Light Erasing / Reset Once issues are addressed (or if codes are historical), we can safely clear stored fault codes and reset warning lights — ensuring your vehicle’s diagnostic system starts afresh.
Post-Reset Verification After erasing codes, we carry out a short test cycle to confirm whether the fault recurs. If new faults appear, we re-scan and report.
Intermittent / Historical Code Management Not all faults are persistent. Some are one-time or intermittent events. We can help distinguish current active issues from old history codes to avoid unnecessary repairs.

Why Choose KC Systems for Diagnostic Fault Code Erasing

Advanced Dealer-Grade Tools
We use high-end diagnostic hardware and software to access vehicle modules at the same level as manufacturer systems.
Comprehensive Coverage
Whether petrol or diesel, all makes (European, Asian, US), we are equipped to handle broad system diagnostics.
Transparent & Honest Approach
We never “erase code first, ask questions later.” Every code is recorded before reset so you know exactly what was present.
Avoid NCT / DOE Surprises
Many warning lights can lead to failures on inspection tests. Our reset services help ensure your car is inspection-ready when repairs are completed.
Safeguard Against ECM “Safe Mode”
In some cases, unresolved faults force the vehicle’s control system into default or limp modes. Removing fault codes correctly helps restore normal performance when issues are fixed.

How the Process Works

Step	Description
1. Connect & Scan	We link into the ECU network and read all current and stored trouble codes.
2. Analyze & Report	Codes are interpreted and delivered to you in clear terms, along with recommended actions.
3. Repair (if needed)	You may choose to address faults immediately, later or elsewhere; this is not mandatory for us to erase codes.
4. Erase & Reset	After faults are resolved (or if they are historical), we clear codes and reset the system.
5. Road Test & Verification	We test-drive or simulate conditions to ensure no new faults have reappeared.
