About ECU Error Clear: OBD2 Catalyst

AUTOMATIC CATALYTIC CONVERTER ERROR FIX

Tired of the constant Check Engine light caused by recurring P0420/P0430 codes? ECU Error Clear is the 1st app designed for fully automatic, hands-free clearing of catalytic converter efficiency codes.

Designed primarily for gasoline engines with catalytic converters, it provides a reliable and safe solution to the most common non-critical catalyst efficiency codes. It is specifically optimized for gasoline engines with LPG conversion and cars that experience frequent, non-critical catalyst errors.

EXCLUSIVE BENEFITS:
★ No Ads, No Distractions: Designed to run silently in the background without draining your battery or data with annoying advertisements.
★ Set and Forget: Once configured, the application handles everything automatically.

SPECIFIC FEATURES:
ͦ Automatic Clearing: Works fully in the background - no manual intervention needed.
ͦ Specific Codes: Targets P0420 and P0430 catalytic converter efficiency codes ONLY.
ͦ Smart Safety: Only clears P0420/P0430 when no other codes are present.
ͦ LPG Optimized: Advanced optimization logic included for gasoline engines with LPG conversions.

ADVANCED SAFETY SYSTEM:
Unlike generic code readers, our smart safety system strictly follows a "no other errors, no action" principle:
1. Scans for ALL diagnostic problem codes (DTCs) before any action is taken.
2. Automatically TERMINATES clearing if any codes other than P0420/P0430 are detected.
3. Guarantees no clearing of critical safety codes (brakes, engine management, airbags, etc.).
4. Operation is BLOCKED unless ONLY P0420/P0430 codes are present.

TECHNICAL SPECIFICATIONS:
ͦ Compatibility: Designed for Gasoline Engines with catalytic converters (Optimization for LPG conversions included).
ͦ Adapter: Requires a high-quality ELM327 Bluetooth OBD2 adapter.
ͦ ͦ Recommended: Bluetooth 4.0 / BLE adapters for best connection stability and auto-sleep functionality.
ͦ ͦ Supported: Standard Bluetooth adapters (ELM327 v1.5 with PIC18F25K80 chip is highly recommended for stability).
ͦ Codes: P0420, P0430 (catalyst efficiency only).
ͦ Operation: Full background automation.
ͦ Internet: Not needed for diagnostics (License check only).
ͦ Android: 8.0+ (Oreo and newer).

SMART LOGGING SYSTEM:
ͦ Complete history of all cleared P0420/P0430 codes with timestamps.
ͦ Configurable checking intervals (set your preferred frequency).
ͦ Detailed diagnostic session records.
ͦ View connection status and ECU responses in real-time.

HOW IT WORKS:
1. Connect your ELM327 OBD2 Bluetooth adapter once.
2. Set your preferred checking interval (e.g., check each Five minutes).
3. Application operates fully automated in the background.
ͦ If ONLY P0420/P0430 codes are show → Automatic clearing is performed.
ͦ If ANY other codes are show → Safety lock is immediately engaged, and NO action is taken.
4. All actions are logged locally on the device.

TARGET AUDIENCE & USAGE INFO:
Target Audience: The app is a technical diagnostic tool intended for users of legal age and/or those authorized to perform car technical maintenance and operation.
Important Usage Information: An internet connection is NOT needed for diagnostics and reading error codes. An internet connection is needed only for the 1st license activation and rare background license status checks.

IMPORTANT SAFETY NOTES:
ͦ This application is for NON-CRITICAL catalytic converter codes ONLY.
ͦ Will NOT clear any other error codes for safety reasons.
ͦ Does NOT fix mechanical problems or replace faulty components.
ͦ Android device Requirement: Due to OS changes (Android 6.0+), the application requires Location/Nearby Devices permission to scan for the Bluetooth adapter. (The application DOES NOT track your actual GPS location).
ͦ Always consult a professional mechanic for serious car issues.
ͦ Not responsible for car hurt or safety issues.
