The core function is to disable various systems that can cause mechanical issues or trigger dashboard warning lights.
| Function Category | Specific Features | Purpose & Benefit | | :--- | :--- | :--- | | | DPF (Diesel Particulate Filter) - Disables the regeneration process and associated fault codes. | To allow the physical removal of a failed DPF or to prevent costly regeneration issues, especially for off-road vehicles. | | | EGR (Exhaust Gas Recirculation) - Deactivates the EGR valve. | To prevent carbon buildup in the intake manifold, a common issue in many engines, improving engine cleanliness and longevity. | | | AdBlue/SCR System - Completely disables the selective catalytic reduction system. | To resolve issues with the AdBlue system, such as failed injectors or sensors, while eliminating continuous warning lights. | | | CAT / Lambda Sensor - Disables catalytic converter monitoring. | Used when a catalytic converter is removed or replaced with a non-OEM part, preventing "Check Engine" lights. | | Diagnostic & Security | DTC (Diagnostic Trouble Code) Erase - Clears stored fault codes (Powertrain, Body, Network). | Essential for clearing residual codes after disabling a system (e.g., DPF removal), ensuring a clean ECU status without warning lights. | | | IMMO Off (Immobilizer) - Disables the factory immobilizer for specific engines. | Used in engine swaps or standalone projects where the original key and immobilizer system are not available. | | Performance & Drivability | Vmax (Speed Limiter) Correction - Allows raising or removing the vehicle's top speed governor. | Used primarily for off-road vehicles or on racetracks where factory speed restrictions are not desired. | | | AGS (Active Grill Shutter) / SAP (Secondary Air Pump) Off - Disables these auxiliary systems. | To prevent fault codes from a malfunctioning system or after its physical removal. | | | Valvematic Off - Disables the variable valve lift system for 2ZR and 3ZR engines. | Used when Valvematic components fail or for specific high-performance engine builds. | toyolex 3 software
