Function "OBD" stands for "On-Board Diagnostics," the standardized diagnostic interface for motor vehicles. The OBD Emissions Module is a compact electronic device that is simply plugged into this diagnostic interface. There, it monitors the engine control unit's error memory in real time for possible entries. If an impending error is detected in the memory, the OBD Emissions Module blocks it before the driver sees a message in the cockpit. Expected, sporadically occurring error codes can be isolated. If an unexpected error occurs, the deletion process stops. This preserves the functionality of the error memory. Error codes The OBD Emissions Module is self-learning and can generally block all exhaust-related error codes. During installation, the module learns the entered codes as expected errors. This process can be repeated as often as desired to add further error codes. Manufacturer-specific codes that do not comply with the OBD standard are also deleted. As soon as an unexpected error occurs, the OBD Emissions Module no longer intervenes. This ensures that the full functionality of the error memory and engine warning light is retained for all other error messages. Application You can use the OBD Emissions Module on vehicles from model year 2008 onwards that comply with the European EOBD standard or implement it accordingly. There are also vehicles that already support the necessary standard in previous years. You can recognize these vehicles by the fact that pins 6 and 14 are occupied on the diagnostic connector. It does not matter whether the engine runs on diesel, gasoline, natural gas, or LPG. Some engine control units do not support the deletion of error codes while driving using the OBD protocol. The OBD Emissions Module is not suitable for these vehicles. Please check this before placing your order. Installation The OBD Emissions Module is simply plugged into the vehicle's OBD socket. Vehicle change When changing vehicles, you can continue to use the OBD Emissions Module for vehicles built in 2008 or later without any problems. If the module detects a new chassis number after installation, all learning values are reset. The OBD Emissions Module is then virtually brand new.
