| Preconditioning of the vehicle: 1. The vehicles can be tested without preconditioning. Due to safety concerns the engine should be at operating temperature and in proper mechanical condition. 2. Requirements to the preconditioning: i) the engine has reached the operating temperature, this implies that an engine oil temperature of minimum 80 °C or the normal operating temperature as long as it is lower, is measured using a sensor in the dipstick tube, or the checked engine block temperature using an infrared radiation measurement is at least the same as high. In case this measurement is not possible due to the vehicle configuration, then the normal operating temperature of the engine must be determined otherwise, for example by activating the engine fan. ii) The exhaust system is flushed by a minimum of three load free acceleration cycles from idle speed to speed regulation or with an identical process. | With the on-board diagnostic system: - Permitted diagnostic error codes with the on-board diagnostic scan {codes for the NOx-group, 3000 for light duty commercial vehicles} - Connection and communication protocol (standard, voltage, position) - Directory of the diagnosis error code (vehicle classes A, B1 and B2, at the moment only for heavy duty commercial vehicles).
