Vehicle preconditioning: 1. Vehicles may be tested without preconditioning. For safety reasons, the engine should be at operating temperature and in satisfactory mechanical condition. 2. Preconditioning requirements: i) The engine has reached operating temperature; for instance, the engine oil temperature measured by a probe in the oil level dipstick tube is at least 80 °C (176 °F) or is at the normal operating temperature as long as it is lower, or the engine block temperature measured using infrared radiation is at least an equivalent temperature. If this measurement cannot be performed due to the vehicle configuration, the establishment of the engine's normal operating temperature may be made by other means, for example by the operation of the engine cooling fan. (ii) The exhaust system is purged by at least three free acceleration cycles (no load from idle up to cut-off speed) or by an equivalent method.
