steering wheel angle changes sign (between first and second peaks) during the same test run.

       3.3. The lateral displacement of the vehicle centre of gravity with respect to its initial straight path shall be at least 1.83 m for vehicles with a GVM of 3,500 kg or less, and 1.52 m for vehicles with a maximum mass greater than 3,500 kg when computed 1.07 seconds after the Beginning of Steer (BOS).  BOS is defined in paragraph 5.11.6.

       3.3.1. The computation of lateral displacement is performed using double integration with respect to time of the measurement of lateral acceleration at the vehicle centre of gravity, as expressed by the formula:

       An alternative measuring method may be allowed for type approval testing, provided it demonstrates at least an equivalent level of precision as the double integration method.

       3.3.2. Time t = 0 for the integration operation is the instant of steering initiation, known as the Beginning of Steer (BOS).  BOS is defined in paragraph 5.11.6.

       3.4. ESC malfunction detection

        The vehicle shall be equipped with a tell-tale that provides a warning to the driver of the occurrence of any malfunction that affects the generation or transmission of control or response signals in the vehicle's electronic stability control system.

       3.4.1. The ESC malfunction tell-tale:

       3.4.1.1. Shall be displayed in direct and clear view of the driver, while in the driver's designated seating position with the driver's seat belt fastened;

       3.4.1.2. Shall appear perceptually upright to the driver while driving;

       3.4.1.3. Shall be identified by the symbol shown for "ESC Malfunction Tell-tale" below or the text "ESC":

       3.4.1.4. Shall be yellow or amber in colour;

       3.4.1.5. When illuminated must be sufficiently bright to be visible to the driver under both daylight and night-time driving conditions, when the driver has adapted to the ambient roadway light conditions;

       3.4.1.6. Except as provided in paragraph 3.4.1.7., the ESC malfunction tell-tale shall illuminate when a malfunction exists and shall remain continuously illuminated under the conditions specified in paragraph 3.4. for as long as the malfunction exists, whenever the ignition locking system is in the "On" ("Run") position;

       3.4.1.7. Except as provided in paragraph 3.4.2., each ESC malfunction tell-tale shall be activated as a check of lamp function either when the ignition locking system is turned to the "On" ("Run") position when the engine is not running, or when the ignition locking system is in a position between "On" ("Run") and "Start" that is designated by the manufacturer as a check position;

       3.4.1.8. Shall extinguish at the next ignition cycle after the malfunction has been corrected in accordance with paragraph 5.10.4.;

       3.4.1.9. May also be used to indicate the malfunction of related systems/functions, including traction control, trailer stability assist,
