conditions specified in paragraph 8. of this Regulation.
5.1.1.  As an alternative to the requirements of paragraph 5.1., vehicles of categories M1 and N1 with a mass in running order of more than 1,735 kg may be equipped with a vehicle stability function which includes roll-over control and directional control and meets the technical requirements and transitional provisions of Regulation No. 13, Annex 21. These vehicles do not need to meet the functional requirements specified in paragraph 6. and the performance requirements specified in paragraph 7. under the test procedures specified in paragraph 9. and under the test conditions specified in paragraph 8. of this Regulation.
5.2. The ESC shall be so designed, constructed and fitted as to enable the vehicle in normal use, despite the vibration to which it may be subjected, to comply with the provisions of this Regulation.
5.3. In particular, the ESC shall be so designed, constructed and fitted as to be able to resist the corroding and ageing phenomena to which it is exposed.
5.4. The effectiveness of the ESC shall not be adversely affected by magnetic or electrical fields. This shall be demonstrated by fulfilling the technical requirements and respecting the transitional provisions of Regulation No. 10 by applying:
                  (a) The 03 series of amendments for vehicles without a coupling system for charging the Rechargeable Electric Energy Storage System (traction batteries);
                  (b) The 04 series of amendments for vehicles with a coupling system for charging the Rechargeable Electric Energy Storage System (traction batteries).
5.5. The assessment of the safety aspects of ESC, with respect to its direct effect on the braking system, shall be included in the overall safety assessment of the braking system as specified in Regulation No. 13-H requirements associated with complex electronic control systems. This is deemed to be fulfilled on the presentation of a Regulation No. 13-H certificate which includes the ESC system to be approved.
5.6. Provisions for the periodic technical inspection of ESC systems
5.6.1. It shall be possible at a periodic technical inspection to confirm the correct operational status by visual observation of the warning signals following a power-on.
5.6.2. At the time of type approval, the means implemented to protect against simple unauthorized modification of the operation of the warning signals shall be confidentially outlined. Alternatively, this protection requirement is fulfilled when a secondary means of checking the correct operational status is available.
  6.  Functional requirements
 Each vehicle submitted for approval pursuant to this Regulation shall be equipped with an Electronic Stability Control (ESC) system that:
6.1. Is capable of applying braking torques individually to all four wheels[4] and has a control algorithm that utilizes this capability;
6.2. Is operational over the full speed range of
