The Standards (e) and (f) may be used as an option instead of (a) not earlier than
January 1, 2019.
6.5.3.3. Test equipment and diagnostic tools needed to communicate with OBD systems shall
meet or exceed the functional specification given in the standard listed in
Paragraph 6.5.3.2.(b) of this Appendix.
6.5.3.4. Basic diagnostic data, (as specified in Paragraph 6.5.1.) and bi-directional control
information shall be provided using the format and units described in the standard
listed in Paragraph 6.5.3.2.(a) of this Appendix and must be available using a

Annex 11, Paragraph 2.10., amend to read:
"2.10. A "driving cycle" consists of engine start-up key-on, a driving mode where a
malfunction would be detected if present, and engine shut-off key-off."
Annex 11, Paragraph 3.8.1., amend to read:
"3.8.1. The OBD system may erase a fault code and the distance travelled and freeze-frame
information if the same fault is not re-registered in at least 40 engine warm-up cycles

Sections 7.5.1.(a)–(c) of Annex 11, Appendix 1 are met."
Annex 11, Appendix 1, Paragraph 1., amend to read:
"1. INTRODUCTION
This Appendix describes the procedure of the test according to Paragraph 3. of this
Annex. The procedure describes a method for checking the function of the On-Board
Diagnostic (OBD) system installed on the vehicle by failure simulation of relevant
systems in the engine management or emission control system. It also sets
procedures for determining the durability of OBD systems.
The manufacturer shall make available the defective components and/or electrical
devices which would be used to simulate failures. When measured over the Type I
Test cycle, such defective components or devices shall not cause the vehicle
emissions to exceed the limits of Paragraph 3.3.2 by more than 20%. For electrical
failures (short/open circuit), the emissions may exceed the limits of Paragraph 3.3.2.
by more than 20%.
When the vehicle is tested with the defective component or device fitted, the OBD
system is approved if the MI is activated. The OBD system is also approved if the MI
is activated below the OBD threshold limits."
Annex 11, Appendix 1, insert a new Paragraph 6.1.1., to read:
"6.1.1. The Type I test need not be performed for the demonstration of electrical failures
(short/open circuit). The manufacturer may demonstrate these failure modes using
driving conditions in which the component is used and the monitoring conditions are
encountered. These conditions shall be documented in the type approval
documentation. "
Annex 11, Appendix 1, insert a new Paragraph 6.2.3., to read:
"6.2.3. The use of additional preconditioning cycles or alternative preconditioning methods
shall be documented in the type approval documentation."
Annex 11, Appendix 1, Paragraph 6.3.1.5., amend to read:
6.3.1.5. Electrical disconnection of the electronic evaporative purge control device (if
equipped and if active on the selected fuel type).

Annex 11, insert a new Paragraph 3.10., to read:
"3.10. Additional Provisions for Vehicles Employing Engine Shut-off Strategies.
3.10.1. Driving Cycle
3.10.1.1. Autonomous engine restarts commanded by the engine control system following an
engine stall may be considered a new driving cycle or a continuation of the existing
driving cycle."
Annex 11, insert a new Paragraph 3.2.3., to read:
"3.2.3. Identification of deterioration or malfunctions may be also be done outside a driving
cycle (e.g. after engine shutdown)."
Annex 11, delete Paragraphs 3.3.4.9. and 3.3.4.10.
Annex 11, insert new Paragraphs 3.3.5.1. and 3.3.5.2., to read:
"3.3.5.1. The following devices should however be monitored for total failure or removal (if
removal would cause the applicable emission limits to be exceeded):
(a)
(b)
(c)
A particulate trap fitted to compression ignition engines as a separate unit or
integrated into a combined emission control device;
A NO after-treatment system fitted to compression ignition engines as a
separate unit or integrated into a combined emission control device;
A Diesel Oxidation Catalyst (DOC) fitted to compression ignition engines as a
separate unit or integrated into a combined emission control device.
3.3.5.2. The devices referred to in Paragraph 3.3.5.1. shall also be monitored for any failure
that would result in exceeding the applicable OBD threshold limits."
