Insert new Paragraphs 2.2.1. to 2.2.2.3., to read:
"2.2.1. Operating Sequence
2.2.1.1. For vehicles that employ engine shut-off strategies that are commanded by the engine
control system (for example hybrid bus with engine shut-off at idle) and that are followed by
an engine cranking, the (engine shut-off – engine cranking) sequence shall be considered
as part of the existing operating sequence.
2.2.1.2. The manufacturer shall provide the description of such strategies in the documentation
considered in Paragraphs 3.1.3. (a) and 3.1.3. (b) of this Regulation.
2.2.1.3. In the case of a hybrid vehicle, the operating sequence shall start at the time of the engine
start or at the time when the vehicle starts moving, whichever occurs first.
2.2.2. Driving Cycle
2.2.2.1. For vehicles that employ engine shut-off strategies that are commanded by the engine
control system (for example hybrid bus with engine shut-off at idle) and that are followed by
an engine cranking, the (engine shut-off – engine cranking) sequence shall be considered
as part of the existing driving cycle.
2.2.2.2. The manufacturer shall provide the description of such strategies in the documentation
considered in Paragraphs 3.1.3. (a) and 3.1.3. (b) of this Regulation.
2.2.2.3. In the case of a hybrid vehicle, the driving cycle shall start at the time of the engine start or
at the time when the vehicle starts moving, whichever occurs first."
Paragraph 2.3.2.2., amend to read:
"2.3.2.2. In the case of a wall flow diesel particulate filter (DPF), until the date specified in
Paragraph 13.2.3. of this Regulation for new type approvals and Paragraph 13.3.3. for new
registrations, the manufacturer may choose to apply the performance monitoring
requirements set out in Appendix 8 to Annex 9B instead of the requirements of
Paragraph 2.3.2.1., if he can demonstrate with technical documentation that in case of
deterioration there is a positive correlation between the loss of filtration efficiency and the
loss of pressure drop ("delta pressure") across the DPF under the operating conditions of
the engine specified in the test described in Appendix 8 to Annex 9B."

Table 2, amend to read:
"Table 2
OTLs (Positive Ignition Engines)
Annex 9B
Paragraph 3.5., amend to read:
"3.5. "Continuous-MI" means the malfunction indicator showing a steady indication from the
time the key is moved to on (run) position and the engine is started (ignition on – engine on)
or the vehicle starts moving, whichever occurs first, and extinguishing when the key is
moved to off."
Paragraph 3.22., amend to read:
"3.22. "Short-MI" means the malfunction indicator showing a 15s steady indication from the time
the key is moved to on (run) position and the engine is started (ignition on - engine on) or
the vehicle starts moving, and extinguishing either after these 15s or when the key is moved
to off, whichever occurs first."
Paragraph 4.6.4., amend to read:
"4.6.4. MI activation at Key-on/Engine-off
The MI activation at key-on/engine-off shall consist of two sequences separated by a 5s MI
off:
(a)
(b)
The first sequence is designed to provide an indication of the MI functionality and the
readiness of the monitored components;
The second sequence is designed to provide an indication of the presence of a
malfunction.
The first sequence starts from the first time the system is at key-on position and stops either
at its normal completion or when the key is set to the key-off position, whichever occurs first.
The second sequence is repeated until either the engine is started
moving, or the key is set to the key-off position, whichever occurs first.
, the vehicle starts

level.
4.2.2.3. Repair and maintenance of LNG Type A dual-fuel engines and vehicles.
In the case of LNG Type A dual-fuel engines and vehicles, the manufacturer may, instead of
limiting the vehicle speed at 20km/h, opt for limiting the power of the engine to 20% of the
declared maximum power in dual-fuel mode, and this at any engine speed, when the service
mode is activated during a repair or maintenance operation.
4.2.2.3.1. The power limitation option may only be activated if the system concludes that the gas tank
is empty not later than 5min after engine cranking, the engine being at idle.

tank is empty from a previous driving cycle and the gas tank has not been refilled.

only be activated during a repair or maintenance operation."
