摘要
The invention relates to a method for running diagnostics on an oxidation catalytic converter (40) in an exhaust line (20) for gases (90) emanating from an internal combustion engine (80), the exhaust line (20) comprising a selective catalytic reduction member (60) downstream of the oxidation catalytic converter (40) in the direction in which the gases are exhausted, the method involving measuring the level of nitrogen oxides downstream of the selective catalytic reduction member (60) in the direction in which the gases (90) are exhausted, and determining that the oxidation catalytic converter (40) has failed according to the level of nitrogen oxides measured.
