L1 - Exhaust gas temperature (downstream of the catalytic converter) (°C)
L2 - Exhaust gas temperature (upstream of the catalytic converter) (°C)
M - Post-injection control
Operation with post-injection: the temperature upstream of the catalytic converter
is less than the temperature downstream of the catalytic converter.
