923 – AL_HI2_T_Exh_SCRsys_outl_F1
Cause
Corrective action
The exhaust gas temperature after
SCR outlet 1 / flow 1 at sensor
B85.6 has violated limit value 2.
The exhaust gas temperature is
too high.
1. Reduce power.
2. Contact Service.
924 – AL_HI1_T_Exh_SCRsys_inl_F2
Cause
Corrective action
The exhaust gas temperature
before SCR inlet 2 / flow 2 at
sensor B85.5 has violated limit
value 1. The exhaust gas
temperature is too high.
1. Reduce power.
2. Contact Service.

942 – AL_LO1_NOx_conversion_SCRsys_F1
Cause
Corrective action
The aging compensator for the
NOx setpoint value integrated in
the ECU logic has reached its limit
value. Satisfactory operation of
the A side catalytic converter is
no longer possible.
