5.2 Fault messages in communication protocol to genset control
system
112222 – HI T-Exhaust Mean
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Weighted average of all
individual exhaust gas
temperatures is too high.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
112223 – HIHI T-Exhaust Mean
Red alarm. Initiated by EMU.
Cause
Corrective action
Weighted average of all
individual exhaust gas
temperatures is too high.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
112301 – HI T-Exhaust A1
Yellow alarm. Initiated by EMU.
Cause
Corrective action
The exhaust temperature of this
cylinder is too high as compared
with the average value.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
112302 – HI T-Exhaust A2
Yellow alarm. Initiated by EMU.
Cause
Corrective action
The exhaust temperature of this
cylinder is too high as compared
with the average value.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
112303 – HI T-Exhaust A3
Yellow alarm. Initiated by EMU.
Cause
Corrective action
The exhaust temperature of this
cylinder is too high as compared
with the average value.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
112304 – HI T-Exhaust A4
Yellow alarm. Initiated by EMU.
Cause
Corrective action
The exhaust temperature of this
cylinder is too high as compared
with the average value.
1. Check emission values.
2. Check ignition timing (→ Page 143).
3. Check valve drive (exhaust valves do not close).
