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 140).
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 140).
3. Check valve drive (exhaust valves do not close).
112301 – HI T-Exhaust A1
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values.
2. Check ignition timing (→ Page 140).
3. Check valve drive (exhaust valves do not close).
112302 – HI T-Exhaust A2
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values.
2. Check ignition timing (→ Page 140).
3. Check valve drive (exhaust valves do not close).
112303 – HI T-Exhaust A3
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Individual exhaust gas
temperature of this cylinder is too
high in comparison with weighted
average.
1. Check emission values.
2. Check ignition timing (→ Page 140).
3. Check valve drive (exhaust valves do not close).
