112222 – HI T-Exhaust Mean
Yellow alarm. Initiated by EMU.
Cause
Corrective action
The average value of all
individual cylinder exhaust
temperatures is too high.
1. Check emission values.
2. Check ignition timing (→ Page 137).
3. Check valve drive (exhaust valves do not close).

Red alarm. Initiated by EMU.
Cause
Corrective action
The average value of all
individual cylinder exhaust
temperatures is too high.
1. Check emission values.
2. Check ignition timing (→ Page 137).
3. Check valve drive (exhaust valves do not close).
