112317 – HI T-Exhaust B7
Yellow alarm. Initiated by EMU.
Cause
Corrective action
Exhaust gas temperature of this
cylinder is too high in comparison
with weighted average.
1. Check emission values (→ Page 47).
2. Check ignition timing (→ Page 176).
3. Check valve drive (exhaust valves do not close).
