3.12.1.5 Yellow TCU-Caution-Light of Manifold-Air-Pressure-Control is
FLASHING
A malfunction of the following systems is possible:
- sensors
- sensor-lines
- Turbo-Control-Unit
- Leakage of airbox
1. CONTROL the RPM and manifold-air-pressure with THROTTLE (red
MAP-warning-light must be OFF).
Recommended operating limits:
75% MCP
(MAP : ≤ 31 inHg, engine speed ≤ 5000 RPM)
2. Turn OFF waste-gate-actuator with TCU-isolation-switch (the red
safety-switch is UP), if manual control is not satisfactory.
3. Lower engine-power has to be expected, when the manifold-air-
pressure-control is not operating correctly.
Caution: If the yellow TCU-caution-light is flashing, this must be
documented by the pilot in the A/C-logbook with details like:
nature of incident, date, duration and the degree of
exceeding.
