183341C2 | Genuine International® Consolidated Engine Controller ECM

1. Simplify engine control

• Replaces multiple independent control units with one integrated controller

• Reduces system complexity, wiring, and interfaces

2. Improve safety

• Continuously monitors engine parameters

• Automatically prevents over-temperature, over-speed, flameout, or surge

• Executes safe shutdowns and fault responses

3. Increase reliability

• Fewer components and connectors → fewer failure points

• Built-in fault detection and redundancy

4. Optimize performance

• Precisely controls fuel, ignition, and variable geometry

• Adapts to altitude, temperature, and load conditions

• Improves fuel efficiency and thrust/power consistency

5. Reduce pilot/operator workload

• Automates start, operation, and shutdown sequences

• Allows “power-lever-to-thrust” operation (especially in aircraft)

6. Enable diagnostics & maintenance

• Logs faults and engine data

• Supports condition-based maintenance and faster troubleshooting

1. Engine won’t start or has failed starts

• No fuel scheduling during start

• No ignition command

• Start sequence aborts with no obvious mechanical cause

2. Erratic engine operation

• Surging or hunting

• Unstable RPM

• Uncommanded power changes

3. Loss of automatic control

• Engine stuck in a fixed power or “limp” mode

• Reversion to manual or backup control

• FADEC/CEC FAIL or DEGRADED indications

4. Abnormal indications

• Incorrect or frozen engine parameter readings

• Parameters that don’t correlate (e.g., fuel flow not matching RPM)

• Sudden warning or caution messages

5. Engine shutdowns or power reductions

• Uncommanded in-flight shutdown (IFSD)

• Automatic power rollback without a real over-limit condition

6. Fault messages & maintenance codes

• Repeated CEC fault codes after reset

• Built-in test (BIT) failures

• Controller won’t pass power-up self-test

7. Communication issues

• Loss of data between engine and avionics

• Intermittent connection faults

• Engine data missing on cockpit displays

8. Environmental sensitivity

• Problems appear after heat, vibration, or moisture exposure

• Intermittent faults that come and go
