Components
| Component | Description |
|---|---|
| K20 Engine Control Module | The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly. |
| KR75 Engine Controls Ignition Relay | Relays are used to control a high power circuit with a low power signal. |
4 ignition voltage circuits supply the ECM. The 4 circuits are supplied by 2 relay(s):
- KR73 Ignition Main Relay
- KR75 Engine Controls Ignition Relay
The ECM monitors and compares the voltages supplied by the relay(s).
