Engine Control Module
The Electronic Control Module (ECM), through various input sensors, monitors air intake air temperature, atmospheric pressure, coolant temperature, engine RPM and exhaust oxygen content. ECM uses this input information to control fuel injection and operation of other output devices.
ECM has a self-diagnostic function, which allows unit to store a number of trouble codes in its memory. If a failure exists, ECM will inform the driver by turning on Malfunction Indicator Light (MIL) on instrument cluster.
ECM LOCATION
| Application | Location |
|---|---|
| 1.6L | Below Center Of Instrument Panel, Mounted On Floorboard |
NOTE:
Components are grouped into 2 categories. The first category covers INPUT DEVICES, which control or produce voltage signals monitored by ECM. The second category covers OUTPUT SIGNALS, which are components controlled by ECM.
