Electronic Control Assembly (ECA)

The EEC-IV processor determines spark angle using the Profile Ignition Pick-up (PIP) signal to establish base timing. Spark Output (SPOUT) is sent from the EEC-IV processor to the Distributorless Ignition System (DIS) module and serves two purposes; the leading edge fires the coil and the trailing edge controls the dwell time. This feature is called Computer Controlled Dwell (CCD). For diagnosis and testing of EEC-IV related components (Coolant Sensor, Throttle Position Sensor, Knock Sensor ...... etc.) refer to COMPUTERIZED ENGINE CONTROLS.
