LETTER "S" ACRONYMS/DEFINITIONS
| Acronym | Definition |
|---|---|
| SAW | Spark Angle Word: Timing information sent from the EEC-IV to the EDIS module. This information is used by the EDIS module to calculate final ignition timing |
| SBS | Supercharger Bypass Solenoid or its control circuit |
| SC | SuperCharged |
| SDV | Spark Delay Valve |
| SEFI | Sequential Electronic Fuel Injection: A computer control- led fuel system that distributes atomized fuel through an injector located in each intake port of the engine. Each injector is fired separately & has an individual circuit |
| Self-Test | One of three subsets of the EEC Quick Test: Key On Engine Off, Engine Running, and Continuous |
| SHO | Super High Output |
| Short Circuit | An undesirable connection between a circuit and any other other point |
| SIG RTN | SIGnal ReTurN circuit for all sensor signals (except HEGO) |
| SIL | Shift Indicator Light: A system that provides a visual indication to the driver of a vehicle when to shift to thenext higher gear to obtain optimum fuel economy |
| Solenoid | A wire coil with a moveable core that changes position by means of electro-magnetism when current flow through the coil |
| SPOUT | SPark OUTput signal: Output from EEC-IV processor |
| SS1 | Shift solenoid 1 or its control circuit |
| SS2 | Shift solenoid 2 or its control circuit |
| SS 3/4- 4/3 | Shift Solenoid 3/4-4/3: Output from the EEC-IV processor to the transmission that selects 3rd or 4th gears |
| STAR | Self-Test Automatic Readout: A testing device in which EECand MCU systems output service codes in a digital format |
| STI | Self Test Input: Circuit in the EEC and MCU systems used initiate Self-Test |
| STO | Self Test Output: Circuit in the EEC and MCU systems that transmits service codes (pulses) to either a VOM or STAR tester |
