SYNCHROREV MATCH MODE (S-MODE)

System Description


INPUT/OUTPUT SIGNAL CHART







SYSTEM DESCRIPTION

Synchrorev Match mode (S-MODE) controls engine speed at a suitable level from the present to the next gear position. This control is switched by S-MODE switch (S-Mode Switch). When clutch pedal is depressed and shift lever is shifted while S-MODE is being operated, gear position signal is sent to ECM.
ECM calculates target engine speed by gear position signal and vehicle speed signal, and then controls throttle opening angle and ignition timing. When downshift is performed, even if accelerator pedal is not depressed, ECM automatically controls throttle opening angle and increases engine speed. When upshift is performed, ECM controls engine speed so that it does not drop lower than the necessary level that is required after upshifting. Engine speed is controlled according to shifting operation above and driver can perform shifting operation quickly, smoothly, and without shifting shock. When S-MODE malfunction is detected, S-MODE
warning on information display illuminates and S-MODE is automatically cancelled. At this time, S-MODE indicator turns OFF.
