Shift Light Indicator (M/T)
Shift light indicator is controlled by ECM to indicate shift point to obtain maximum fuel economy based on engine speed and load. The ECM will activate shift light when following conditions are present:
- Both idle switch and wide open throttle switches are off.
- Engine speed is greater than 1500 RPM.
- Vehicle speed is greater than 3 MPH.
NOTE:
Engine speed for shift indicator light operation may vary with intake manifold pressure and coolant temperature.
