Back–Up Function
If there is trouble with the program in the ECM and the ignition signals (IGT) are not output, the ECM controls
fuel injection and ignition timing at predetermined levels as a back–up function to make it possible to continue
to operate the vehicle.
Furthermore, the injection duration is calculated from the starting signal (STA) and the throttle position signal
(IDL). Also, the ignition timing is fixed at the initial ignition timing, 5° BTDC, without relation to the engine speed.
HINT: If the engine is controlled by the back–up function, the Malfunction Indicator Lamp lights up to warn the
driver of the malfunction but the diagnostic trouble code is not output.
