A/C COMPRESSOR RELAY CONTROL

M2132034500722

After the A/C switch is turned ON and A/C compres-
sor relay reaches a state where it can turn ON, 
engine-ECU turns ON the A/C compressor relay and 
drives the A/C compressor. In order to prevent 
change in engine speed due to increased load of 
driving the compressor, it controls the A/C compres-

sor relay to drive the A/C compressor after idle-up is 
complete. Also, in order to secure acceleration per-
formance, it turns OFF the A/C compressor relay for 
a fixed amount of time, if the throttle opening angle 
increases beyond a prescribed limit.

ALTERNATOR CONTROL

M2132025000785

During engine idle operation, engine-ECU controls 
duty of conduction between alternator G terminal and 
earth. (G terminal duty is controlled to be the same 
as ON duty of the power transistor inside the voltage 
regulator). If headlights etc. are turned on while 
engine is idling, the consumed current increases 
suddenly, but by gradually increasing the alternator 
G terminal OFF duty, engine-ECU restricts sudden 

increase in alternator output current and output cur-
rent is increased only gradually. (Battery current is 
supplied to the headlamp etc. till alternator produces 
sufficient current.) Thus, engine-ECU prevents 
change in idle speed due to sudden increase of 
engine load.
