(2) Warm-up Control Function
Low voltage
▶
If low voltage is detected by the ECU, the idle speed increases up to 100 rpm selectively under the
driving mode until the ignition switch is turned off.
Idle speed control
▶
The idle speed is controlled according to the fuel/air mixture when the engine load is changed, the
power steering wheel is turned to its end, the selector lever is in the "D" position and the A/C compressor
is in operation. It is also controlled according to the charge level during the purge control operation.
Ignition timing
▶
The idle speed is controlled according to the fuel/air mixture when the engine load is changed, The
ignition angle can be retarded up to 36˚ or advanced up to 20˚ to help idle speed control.
Air conditioner compressor operation
▶
The air conditioner control unit sends the air conditioner operation signal to the ECU to increase the
throttle valve opening amount in order to prevent reduction of the engine speed when the air conditioner
compressor is in operation at idling.
(3) Warm-up Control Operating Conditions
To make the catalytic converter reach a operating temperature, the ignition timing is retarded for about
20 seconds under the following conditions:
The coolant temperature is 15°C ~ 40°C when the engine is started.
The selector lever is in the "P" or "N" position.
▶
▶
Also, the idle speed increases to 1100 ~ 1500 rpm simultaneously by the idle speed control. However, as
soon as the selector lever is shifted to the D position, warming up control of the catalytic converter will be
inhibited. The information necessary to perform such control is as follows:
Coolant temperature
Engine rpm
Intake air mass
Recognizing idling status
Selector lever position
