Generator Lamp

The PCM commands the generator lamp ON under the following conditions:
^ When the engine speed is greater than 1200 rpm and system voltage falls below 10 volts for longer than 10 seconds. The PCM commands the generator lamp OFF when system voltage rises to above 12 volts.
^ When the generator control circuit (L terminal) remains low for longer than 10 seconds.
^ When the engine speed is between 1000 and 1300 rpm and the generator's F terminal duty cycle is greater than 95% for 60 seconds.

OR

^ When the engine speed is between 1000 and 1300 rpm and the generator's F terminal duty cycle is less than 5% for 30 seconds.
