• With the elimination of the voltage regulator, generator control is carried out by the PCM. (See GENERATOR CONTROL OPERATION [LF, L3].) Exciting current in the field coil is increased or decreased by the duty signal from the PCM sent to the power transistor built into the generator.

• The generator warning light in the instrument cluster illuminates under the following conditions. (See DTC DETECTION LOGIC AND CONDITIONS [LF, L3].)

- Charging system voltage problem
- Charging system voltage low
- Charging system voltage high
- IAT sensor circuit low input
- IAT sensor circuit high input
