2.STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variabl e control in either of the following procedures.
• After selecting “ENGINE” using CONSULT, set the DUTY value of “ALTERNATOR DUTY” to 0 % by select-
ing “ALTERNATOR DUTY” of “Active Test”. Continue “Active Test” until the end of inspection. (When the
DUTY value is 0 or 100 %, the normal power generation is performed according to the characteristic of the
IC regulator of the generator.)
• Turn the ignition switch OFF, and disconnect the batte ry current sensor connector. [However, DTC (P1550–
