STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variable control in either of the following procedures.
• After selecting “ENGINE” of “SELECT SYSTEM” using CONSULT, set the DUTY value of “ALTERNATOR
DUTY” to 0 % by selecting “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 voltage regulator of the alternator.)
• Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550 -
P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self-diagnosis results history of the engine using CONSULT.]
