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 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-diagnostic results history of the engine using CONSULT.]
