Detailed Flow
- PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to Diagnosis Procedure .
GO TO 2.
- STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
CONSULT
Stop the operation of the power generation voltage variable control in either of the following procedures:
- After selecting "ENGINE", set the DUTY value of "ALTERNATOR DUTY" to 0 % by selecting "ALTERNATOR DUTY" with "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.)
- 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 connector and erase the self-diagnostic results history of the engine.]
