GO TO 2
.
- CHECK DTC
CONSULT Select "Self Diagnostic Result" mode of "ENGINE". Is any DTC detected?
YES>>
Refer to DTC Index .
NO>>
GO TO 3
.
- 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" 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.)
- 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 "Self-Diagnostic Results" history of "ENGINE".]
