INFOID:0000000009682025

OVERALL SEQUENCE

Before performing a generator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-

able test probes are necessary for the test.

• Before starting, inspect the fusible link.

CHG-18

< BASIC INSPECTION >

DIAGNOSIS AND REPAIR WORKFLOW

• Use fully charged battery.

DETAILED FLOW

1.

PRELIMINARY INSPECTION

Perform the preliminary inspection. Refer to 

CHG-20, "Diagnosis Procedure"

.

>> GO TO 2.

2.

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” using CONSULT, set the DUTY value of “ALTERNATOR DUTY” to 0 % by select-

ing “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.)

• 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.] 

>> GO TO 3.
