CHG-6

< BASIC INSPECTION >

[HR16DE]

DIAGNOSIS AND REPAIR WORKFLOW

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done
as a set from start to finish.

PRELIMINARY INSPECTION

Perform the preliminary inspection. Refer to

CHG-37, "Inspection Procedure"

>> GO TO 2

DISABLE THE POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

Disable the power generation voltage variable control with either of the following procedures.
• After selecting “ENGINE” on the “SELECT SYSTEM” screen of CONSULT-III, set the “ALTERNATOR DUTY”

value 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.)

• Turn the ignition switch OFF, disconnect the battery current sensor connector and leave it disconnected dur-

ing the course of the test.

NOTE:
Running the engine with the battery current sensor disconnected will cause DTC's (P1550-P1554) to set.
After finishing the inspection, connect the battery current sensor connector and erase the self-diagnostic
results history of the engine using CONSULT-III.
