Nissan Tiida C11. Manual — part 107
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.
1.
PRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to
CHG-37, "Inspection Procedure"
.
>> GO TO 2
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.
>> GO TO 3
3.
DIAGNOSIS WITH STARTING/CHARGING SYSTEM TESTER
Perform the charging system test using Starting/Charging System Tester (J-44373). For details and operating
instructions, refer to Technical Service Bulletin.
Test result
CHARGING SYSTEM NOMAL>>Charging system is normal and will also show “DIODE RIPPLE” test result.
NO CHARGING VOLTAGE>>GO TO 4
LOW CHARGING VOLTAGE>>GO TO 12
HIGH CHARGING VOLTAGE>>GO TO 14
DIODE RIPPLE NORMAL>>Diode ripple is OK and will also show “CHARGING VOLTAGE” test result.
EXCESS RIPPLE DETECTED>>Replace the generator. Perform “DIODE RIPPLE” test again using Starting/
Charging System Tester (J-44373) to confirm repair.
DIODE RIPPLE NOT DETECTED>>GO TO 4
4.
