S TERMINAL CIRCUIT
DescriptionINFOID:0000000001724479
The output voltage of the generator is controlled by the IC regulator at terminal “3” (S) detecting the input volt-
age. Terminal “3” circuit detects the battery voltage to adjust the generator output voltage with the IC regulator.
Diagnosis ProcedureINFOID:0000000001724480
1.CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION
Check to see if connector F2 terminal 3 is clean and tight.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair terminal connection. Confirm repair by performing complete Starting/Charging system test.
Refer to Technical Service Bulletin.
2.CHECK VOLTAGE REGULATOR CIRCUIT
Check voltage between generator harness connector F2 terminal 3
and ground.
Does battery voltage exist?
YES >> Refer to CHG-33, "Work Flow".

< BASIC INSPECTION >[MR18DE]
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.
Te s t r e s u l t
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.INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
Turn the ignition switch ON.
Does the charge warning lamp illuminate?
YES >> GO TO 6
NO >> GO TO 5
5.TERMINAL“2” (OPEN) CIRCUIT INSPECTION
Check terminal “2” circuit for open circuits. Refer to CHG-39, "
Diagnosis Procedure".
Is the terminal
“2” circuit normal?
YES >> Replace generator.
NO >> Repair as needed.
6.INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle.
Does the charge warning lamp turn OFF?
YES >> GO TO 9
NO >> GO TO 7
7.TERMINAL “2”(SHORT) CIRCUIT INSPECTION
Check terminal “2” circuit for short to ground. Refer to CHG-39, "
Diagnosis Procedure".
Is the terminal
“2” circuit normal?
