Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00IB2
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. Turn off all loads on the vehicle electrical system.
2. Perform battery test with Battery/Starting/Charging system
tester. Refer to SC-6, "
Trouble Diagnoses with Battery/Starting/
Charging System Tester" .
3. Press “ENTER” to begin the starting system test.
4. Start the engine.
5. Diagnosis result is displayed on the tester. Refer to SC-18,
"DIAGNOSTIC RESULT ITEM CHART" .
NOTE:
If the starter performs normally but the engine does not start,
perform engine diagnosis.
For intermittent “NO CRANK” or “NO STARTER OPERA-
TION” incidents, refer to SC-21, "
DIAGNOSTIC PROCE-
DURE 2" .

Starter relay IPDM E/R
Starter relay request ON signal from BCM
Harness for open or short circuit
2. CHECK VOLTAGE DROP ON MAGNETIC SWITCH CIRCUIT
1. Connect starter motor connector F28.
2. Check voltage between starter motor connector F28 terminal S
and battery positive terminal using a digital circuit tester.
OK or NG
OK >> Magnetic switch circuit is OK. Further inspection is nec-
essary. Refer to SC-19, "
WORK FLOW" .
NG >> Check harness, components and connections between
the battery and the magnetic switch for poor continuity. Ignition switch in

CHARGING SYSTEM
Revision: June 20062007 Versa
CHARGING SYSTEMPFP:23100
System DescriptionEKS00IB3
The generator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times to generator terminal 3 through
10A fuse (No. 29, located in the fuse and fusible link box).
Power is supplied through terminal 1 to charge the battery and operate the vehicle's electrical system. Output
voltage is monitored at terminal 3 by the IC regulator. The charging circuit is protected by the 120A fusible link
[letter a , located in the fusible link box (battery)].
Ground is supplied
to generator terminal 5
through body ground F5, and
through the generator case to the cylinder block
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 3, located in the fuse block (J/B)]
to combination meter terminal 28 for the charge warning lamp.
The IC regulator controls ground to terminal 38 of the combination meter through terminal 2 of the generator.
When the ignition is turned on and power becomes available at terminal 2, this "wakes up" the regulator. The
regulator monitors charge output and grounds terminal 2 or leaves it open depending on charge output. With
power and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient
voltage, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00IB5
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. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press “ENTER” to begin the charging system test.
4. Start engine.
5. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.
NOTE:
If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.
Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect
this without any other action being taken. If this occurs, con-
tinue on with the testing process. The final results will not be affected.
7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the follow-
ing electrical loads.
Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.
Headlamp high beam

NOTE:
Do not run the windshield wipers or any other cyclical loads.
9. Press “ENTER” to continue.
