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 Diagnosis IntroductionEHS001UX
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual.

Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace
it with a new one.

Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

HOW TO ERASE SELF-DIAGNOSIS RESULTS
NOTE:
If the memory in “SELF-DIAG [PAST]” is not erased, User mode will continue to show the system mal-
function by the operation of the warning lamp even if the malfunction is repaired completely.

“SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on the CONSULT-II
screen in real time. After the malfunction is repaired completely,
no malfunction is detected on “SELF-DIAG [CURRENT]”.

“SELF-DIAG [PAST]”
Return to the “SELF-DIAG [CURRENT]” CONSULT-II screen by
touching “BACK” key of CONSULT-II and select “SELF-DIAG
[CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in
“SELF-DIAG [CURRENT]” mode.

“TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.
Self-Diagnosis Function (Without CONSULT-II)EHS001V2
The reading of these results is accomplished using one of two modes — “User mode” and “Diagnosis mode”.

NOTE:
Follow the procedures in numerical order when performing repairs. Confirm whether the repair has been suc-
cessful using air bag warning lamp or CONSULT-II after each repair. If malfunction is still observed, proceed to
the next step. When malfunction has been eliminated, further repair work is not required.
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-II—Diagnosis Mode
Refer to GI-38, "CONSULT-II Start Procedure" .
1. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of
SRS is completed. Go to step 2.
If any DTC is detected on “SELF-DIAG [CURRENT]”, the mal-
functioning part has not been repaired completely or another
malfunctioning part is being detected. Go to SRS-23, "
DIAG-
NOSTIC PROCEDURE 2" .
2. Touch “ERASE”.
NOTE:
Touch “ERASE” to clear the memory of the malfunction
(“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is repaired
completely.
3. Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE”
screen. Touch “SELF-DIAG [PAST]”.
