DIAGNOSTIC PROCEDURE 2
Check Magnetic Switch Circuit
1. CHECK POWER SUPPLY TO MAGNETIC SWITCH
1. Remove the fuel pump fuse.
2. Crank or start the engine (where possible) until the fuel pressure is released.
3. Turn the ignition switch OFF.
4. Disconnect starter motor connector F28.
5. Check voltage between starter motor connector F28 terminal S
and ground using a digital circuit tester.
OK or NG
OK >> GO TO 2.
NG >> Check the following:

40A fusible link (letter h , located in fuse and fusible
link box)

10A fuse (No. 49, M/T models, located in the IPDM E/
R)

15A fuse (No. 52, located in the IPDM E/R)

20A fuse (No. 53, located in the IPDM E/R)

PNP switch, clutch interlock switch or TCM depending on equipment

Ignition switch

Ignition relay IPDM E/R

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.

fuse
3. CHECK VOLTAGE DROP ON VOLTAGE REGULATOR CIRCUIT
Check voltage between generator connector F1 terminal 3 and bat-
tery positive terminal using a digital circuit tester.
OK or NG
OK >> Replace the generator. Refer to SC-32, "Removal and
Installation" . Confirm repair by performing complete
Battery/Starting/Charging system test.
NG >> Check harness between the battery and the generator
for poor continuity. Battery voltage should exist.

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00I1G
System DescriptionEKS00I1H

Front wiper relays (front wiper relay, front wiper high relay) are located in the IPDM E/R (intelligent power
distribution module engine room).

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R operates wiper motor according to CAN communication signals from BCM.
