to front combination lamp RH terminal 2 via
daytime light relay 1 terminals 3 and 4
through grounds E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.
Daytime Light System Operation
With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting
the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via
the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located
in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power
from daytime light relay 1 terminal 3
to front combination lamp RH terminal 2,
through front combination lamp RH high beam terminal 1
to IPDM E/R terminal 56,
through 10A fuse (No. 34, located in IPDM E/R) and
through both de-energized headlamp high relays
to 10A fuse (No. 35, located in IPDM E/R),
through IPDM E/R terminal 55
to front combination lamp LH terminal high beam 1.
Ground is supplied
to front combination lamp LH terminal 2
through grounds E15 and E24,
to daytime light relay 1 terminal 1
through IPDM E/R terminal 6.
With power and ground supplied, high beam headlamps illuminate at reduced intensity.

BATTERY
Revision: June 20062007 Versa
CHARGING THE BATTERY
CAUTION:
Do not “quick charge” a fully discharged battery.
Keep the battery away from open flame while it is being charged.
When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark.
If battery electrolyte temperature rises above 55°C (131°F), stop charging. Always charge battery
at a temperature below 55°C (131°F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be
replaced.
Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00IAZ
CAUTION:
When working with batteries, always wear appropriate eye protection.
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.
If battery surface charge is detected while testing, the tester will prompt you to turn on the headlights to
remove the surface charge.
If necessary, the tester will prompt you to determine if the battery temperature is above or below 0°C
(32°F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to
make the selection.
