CHARGING THE BATTERY
CAUTION:
Never “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. Never 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
Never 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 Diagnosis with Battery/Starting/Charging System Tester (Battery)AKS0079A
CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and alternator 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 headlamps 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.

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery terminals, reconnect them and restart the test.
3. Connect the red tester lead clamp to the positive battery termi- nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys, select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5. Locate the battery type and rating stamped or written on the
top case of the battery to be tested.
NOTE:
The battery rating will have either of the following.
CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)
JIS: Japanese Industrial Standard.
When using the battery tester: Use the CCA rating only.
The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.
U.S. market : Refer to the latest “Battery Testing” Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.
You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating. NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Use only the CCA choice .
7. Press “ENTER” to begin the test. Diagnosis results are dis- played on the tester. Refer to SC-8, "

8. Press “ENTER”, then test output code is displayed. Record the
test output code on the repair order.
9. Toggle back to the “DIAGNOSTIC SCREEN” for test results. NOTE:
If necessary, the tester will ask the user to determine if the
battery has just been charged. Choose the appropriate selec-
tion by pressing the up or down arrow button and then press
the “ENTER” button to make the selection.
When testing a battery installed in a vehicle that has recently
been driven, select “BEFORE CHARGE”.
If the battery has just been slow charged due to a “CHARGE
& RETEST” decision by the tester, and the tester asks the user “BEFORE CHARGE/AFTER
CHARGE”, select “AFTER CHARGE”.

Battery/Starting/Charging System Tester (Starting)" .
REPLACE BATTERY Replace battery.
Before replacing battery, clean the battery cable clamps and battery posts. Perform battery test again with
Battery/Starting/Charging system tester. If second test result is “Replace Battery”, then do so. Perform battery
test again to confirm repair.
BAD CELL-REPLACE Replace the battery. Perform battery test again with Battery/Starting/Charging system tester to confirm repair.
GOOD-RECHARGE Perform the slow battery charging procedure. (Initial rate of charge is 10A for 12 hours.)
CHARGE & RETEST Perform the slow battery charging. (Initial rate of charge is 10A for 12 hours.)
Perform battery test again with Battery/Starting/Charging system tester to confirm repair.
NOTE:
If the tester asks the user “BEFORE CHARGE/AFTER CHARGE”, select “AFTER CHARGE”.

STARTING SYSTEMPFP:23300
System Description AKS0079C
Power is supplied at all times
through 40A fusible link (letter F, located in the fuse and fusible link block)
to ignition switch terminal 1,
through 15A fuse (No. 78, located in the IPDM E/R)
to CPU of IPDM E/R,
through 10A fuse (No. 71, located in the IPDM E/R)
to CPU of IPDM E/R.
When the selector lever in the P or N position, power is supplied
from TCM, and through A/T assembly terminal 9
to IPDM E/R terminal 53.
Ground is supplied
to IPDM E/R terminals 38, 50 and 60
from grounds E21, E50 and E51.
With the ignition switch in the START position, and provided that the IPDM E/R receives a starter relay ON sig-
nal from the CAN lines, the IPDM E/R is energized and power is supplied
from ignition switch terminal 5
to IPDM E/R terminal 4 and
through IPDM E/R terminal 3
to starter motor terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.
