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 post and 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 be 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. Only use CCA.
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”.

REPLACE BATTERYReplace 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 Bat-
tery”, then do so. Perform battery test again to confirm repair.
BAD CELL-REPLACEReplace the battery. Perform battery test again with Battery/Starting/Charging system tester
to confirm repair.
GOOD-RECHARGEPerform the slow battery charging procedure. (Initial rate of charge is 10A for 12 hours.) Per-
form battery test again with Battery/Starting/Charging system tester.
CHARGE & RETESTPerform 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.

M/T MODELS
Power is supplied at all times

to starter motor terminal B, and

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

to ignition switch terminal B.
With the ignition switch in the START position, power is supplied

from ignition switch terminal ST

to IPDM E/R terminal 21.
With the ignition switch in the ON or START position, power is supplied

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

to the clutch interlock switch terminal 1.
With the clutch pedal depressed, power is supplied

through the clutch interlock switch terminal 2

to IPDM E/R terminal 35.
Ground is supplied at all times

to IPDM E/R terminals 39 and 59

through body grounds E15 and E24.
If the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN communication lines,
the IPDM E/R grounds the starter relay and power is supplied

through terminal 19 of the IPDM E/R

to terminal S of the starter motor.
The starter motor magnetic switch energizes closing the circuit between the battery and the starter motor. The
starter motor is case ground through the cylinder block. With power and ground supplied, the starter motor
operates.
