ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
Maintenance-Free Battery:
If under the lower level, replace the battery (or add distilled wa-
ter if possible). and check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, turn the ignition switch ON and turn on the electrical
system (headlight, blower motor, rear defogger etc.) for
60 seconds to remove the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) Measure the battery voltage between the negative (-)
and positive (+) terminals of the battery.
Standard voltage:
12.5 - 12.9 V at 20°C (68°F)
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.

Check the pending fault code using the Continuous
Test Results function (Mode 7 for SAE J1979) on the
OBD II scan tool.
(b) Clearing the DTCs using the OBD II scan tool or the
hand-held tester.
(1) Connect the OBD II scan tool or the hand-held tes-
ter to the DLC3.
(2) Turn the ignition switch ON.
(3) Erase DTCs and freeze frame data with the OBD II
scan tool (complying with SAE J1978) or the hand-
held tester. For the hand-held tester: 1) enter the
following menus: DIAGNOSIS / ENHANCED OBD
II / DTC INFO / CLEAR CODES; and 2) press YES.
For the OBD II scan tool, see its instruction manual.
(c) Clearing the DTCs not using the OBD II scan tool or the
hand-held tester.
Remove the EFI or ECD No. 1 and ETCS fuses from the
engine room J/B for more than 60 seconds, or disconnect
the battery terminal for more than 60 seconds.
After disconnecting the battery terminal, perform the ºINI-
TIALIZE procedure.
3. DTC CHECK (Check Mode)
HINT:
Hand-held tester only:
Check mode has a higher sensitivity to detect malfunctions and
can detect malfunctions that normal mode cannot detect.
Check mode can also detect all the malfunctions that normal
mode can detect.
(a) Follow these steps when preparing to use the hand-held
tester check mode.
(1) Make sure that the items below are true:

Battery positive voltage 11 V or more

Throttle valve fully closed

Transmission in the P or N position

A/C switched OFF
(2) Turn the ignition switch OFF.
(3) Connect the hand-held tester to the DLC3.
(4) Turn the ignition switch ON.
(5) Change the ECM to check mode with the hand-
held tester. Enter the following menus: DIAGNOSIS
/ ENHANCED OBD II / CHECK MODE. Make sure
the MIL flashes as shown in the illustration.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand-held tester is used to change the ECM from
normal mode to check mode or vice-versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or OFF.

(6) Start the engine. The MIL should turn off after the
engine starts.
(7) Simulate the conditions of the malfunction de-
scribed by the customer.
(8) After simulating the malfunction conditions, use the
hand-held tester diagnosis selector to check the
DTC, freeze frame data and other data.
(9) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clearing DTCs using the OBD ll scan tool or the hand-
held tester.
(1) Connect the OBD ll scan tool or the hand-held tes-
ter to the DLC3.
(2) Turn the ignition switch ON.
(3) Erase DTCs and freeze frame data with the OBD II
scan tool (complying with SAE J1978) or the hand-
held tester. For the hand-held tester: 1) enter the
following menus: DIAGNOSIS ENHANCED OBD II
/ DTC INFO / CLEAR CODES; and 2) press YES.
For the OBD II scan tool, see its instruction manual.
(c) Clearing the DTCs without using the OBD ll scan tool or
the hand-held tester.
Remove the EFI or ECD No. 1 and ETCS fuses from the
engine room J/B for more than 60 seconds, or disconnect
the battery terminal for more than 60 seconds.
After disconnecting the battery terminal, perform the ºINI-
TIALIZEº procedure.

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
