Kia Optima: Inspection
Battery Diagnostic Flow
Vehicle parasitic current inspection
|
1. |
Turn the all electric devices OFF, and then turn
the ignition switch OFF. |
|
2. |
Close all doors except the engine hood, and then
lock all doors.
|
(1) |
Disconnect the hood switch connector. |
|
(3) |
Close the doors or remove the door switches. |
|
|
3. |
Wait a few minutes until the vehicle’s electrical
systems go to sleep mode.
|
For an accurate measurement of a vehicle
parasitic current, all electriacl systems should go to sleep
mode. (It takes at least one hour or at most one day.) However,
an approximate vehicle parasitic current can be measured after
10~20 minutes. |
|
|
4. |
Connect an ammeter in series between the battery
(-) terminal and the ground cable, and then disconnect the clamp from
the battery (-) terminal slowly.
|
Be careful that the lead wires of an ammeter
do not come off from the battery (-) terminal and the ground
cable to prevent the battery from being reset. In case the battery
is reset, connect the battery cable again, and then start the
engine or turn the ignition switch ON for more than 10 sec.
Repeat the procedure from No. 1. To prevent the battery from being reset during
the inspection,
| 1) |
Connect a jump cable between the
battery (-) terminal and the ground cable. |
| 2) |
Disconnect the ground cable from
the battery (-) terminal.
|
| 3) |
Connect an ammeter between the battery
(-) terminal and the ground cable. |
| 4) |
After disconnecting the jump cable,
read the current value of the ammeter.
|
|
|
|
5. |
Read the current value of the ammeter.
| A. |
If the parasitic current is over the limit
value, search for abnormal circuit by removing a fuse one by
one and checking the parasitic current.
|
| B. |
Check the parasitic current again, and search
for suspected unit by removing a unit connected with the abnormal
circuit one by one.
|
Limit value (after
10~20 min.) : Below 50mA
|
|
1.
Disconnect the terminals from the battery.
Tightening torque
:(+) terminal (A) : 7.8 ~ 9.8N.m (0.8 ~ 1.0kgf.m,
5.8 ~ 7.2lb-ft)
(-) terminal (B) : 4.0 ...
1.
Make sure the ignition switch and all accessories
are in the OFF position.
2.
Disconnect the battery cables (negative first).
