Kia Rio: AGM Battery: Inspection
Battery Diagnostic Flow
Vehicle parasitic current inspection
1. |
Turn all the 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 electrical 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. |
Reconnect the suspected parasitic current draw circuit
fuse only and search for suspected unit by removing a component
connected with the circuit one by one until the parasitic draw
drops below limit value.
|
Limit value (after 10~20 min.)
: Below 50mA
