Kia Sorento: Battery Parasitic Current Check

1
Turn off all electrical devices, then turn the ignition switch OFF.
2
Close all doors except the hood, then lock all doors.
1. Disconnect the hood switch connector.
2. Close the liftgate.
3. Close the doors or remove the door switches.
3
Wait several minutes until the vehicle electrical systems enter sleep mode.
NOTE
- To accurately measure the vehicle's parasitic current, all electrical systems must enter sleep mode. (This takes at least one hour, or up to one day.) However, an approximate parasitic current can be measured after 10~20 minutes.
4
Connect the ammeter in series between the battery negative (-) terminal and the ground cable, then slowly disconnect the ground cable from the battery negative (-) terminal.
NOTE
- Be careful that the ammeter lead wires do not come off the battery (-) terminal and ground cable, to prevent the battery from being reset. If the battery is reset, reconnect the battery cable, then start the engine or turn the ignition switch ON for more than 10 seconds. Repeat the procedure from No. 1. To avoid resetting the battery during inspection,
1. Connect the jumper cable to the negative (-) battery terminal and the ground cable.
2. Disconnect the ground cable from the battery (-) terminal.
3. Connect the ammeter to the negative (-) battery terminal and the ground cable.
4. After disconnecting the jumper cable, read the current value on the ammeter.

Read the ammeter current value.

A.	If the parasitic current exceeds the limit value, search for the abnormal circuit by removing the fuses one by one and checking the parasitic current.

B.	Reconnect the suspected parasitic current consuming circuit fuse only, and find the suspect unit by removing the fuses with the circuit one by one until the parasitic draw drops below the limit value.
