Kia Sorento: General Safety Information and Caution

Kia Sorento (MQ4, 2021-2026) Service Manual / Restraint / General Safety Information and Caution

Precautions when repairing the airbag system

When repairing the SRS, pay attention to the following items.

If the items below are not observed, there is a possibility of serious injury due to unexpected airbag deployment, and the airbag may not operate.

1.	After disconnecting the ( + ) connector of the auxiliary 12 V battery in the IG OFF state, wait at least 3 minutes and 30 seconds before starting related work. (Backup power is valid for about 150 ms)

2.	Failure symptoms of the airbag system are difficult to identify. When troubleshooting, the DTC provides the most important information.

3.	When repairing an airbag system fault, always inspect the DTC before removing the battery.

Do not measure the resistance of the airbag squib connector. (It is very dangerous because the airbag can be activated.)

Squib : It is an ignition device installed in the inflator of the electric airbag.

5.	Be careful not to damage the airbag module by oil, grease, cleaner and water.

6.	Do not use airbag components from other vehicles.

7.	When replacing components, replace them with new ones.

8.	Do not disassemble or repair to reuse for all airbag system components.

9.	When installing the airbag system, be careful not to impact around the airbag control unit and impact sensor. The airbag may be suddenly deployed, which may cause damage and injury.

10.	If the airbag module is dropped or other defects such as cracks, dents on the case, the bracket and the connector are occurred, replace them with new ones.

11.

After completing the airbag system repair, check the warning lamp and delete the DTC.

The operation of the airbag warning lamp may be blocked by other circuit faults. Therefore, when the airbag warning lamp turns on, the DTC is deleted by using the KDS.

12.	After completing the repair and inspection of the SRS, be sure to initialize the system. (Keep IG ON for more than 7 seconds → Keep IG OFF for more than 3 minutes and 30 seconds → Keep IG ON for more than 7 seconds)

Airbag Handling and Storage

1.	Do not disassemble the airbag.

2.	The deployed airbags cannot be reused.

Be sure to observe the following precautions when storing the airbag.

•	Store the airbag module with the top side of the cover facing upward.

•	The double locking connector lever must be locked, and positioned so that the connector is not damaged.

•	Be careful not to damage the airbag module by oil, grease, cleaner and water.

•	Store in a place where the ambient temperature is below 60°C (140°F), humidity is not high, and there is no electrical noise.

•	Follow the disposal procedure for the damaged airbags. (Refer to Airbag Module - "The Airbag Module Disposal Procedure")

Wiring Precautions

Observe the precautions described below.

•	Never reconnect or repair the damaged airbag wiring. If the airbag wiring is damaged, replace the harness.

•	Make sure the wiring is not interfered with other components.

•	Make sure that there are no foreign substances on the connector surface of the airbag. Poor grounding can cause problems that are difficult to diagnose.

Precautions for Inspections

When using the tester, insert the tester probe into the connector wire side. Do not insert the tester probe into the terminal side of the connector.

Use a U-shaped probe and do not forcefully insert the probe.

Airbag Connector Precautions

1.	Disconnect the connector To disconnect the connector, remove the connector by holding the connector and pulling the spring loaded sleeve (A) and slider (B) from the opposite side. Be careful to pull the sleeve, not the connector.

Connect the connector

Hold both connectors and push firmly until the protrusion (C) of the connector on the sleeve side clicks into place.
