Kia Stinger (CK) 2018-2023 Service Manual: Driver Airbag (DAB) Module and Clock Spring

Description and operation Description Driver Airbag (DAB) is installed in the steering wheel and electrically connected to SRSCM via the clock spring. It protects the driver by deploying the airbag when frontal crash occurs. The SRSCM determines deployment of the Driver Airbag (DAB).    Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester.

Kia Stinger (CK) 2018-2023 Service Manual: Knee Airbag (KAB) Module

Description and operation Description Installed inside the crash pad, the knee airbag (KAB) protects the driver in the event of a frontal crash. The SRSCM determines if and when to deploy the KAB.    Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using a specified tester.
