Description
The Knee Airbag (KAB) is installed inside the crash pad lower panel and 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. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.
