Circuit/System Description

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The F101 Instrument Panel Airbag is a dual-stage inflator located in the Instrument Panel. The F101 Instrument Panel Airbag contains a housing, inflatable airbag, an initiating device, a canister of gas generating material and, in some cases, stored compressed gas. The F101 Instrument Panel Airbag uses two discrete deployment loops to supply current and deploy each state of the airbag. Each deployment loop has a high control circuit that will supply voltage to deploy the airbag and a low control circuit that will supply ground to deploy the airbag. Stage 1 uses circuit 3025 as a high control and circuit 3024 as a low control. Stage 2 uses circuit 3027 as a high control and circuit 3026 as a low control.

Based on inputs from the impact sensors, the K36 Restraints Control Module will command deployment of Stage 1 or Stage 2 of the F101 Instrument Panel Airbag depending on crash specifics. To deploy the F101 Instrument Panel Airbag, the K36 Restraints Control Module will simultaneously apply voltage to the high control circuit and ground to the low control circuit.
