Circuit/System Description 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. Conditions for Running the DTC Ignition On Ignition voltage is between 9–16 V Conditions for Setting the DTC B0010 11 Circuit 3025 or circuit 3024 is shorted to ground for 2 s. B0011 11 Circuit 3027 or circuit 3026 is shorted to ground for 2 s. B0010 12 Circuit 3025 or circuit 3024 is shorted to voltage for 2 s. B0011 12 Circuit 3027 or circuit 3026 is shorted to voltage for 2 s. B0010 13 Circuit 3025 or circuit 3024 is open for 2 s. B0011 13 Circuit 3027 or circuit 3026 is open for 2 s. B0010 1A Circuit 3025 or circuit 3024 resistance is less than 1.7 Ω for 2 s. B0011 1A Circuit 3027 or circuit 3026 resistance is less than 1.7 Ω for 2 s. B0010 1B Circuit 3025 or circuit 3024 resistance is greater than 4.4 Ω for 2 s. B0011 1B Circuit 3027 or circuit 3026 resistance is greater than 4.4 Ω for 2 s. Action Taken When the DTC Sets Airbag Indicator ON. Conditions for Clearing the DTC A current DTC will clear when the diagnostic runs and passes. A history DTC will clear after 100 consecutive malfunction-free ignition cycles. Diagnostic Aid

Note

The following diagnostic aids apply for both current and history DTCs. Refer to SIR Disabling and Enabling. Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with a reappearance of the malfunction. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections. An incorrectly seated connector can cause an open/high resistance condition. Check the circuit terminals for fretting or incorrectly seated connector if a DTC with symptom byte 1B is set.

Note

The condition may be intermittent and require driving the vehicle, then reviewing the snapshot to verify resistance parameters do not drop out or spike. Refer to Testing for Intermittent Conditions and Poor Connections

1. Verify the appropriate scan tool Deployment Loop Resistance parameters stay consistently between 2.1 and 4.0 Ω for the F101 Instrument Panel Airbag. ⇒ If less than 2.1 or greater than 4.0 Ω Refer to Circuit/System Testing. ⇓ If within 2.1 and 4.0 Ω without any spikes or dropouts
2. A fault is not currently present and may be an intermittent condition. Circuit/System Testing

Note

Refer to SIR Service Precautions. Refer to SIR Disabling and Enabling. Always test the harness side when circuit testing deployment loops. Never test a component on a deployment loop with the DVOM. Inspect all terminals for damage or corrosion when disconnecting connectors. Damage or corrosion in the following requires repair or replacement of the affected component/connector. Instrument Panel Airbag Restraints Control Module Airbag wiring harness connector Restraints Control Module wiring harness connector The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click.
