Circuit/System Testing
WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the appropriate connector at the F101 Instrument Panel Airbag:
- DTC B0010 = X1
- DTC B0011 = X2
- Test for greater than 25 Ω between control circuit terminal 1 and control circuit terminal 2.
- If 25 Ω or less
- Verify the appropriate circuits are not shorted together:
- DTC B0010 = Circuit 3025 and circuit 3024
- DTC B0011 = Circuit 3027 and circuit 3026
- If a short between the circuit is found, repair the fault on the circuit.
- Go to next step: If a short between the circuits is not found
- Replace the K36 Restraints Control Module.
NOTE:Some connectors may be equipped with shorting bars as a safety component to prevent accidental inflator deployment. When testing on a connector with shorting bars, the shorting bars must be disabled to ensure accurate test results. Insert an appropriate pick from EL-38125-580 and depress the shorting bars above the appropriate terminals. This will lift the shorting bar from the terminal and allow accurate test results. Take care not to damage the connector, shorting bar, or terminal when depressing the shorting bar.
- Go to next step: If greater than 25 Ω
- Ignition ON.
- Test for less than 11 V between the control circuit terminals listed below and ground:
- Control circuit terminal 1
- Control circuit terminal 2
- If 11 V or greater
- Test the following circuits for a short to voltage:
- DTC B0010 = Circuit 3025 and circuit 3024
- DTC B0011 = Circuit 3027 and circuit 3026
- If a short to voltage is found, repair the fault on the circuit.
- Go to next step: If a short to voltage is not found
- Replace the K36 Restraints Control Module.
- Go to next step: If less than 11 V
- Ignition OFF.
- Test for greater than 25 Ω between the control circuit terminals listed below and ground:
- Control circuit terminal 1
- Control circuit terminal 2
- If 25 Ω or less
- Test the following circuits for a short to ground:
- DTC B0010 = Circuit 3025 and circuit 3024
- DTC B0011 = Circuit 3027 and circuit 3026
- If a short to ground is found, repair the fault on the circuit.
- Go to next step: If a short to ground is not found
- Replace the K36 Restraints Control Module.
- Go to next step: If greater than 25 Ω
- Ignition OFF, install a 3 A fused jumper wire between control circuit terminal 1 and control circuit terminal 2, ignition ON.
- Verify the scan tool Deployment Loop Resistance parameter is less than 2 Ω.
- If 2 Ω or greater
- Test the following circuits for an open/high resistance:
- DTC B0010 = Circuit 3025 and circuit 3024
- DTC B0011 = Circuit 3027 and circuit 3026
- If an open/high resistance is found, repair the fault on the circuit.
- Go to next step: If an open/high resistance is not found
- Replace the K36 Restraints Control Module.
- Go to next step: If less than 2 Ω
- Ignition OFF, connect the harness connector at the F101 Instrument Panel Airbag and press in the CPA (if equipped) until an audible and/or tactile click is heard.
- Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
- Verify DTC B0010 or B0011 is not set.
- If DTC B0010 or B0011 is set
Replace the F101 Instrument Panel Airbag.
- Go to next step: If DTC B0010 or B0011 is not set
- If DTC B0010 or B0011 is set
- A fault is not currently present and may be an intermittent condition.
