Circuit Description

The inflatable restraint side impact module deployment loop consists of an inflatable restraint side impact module, the side impact module - high and side impact module - low circuits. A shorting bar is used in the inflatable restraint side impact module connector which will short together the side impact module - high and side impact module - low circuits when the connector is disconnected, this will help to prevent unwanted deployment of the inflator module during servicing. When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored.

Conditions for Running the DTC

Ignition 1 Voltage is within the normal operating voltage range.

Conditions for Setting the DTC

The SDM detects a high resistance condition in the side impact module - RF deployment loop.

Action Taken When the DTC Sets

The SDM commands the AIR BAG indicator to flash.

Conditions for Clearing the DTC

The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.

Diagnostic Aids

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 the reappearance of the malfunction.

The following are possible causes of the malfunction:

    • An open or high resistance in the side impact module - right - high or the side impact module - right - low circuits.
    • A malfunctioning inflatable restraint side impact module.
    • An internal SDM malfunction.

If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.

Test Description

The numbers below refer to the step numbers on the diagnostic table.

  1. Tests to see if the malfunction is caused by the inflatable restraint side impact module.

    2.

  2. Tests for an open or high resistance in the Side Impact Module High and Side Impact Module Low circuits.

  1. Turn OFF the ignition.
  2. Disconnect the side impact module - RF connector.
  3. Inspect both the component and harness sides of the connector for the following conditions:
    4. • Corrosion
    • Damaged terminals
    • Poor contact/terminal tension

Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.

Does the connector exhibit any of the above conditions?

Go to Step 4

Go to Step 5

  1. If the component side of the side impact module connector is damaged, the side impact module must be replaced. Refer to Inflatable Restraint Side Impact Module Replacement - Right Side .
  2. If the harness side of the side impact module connector is damaged, replace the harness side of the connector. Refer to Connector Repairs in Wiring Systems.

Did you complete the replacement?

  1. Connect a 3 amp fused jumper wire between the side impact module - high and the side impact module - low circuits on the harness side of the side impact module connector.
  2. Turn ON the ignition, with the engine OFF.
  3. Use the scan tool in order to Clear the DTCs.
  4. With the scan tool, request the SIR DTC display.

Does the scan tool indicate that DTC B0111 is current?

  1. Turn OFF the ignition.
  2. Disconnect the SDM connector.
  3. Inspect the SDM connector for the following conditions:
    4. • Corrosion
    • Damaged terminals
    • Poor contact/terminal tension

Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?
