Circuit/System Description

During a side impact event of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the side impact modules. The SDM performs continuous diagnostic tests on the deployment loops to check for correct circuit continuity and for shorts to ground or voltage. There is a shorting bar used within the side impact modules coil connector which will short together the side impact module high circuit and side impact module low circuit when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

B0014 01

The side impact module high and/or low control circuit is shorted to voltage for 2 seconds.

B0014 02

The side impact module high and/or low control circuit is shorted to ground for 2 seconds.

B0014 08

The side impact module high and/or low signal control circuit is invalid during SDM initialization.

B0014 0D

The side impact module deployment loop resistance is more than 5.5 ohms for 2 seconds.

B0014 0E

The side impact module deployment loop resistance is less than 1.1 ohms for 2 seconds.

Circuit/System Testing

Important: Refer to SIR Service Precautions.

When removing the connectors, inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:

•	Side impact module- driver

•	SDM module

•	Side impact module wiring harness connector

•	SDM wiring harness connector

Important: 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. The CPA isolates the shoring-bars within the connector allowing the deployment circuit to operate properly.

1. Ignition OFF, disconnect the harness connector at the driver inflatable restraint side impact module.
2. Ignition ON, verify that the scan tool Driver Side Airbag Squib Circuit Resistance parameter is greater than 5.4 ohms at the control circuits.

⇒	If less than the specified range, test the control circuits for a short to ground. If the circuits test normal, replace the SDM.

3. Connect a fused jumper wire in between the side impact module terminal 1 X1 and terminal 2 X1.
4. Ignition ON, verify that the scan tool Driver Side Airbag Squib Circuit Resistance parameter is less than 1.2 ohms at the control circuits.

⇒	If greater than the specified range, test the control circuits for a short to voltage or an open/high resistance. If the circuits test normal, replace the SDM.

5. If all circuits test normal, replace the driver inflatable restraint side impact module.
