Circuit/System Description

If a malfunction is detected, a DTC will be stored in non-volatile memory. During a side or frontal crash 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 LH front side module. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. A shorting bar used within the LH front side module connector which will short together both RF side module high and low circuits 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 LH front side module high and/or low circuit is short to voltage.

B0014 02

The LH front side module high and/or low circuit is short to ground.

B0014 04

The LH front side module high and/or low circuit is open.

B0014 0D

The LH front side module deployment loop resistance is more than 3.45 ohms.

B0014 0E

The LH front side module deployment loop resistance is less than 1.77 ohms.

Circuit/System Testing

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

•	The I/P module

•	The SDM module

•	The I/P wiring harness connector

•	The SDM wiring harness connector

1. Ignition OFF, disconnect LH front side module in-line connector.
2. Disconnect the SDM connector. Refer to SDM replacement in Repair Instructions for connector location.
3. Test the high and low circuits between the SDM and LH front side module for a short to voltage, short to ground, short between circuits or open/high resistance. Verify that a short to voltage, short to ground, short between circuits or open/high resistance does not exist.

⇒	If any of the above conditions are found make the appropriate repair.

4. If all circuits test normal then replace the SDM.
5. Ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B0014 is set current.

⇒	Replace the LH front side module.
