For 1990-2009 cars

### Circuit Description

When the ignition is turned ON, the inflatable restraint sensing and diagnostic (SDM) performs continuous diagnostic tests to check for proper circuit continuity and for shorts to ground or voltage. During one portion of these tests, the SDM checks to ensure that it is properly configured for this vehicle. If a malfunction is detected, the SDM will store a diagnostic trouble code (DTC).

### Conditions for Running the DTC

Ignition 1 voltage is within the normal operating voltage range.

### Conditions for Setting the DTC

The SDM is not properly configured for this vehicle.

### Action Taken When the DTC Sets

The SDM turns the AIR BAG indicator ON.

### Conditions for Clearing the DTC

You can use the scan tool to properly configure the SDM. Once the SDM is properly configured, the DTC will clear.

### Diagnostic Aids

DTC 52 indicates that the SDM is not configured for use in this vehicle.
