Circuit Description
When the ignition switch is turned to ON, the sensing and diagnostic module (SDM) will perform a turn-on test to diagnose critical malfunctions within the SDM itself.
These test ignition and deployment loop voltages are measured to ensure that they are within their normal voltage ranges. The SDM monitors the voltages at the driver low and the passenger low to detect shorts to ground or voltage in the deploy loops.
Conditions for Setting the DTC
| • | The side air bag sensor wiring of the driver high is shorted to battery wiring. |
| • | The side air bag sensor wiring of the driver low is shorted to battery wiring. |

Has the SDM discharged? | -- | Go to Step 2 | -- |
2 | Visually inspect any damage for the driver side air bag sensor wiring and the connector. Are the driver side air bag sensor wiring and connector OK? | -- | Go to Step 4 | Go to Step 3 |
3 | Connect the connector or repair the damage. Is the action complete? | -- | -- | |
4 | Measure the resistance between the SDM and the high, low terminal of the driver side air bag sensor and the battery. Is the resistance equal to the specified value? | 10 K ohms | Go to Step 5 | Go to Step 7 |

Is the DTC removed? | -- | Go to Step 6 | |
6 | Replace the driver side air bag sensor. Refer to Inflatable Restraint Side Impact Sensor Replacement . Is the replacement complete? | -- | -- | |
7 | Replace the air bag wiring. Is the replacement complete? | -- | -- | |
