The seat belt pretensioner deployment loop consists of a seat belt pretensioner, the seat belt pretensioner - high and seat belt pretensioner - low circuits. A shorting bar is used in the seat belt pretensioner connector which will short together the seat belt pretensioner - high and seat belt pretensioner - low circuits when the connector is disconnected, this will help to prevent unwanted deployment of the pretensioner 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.
Ignition 1 Voltage is within the normal operating voltage range.
The SDM detects a short to ground in the seat belt pretensioner - RF deployment loop.
The SDM commands the AIR BAG indicator to flash.
The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
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:
• | A short to ground in the seat belt pretensioner - right - high or the seat belt pretensioner - right - low circuits |
• | A malfunctioning seat belt pretensioner |
• | An internal SDM malfunction |
If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
The numbers below refer to the step numbers on the diagnostic table.
Tests to see if the malfunction is caused by the seat belt pretensioner.
Tests for a short to ground in the Seat Belt Pretensioner - High and Seat Belt Pretensioner - Low circuits.
