- An open or a high resistance in the seat belt pretensioner LF high or low circuits
- A short to ground or a short to voltage in the seat belt pretensioner LF high or low circuits
- The seat belt pretensioner LF connector

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. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
