• The front impact sensors (FIS) are installed on the upper of the side panel in Front End Module (FEM). They are remote sensors that detect acceleration due to a collision at their mounting locations.
• The primary purpose of the Front Impact Sensor (FIS) is to provide an indication of a collition. The Front Impact Sensor(FIS) sends acceleration data to the SRSCM.

1.Disconnect the battery negative terminal.
• After disconnecting the cables, wait at least 3 minutes.
2.Remove the front impact sensor assembly (B) by loosening the bolt after disconnecting the connector (A).
Tightening torque :10.8 - 12.8 N.m (1.1 - 1.3 kgf.m, 8.0 - 9.4 lb-ft)

1.Install in the reverse of the removal.
2.After installing the FIS, confirm proper system operation.
• Switch ON the ignition. The SRS indicator light should turn on for about three-six seconds and then off.
