• The front impact sensor is installed on the headlamp support panel upper in the engine room, and the analogue G-sensor is housed in the front impact sensor.
  • The front impact sensor transmits the coded acceleration data to SRS-ECU. Based on the data, SRS-ECU determines the deployment stage of the front air bag, then energises appropriate squib.
  • SRS-ECU performs the diagnostics of the front impact sensor internal components. If a malfunction occurs, it sets the diagnosis code.
