Impact Sensor: Testing and Inspection
INSPECTIONWARNING: If a dent, crack, deformation or rust is detected, replace with a new sensor.
1. Check the front impact sensor for dents, cracks, deformation or rust.
WARNING: If the resistance value shows the short-circuit or the open-circuit, be sure to replace the front impact sensor with a new one.
2. Check the short-circuit or the open-circuit between the front impact sensor terminals.
When short-circuit: 2 ohm and less
When open-circuit: 2 mega ohm and over
3. Check for continuity between the terminal and the bracket. When there is continuity, it shows insufficient insulation of the sensor. Replace the sensor with a new one.
4. Check for deformation and rust on the radiator support panel.
