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: 1 Ohm and less
When open-circuit: 1 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.
