Front Impact Sensors: Inspection

WARNING: If a dent, crack, deformation or rust is detected, replace with a new sensor.

Check the front impact sensor for dents, cracks, deformation or rust.
WARNING: Always replace the sensor with a new one of the resistance is not within the standard value.
Measure the resistance between the terminals and check whether it is within the standard value.
Standard value: 820 +/- 82 Ω

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.
