WARNING: 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: Always replace the sensor with a new one of the resistance is not within the standard value.

2. Measure the resistance between the terminals and check whether it is within the standard value.

Standard value: 820 ± 82 ohm

3. Check the fender shield panel for deformation or rust.




4. Check the continuity between the terminal and bracket. If there is a continuity, the insulation is damaged, Replace the sensor with a new one.
