•

Do not drop or subject the front impact sensor to impact or vibration. If denting, cracking, 
deformation, or rust are discovered in the front impact sensor, replace it with a new front 
impact sensor. Discard the old one.

•

After deployment of an air bag, replace the front impact sensor with a new one.

INSPECTION

M1524001600222

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 if 
the resistance shows a short or open circuit.

2. Measure the resistance between terminals and 

check whether it is within the standard value.

Standard value: 820 

±

 82 

Ω

3. Check the continuity between the terminal and 

bracket. If there is a continuity, the insulation is 
malfunctioned, and replace the sensor with a new 
one.

4. Check the head lamp support pane for
