Impact Sensor: Testing and Inspection

WARNING:
1. Never repair or disassemble the front impact sensor. If faulty, replace it.
2. Handle the front impact sensors very carefully, taking care not to drop them or otherwise subject them to impact. It a sensor is dented, cracked, deformed or rusted, replace it with a new one.
3. Replace the sensors with new ones after the air bag has deployed.

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 it the resistance is not within the standard value.







2. Measure the resistance between the terminals and check whether ii is within the standard value.
Standard value: 2,000 ± 40 ohms

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.
