Impact Sensor: Service and Repair

Inspection

1. Check upper frame and sensor brackets for deformation or rust.

2. Check sensor harness for binds, connectors for damage, and terminals for deformation.

3. Check for dents, cracks, deformation or rust of the front impact sensor.

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

4. Measure the resistance between terminals and check whether it is within the standard value.Standard value: 2,000 +/- 20 ohms.

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

INSTALLATION SERVICE POINT

PRE-INSTALLATION INSPECTION

To mount the new front impact sensor, visually check it and measure the resistance between the terminals. (Refer to the previous item "INSPECTION")





FRONT IMPACT SENSOR INSTALLATION

1. Securely connect the connector.

2. Set the front impact sensor towards the front of the vehicle as shown by the arrow in the illustration, and install it securely.

Caution:The SRS may not activate properly if a front impact sensor is not installed properly, which could result in the SRS system not operating properly during a collision.


POST-INSTALLATION INSPECTION

Reconnect the negative battery terminal. Turn the ignition key to the "ON" position. Does the "SRS" warning light illuminate for about 7 seconds, turn OFF and then remain OFF for at least 45 seconds? If yes, SRS system is functioning properly. If no, consult SRS Warning Light Inspection. Testing and Inspection
