INSPECTION
(1) Check upper frame and sensor brackets for deformities
or rust.
(2) Check sensor harness for binds, connectors for damage,
and terminals for deformities.
(3) Check for dents, cracks or deformation of the front impact
sensor.
Caution
If a dent, crack, deformation or rust is detected, re-
place with a new sensor.
(4) Remove the front impact sensor.
(5) Measure the resistance between terminals and check
whether it is within the standard value.
Standard value: 2,000 40
Caution
Always replace the sensor with a new one if the resis-
is not within the standard value.
(6) Check the continuity between the terminal and the bracket.
Digital multi-meter
If there is continuity, the insulation of the sensor is faulty.
Replace the sensor with a new one.
