瀚慖f greater than the specified range, test the circuit for a short to voltage.

5. Test for infinite resistance between the signal circuit and ground.

* Right front end sensor terminal 1

* Left front end sensor terminal 1

* Right front side impact sensor terminal B

* Left front side impact sensor terminal B

* Right rear side impact sensor terminal B

* Left rear side impact sensor terminal B

瀚慖f less than the specified value, test the circuit for a short to ground.

6. Test for less than 1 ohm between the following signal circuit terminals.

* Right front end sensor terminal 1 and SDM terminal 37.

* Left front end sensor terminal 1 and SDM terminal 36.

* Right front side impact sensor terminal B and the SDM terminal 43.

* Left front side impact sensor terminal B and the SDM terminal 42.

* Right rear side impact sensor terminal B and the SDM terminal 45.

* Left rear side impact sensor terminal B and the SDM terminal 44.

瀚慖f greater than the specified range, test the circuit for an open/high resistance.

7. Test for less then 1 ohm between the following front end sensor low reference circuit terminals.

* Right front end sensor terminal 2 and SDM terminal 39.

* Left front end sensor terminal 2 and SDM terminal 38.

* Right front side impact sensor terminal A and the SDM terminal 41.
