* Left rear side impact sensor terminal A
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.
* Left front side impact sensor terminal A and the SDM terminal 40.
* Right rear side impact sensor terminal A and the SDM terminal 47.
* Left rear side impact sensor terminal A and the SDM terminal 46.
瀚慖f greater than the specified range, test the circuit for an open/high resistance.
8. If all circuits test normal, replace the appropriate sensor.
9. Reconnect all SIR components. Ignition ON, with a scan tool clear and check for DTCs.
瀚慖f the DTC returns and is current, replace the SDM.
