When removing connectors, inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of
the affected component/connector:
* Front end sensor
* SDM module
* Front end sensor wiring harness connector
* SDM wiring harness connector
1. Ignition OFF, disconnect the harness connector at the appropriate sensor.
2. Disconnect the harness connector at the SDM.
3. Ignition ON, test for less than 1 volt between the following 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 greater than the specified range, test the circuit for a short to voltage.
4. Ignition ON, test for less than 1 volt between the low reference circuit and ground.
* Right front end sensor terminal 2
* Left front end sensor terminal 2
* Right front side impact sensor terminal A
* Left front side impact sensor terminal A
* Right rear side impact sensor terminal A
