Is each measured resistance infinity? 		 Go to Step 4. For DTC B1087: "WHT/RED" circuit or "LT GRN/BLK" circuit shorted to ground. For DTC B1087: "WHT/GRN" circuit or "LT GRN" circuit shorted to ground.
4  Check side-sensor referring to SIDE-SENSOR INSPECTION:ADVANCED AIR BAG .
Is it in good condition? 		 Substitute a known-good SDM and recheck. Replace side-sensor referring to SIDE-SENSOR REMOVAL AND INSTALLATION:ADVANCED AIR BAG . If DTC still exists, substitute a known-good SDM and recheck.
