Fig.1) GDS Multimeter voltage check

Is the measured voltage within specifications?

	▶ Substitute with a known-good Sample of SPAS Switch and check for proper operation. If problem is corrected, replace SPAS Switch and then go to "Verification of Vehicle Repair" procedure.
	▶ Check the open or short of the SPAS Switch Indicator circuit. And then go to "Verification of vehicle Repair" procedure.
