Component Inspection

Check IATS resistance

IG "OFF" and disconnect IATS connector.

Measure resistance between signal and ground terminals of IATS connector after checking out the temperature of IATS with GDS (Component Side)

Is the measured resistance within specification?
YES

Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NO

Substitute with a known - good IATS and check for proper operation. If the problem is corrected, replace IATS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
