Component Inspection
- Check resistance of IATS
- IG "OFF" and disconnect IATS connector.
- Measure resistance between signal and ground terminals of IATS connector after checking out the temperature of IATS with scantool
- Specification :

YES
- Substitute with a known - good PCM and check for proper operation.
If the problem is corrected, replace PCM and 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.
