Component Inspection

■ Check IATS resistance 

1. IG "OFF". Disconnect IATS connector.
2. Measure resistance between signal and ground terminals of IATS connector after checking the temperature of IATS with GDS (Component Side)

   Specification: 

   Temp. (°C)	Resistance (kΩ)	Temp. (°C)	Resistance (kΩ)
   -40 (-40 °F)	38.88 ~ 50.77	20 (68 °F)	2.20 ~ 2.69
   -20 (-4 °F)	13.20 ~ 16.83	40 (104 °F)	1.02 ~ 1.27
   0 (32 °F)	5.12 ~ 6.12	60 (140 °F)	0.52 ~ 0.65
   10 (50 °F)	3.31 ~ 4.10	80 (176 °F)	0.28 ~ 0.35

3. 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.
