Component Inspection

■ Check IATS resistance 

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

   Specification: 

   Temp. (°C)	Resistance (kΩ)	Temp. (°C)	Resistance (kΩ)
   -40	40.93 ~ 48.35	20	2.31 ~ 2.57
   -20	13.89 ~ 16.03	40	1.08 ~ 1.21
   0	5.38 ~ 6.09	60	0.54 ~ 0.66
   10	3.48 ~ 3.90	80	0.29 ~ 0.34

3. Is the measured resistance within 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.
