Component Inspection

Check IATS resistance

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

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.
