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 (Component Side)
Temp. (℃) | Resistance (kΩ) | Temp. (℃) | 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 ?
 | ▶ Go to "Verification of Vehicle Repair" procedure. |
 | ▶ 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. |
