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 | 95.95 ~ 105.78 | 20 | 3.42 ~ 3.61 |
-20 | 27.4 ~ 29.77 | 40 | 1.43 ~ 1.5 |
0 | 9.08 ~ 9.72 | 60 | 0.66 ~ 0.69 |
10 | 5.49 ~ 5.83 | 80 | 0.33 ~ 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. |
