Component Inspection

■ Check IATS performance 

1. Ignition "OFF".
2. Disconnect IATS connector.
3. Measure resistance between Pin No. 3 (Signal) terminal and Pin No. 4 (Ground) terminal of the IATS. (component side)

   Specification: Refer to Table 

   Temperature [°C (°F)]	Resistance [kΩ]	Temperature [°C (°F)]	Resistance [kΩ]
   -40 (-40)	40.93 to 48.35	40 (104)	1.08 to 1.21
   -20 (-4)	13.89 to 16.03	50 (122)	0.76 to 0.85
   0 (32)	5.38 to 6.09	60 (140)	0.54 to 0.62
   10 (50)	3.48 to 3.9	80 (176)	0.29 to 0.34
   20 (68)	2.31 to 2.57

4. Is the measured value within specification?

   YES 

   • Go to "Verification of Vehicle Repair " procedure.

   NO 

   • Carefully re-do this troubleshooting guide steps.
   • If no problems were found with the circuits or connectors, replace the IATS and go to "Verification of Vehicle Repair " procedure.
