Component Inspection
- Check IATS resistance
- IG "OFF" and disconnect IATS connector.
- Measure resistance between signal and ground terminals of IATS connector after checking out the temperature of IATS with GDS (Component Side)RESISTANCE SPECIFICATION
Temp. (°C) Resistance (kΩ) -40 95.95 ~ 105.78 -20 27.4 ~ 29.77 0 9.08 ~ 9.72 10 5.49 ~ 5.83 20 3.42 ~ 3.61 40 1.43 ~ 1.5 60 0.66 ~ 0.69 80 0.33 ~ 0.34 - Is the measured resistance within specification?
YES
- 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.
