Component Inspection

Component Inspection

1. Check IATS
(1) IG "OFF" and disconnect IATS connector.
(2) Measure resistance between terminals 4 and 5 of IATS connector. (Component side)
Specification :









(3) Is the measured resistance within specification ?





2. Check PCM
(1) IG "OFF" and connect scantool.
(2) Disconnect IATS connector and connect probe to terminal 4 of IATS harness connector.
(3) IG "ON" and ENG "OFF" and simulation Function on scantool.
(4) Simulate voltage at terminal 4 of IATS harness connector.




(5) Does the signal value of IAT sensor change according to simulation voltage ?
