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 ?






NOTE: There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM. Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
