Component Inspection

1. Check resistance of OTS
(1) IG "ON" & ENG "OFF"
(2) Monitor Oil Temperature parameter on the scantool
(3) IG "OFF" & ENG "OFF"
(4) Disconnect OTS connector.
(5) Measure resistance between terminal 1 and 2 of OTS connector (Component Side)
Specification









(6) Is the measured resistance within specification?





2. Check PCM
(1) Ignition "OFF" and Connect Scantool
(2) Ignition"ON " & Engine "OFF"
(3) Select simulation function on scantool.
(4) Simulate voltage at terminal "1" of OTS signal harness connector.




(5) Does the OTS signal value changes according to simulation voltage?






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