Component Inspection

Component Inspection

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









(3) Is the measured resistance within specification ?





2. Check signal waveform of CKPS
(1) IG "OFF" and connect scantool.
(2) ENG "ON" and Measure signal waveform at terminal 1 or 2 of CKPS.

Reference signal waveform :




(3) Is the measured signal waveform normal ?






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
