Component Inspection

1. Check CMPS, CKPS
(1) Key "OFF". (Don't disconnect sensors.)
(2) Select "vehicle scopemeter" in the menu, and connect channel A of scantool with terminal 2 of CKPS harness connector.
(3) Connect Channel B of scantool with terminal 1 or 2 of CMPS harness connector.
(4) Engine start. And check the signal waveforms.
A. Specification :




(5) Is the measured signal waveforms of CKPS/CMPS normal?
YES
1) Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "Verification of Vehicle Repair" procedure.

CAUTION:
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

NO
1) Go to "Check OCV" procedure.
2. Check OCV
(1) Connect scantool to Data Link Connector (DLC).
(2) Key "ON".
(3) Perform "Actuation Test" for OCV.




(4) Does the OCV work normally (Check clicking sound) ?
YES
1) Go to "Check timing mark" procedure.
NO
1) Substitute with a known-good OCV and check for proper operation. If the problem is corrected, replace OCV and then go to "Verification of Vehicle Repair" procedure.
3. Check timing mark
(1) Key "OFF".
(2) Check timing mark.
A. Specification :




(3) Is timing mark normal?
YES
1) Substitute with a known-good CVVT and check for proper operation. If the problem is corrected, replace CVVT and then go to "Verification of Vehicle Repair" procedure.
NO
1) Reset timing mark, and go to "Verification of Vehicle Repair" procedure.
