Component Inspection

Component Inspection

1. Check OCV
(1) IG "OFF" and disconnect OCV connector.
(2) Measure resistance between terminal 1 and 2 of OCV. (Component Side)
A. Specification :









(3) Is the measured resistance within specification?
YES
- Go to "OCV Actuation Test" as follows.
NO
- Substitute with a known-good OCV and check for proper operation. If the problem is corrected, replace OCV and go to "Verification of Vehicle Repair" procedure.
2. OCV Actuation Test
(1) Connect scantool and IG "ON".
(2) Select "OCV" on the Actuation Test.
(3) Activate "OCV" by pressing "STRT (F1)" key.
(should hear a faint click from Oil Control solenoid Valve)
(4) Repeat this procedure 4 or 5 times to ensure reliability




(5) Does OCV generate click sound during actuation test?
YES
- Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and 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 ECM.
Before or after testing ECM on the vehicle, use this function to reuse the ECM on the others

NO
- Substitute with a known-good OCV and check for proper operation. If the problem is corrected, replace OCV and go to "Verification of Vehicle Repair" procedure.
