Component Inspection
- Check OCV resistance
- IG "OFF" and disconnect OCV connector.
- Measure resistance between power and signal terminals of OCV. (Component Side)
Specification: 6.7 ~ 7.7 Ω
- 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.
- OCV Actuation Test
- Connect scantool and IG "ON".
- Select "OIL CONTROL VALVE" on the Actuation Test.
- Activates "OIL CONTROL VALVE" by pressing "START" button.
(Should hear a faint click from Oil Control solenoid Valve)
- Repeat this procedure 4 or 5 times to ensure oil control solenoid valve reliability.
- 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.NOTE: 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.
- 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.
