Component Inspection

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

      SPECIFICATION: 

      RESISTANCE SPECIFICATION

      Resistance (Ω) 6.7 ~ 7.7 Ω at 20°C (68°F)

    3. Is the measured resistance within specification?

      YES 

      • Go to " 2OCV 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 PCM and check for proper operation. If the problem is corrected, replace PCM 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 PCM.
      Before or after testing PCM on the vehicle, use this function to reuse the PCM 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.
