Component Inspection

  1. Check ETS motor
    1. Ignition "OFF"
    2. Disconnect ETS motor connector
    3. Measure resistance between terminals 1 and 2 of the ETS motor harness connector.
    4. Measure resistance between terminals 1 and 3 of the ETS motor harness connector.
    5. Measure resistance between terminals 2 and 3 of the ETS motor harness connector.

      Specification:

      Approx. 2.5Ω (1 --> 2)

      Approx. 2.5Ω (1 --> 3)

      Approx. 2.5Ω (2 --> 3)

      NOTE: Difference between each phase resistance should be less than 0.5Ω.

    6. Is the ETS motor resistance within specifications?

      YES 

      • 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.
      NOTE: If PCM needs to be replaced, do "ETS Initialization" after it is replaced.

      NO 

      • Check ETS motor for contamination, deterioration, or damage. Substitute with a known-good ETS motor and check for proper operation. If the problem is corrected, replace ETS motor and then do "ETS Initialization". And go to "VERIFICATION OF VEHICLE REPAIR " procedure.
      NOTE: Procedure of ETS Initialization
      1. Erase the trouble codes on PCM
      2. Turn the ignition key on less than 1 second and turn it off (Do not start the engine)
      3. Turn the ignition key off and keep this condition until the main relay is turned off. (It will take 10 seconds)
      4. Turn ignition key on more than 1 second to record the throttle motor position on the EEPROM
