ISC Servo Motor

  1. Turn ignition switch to "OFF" position. Disconnect ISC servo connector. Check motor coil continuity between terminals "1" and "4". Resistance should read between 7 and 10 ohms. If resistance is 0 ohms or abnormally large, open or short circuit exists in motor coil. Replace ISC servo assembly.
  2. Make sure there is no continuity between terminal "1" or "4" and injection mixer body. If continuity exists, there is a short circuit in coil. Replace ISC servo assembly.
