ISC Servo Motor

  1. Turn ignition switch to "OFF" position. Disconnect ISC servo connector. Check motor coil continuity between terminal Nos. 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 Nos. 1 or 4 and injection mixer body. If continuity exists, there is a short circuit in coil. Replace ISC servo assembly.
