Circuit/System Testing

  1. Ignition OFF, disconnect the X1 harness connector at the CD changer.
  2. Test for less than 10 ohms between the ground circuit terminal 1 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 16 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. If all circuits test normal, replace the CD changer.
