  3. Ignition OFF for 60 seconds, test for less than 5 ohms between the low reference circuit terminal 1 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance.
  4. Ignition ON, test for B+ between the ignition voltage circuit terminal 4 and ground.
