Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the DIC.
  2. Ignition OFF, test for less than 1 ohm of resistance between the DIC ground circuit and ground.
    • If greater than 1 ohm, test the ground reference circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates when connected between the DIC battery positive voltage circuit and ground.
    • If the test lamp does not illuminate, test the battery positive voltage circuit for an open/high resistance. If the circuit tests normal, replace the DIC.
