Circuit/System Testing

  1. Ignition ON, test for battery voltage between the battery positive voltage circuit of the DLC and ground.
    • If less than battery voltage, repair the voltage supply circuit for a short to ground or an open/high resistance.
  2. Test for less than 1 ohm of resistance between the ground circuit of the DLC and ground.
    • If greater than 1 ohm, repair the ground circuit for an open/high resistance.
  3. If all tests normal, refer to the scan tool/CANdi module user guide.
