Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the DIC switch.
  2. Test for less than 1 ohm of resistance between the DIC switch ground circuit and ground.
    • If greater than 1 ohm, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Trip/Fuel Switch parameter is Inactive.
    • If not inactive, test the signal circuit for a short to ground. If the circuit tests normal, replace the IPC.
  4. Install a 3-Amp fused jumper wire between the signal circuit and ground. Verify the scan tool Trip/Fuel Switch parameter is Active.
    • If not active, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the IPC.
  5. If all circuits test normal, test or replace the DIC switch.
