Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the DIC switch assembly.
  2. Verify all of the scan tool DIC Switch parameters except the TRIP/FUEL parameter are Inactive.
    • If not Inactive, replace the IPC.
  3. Ignition ON, install a 3-amp fused jumper wire between the signal circuit and ground. Verify all of the scan tool DIC Switch parameters except the TRIP/FUEL parameter are Active.
    • If not Active, test the signal circuit of the DIC switch assembly for a short to voltage. If the circuit tests normal, replace the IPC.
  4. If all circuits test normal, test or replace the DIC switch assembly.
