Circuit/System Testing

WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the driver information center (DIC) switch.
  2. Ignition OFF, test for less than 1 ohm between the low reference circuit terminal 1 and ground.
    • If greater than the specified value, test the circuit for an open/high resistance.
  3. Ignition OFF, test for less than 1 ohm between the ground circuit terminal 5 and ground.
    • If greater than the specified value, test the circuit for an open/high resistance.
  4. Ignition ON, test for B+ between the following DIC switch signal circuit and ground.
    • DIC Switch Signal Circuit Terminal 2
    • DIC Select Menu Switch Signal Terminal 3
      • If less than the specified value, test the appropriate signal circuit for a short to ground. If the circuit tests normal, test or replace the IPC.
      • If greater than the specified value, test the appropriate signal circuit for a short to voltage. If the circuit tests normal, test or replace the IPC.
  5. Ignition ON, verify a test lamp illuminates between the appropriate DIC switch signal circuit and ground.
    • If the test lamp does not illuminate, test the appropriate signal circuit for an open/high resistance. If the circuit tests normal, replace the IPC.
  6. If all circuits test normal, test or replace the DIC switch.
