Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. 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 5 ohms of resistance between the ground circuit terminal 7 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that all scan tool DIC Switch parameters are Inactive.
    • If any DIC switch parameters are not Inactive, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the instrument panel cluster (IPC).
  4. Ignition ON, install a 3-amp fused jumper wire between the signal circuit terminal 1 and the ground circuit terminal 7. Verify that all scan tool DIC switch parameters are Active.
    • If any is 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.
