Instrument Panel (I/P) Circuit Testing

WARNING: This page is about a different car, the 2007 Saturn Outlook. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the I/P.
  2. Test for less than 1.0 ohm of resistance between the ground circuit and ground.
    • If greater than 1.0 ohm, test the ground circuit for an open/high resistance.
  3. Connect a test lamp between the control circuit and the ground circuit.
  4. Ignition ON, turn ON the appropriate turn signal. The test lamp should flash.
    • If the test lamp remains ON all the time, test for a short to voltage on the control circuit. If the circuit tests normal, test or replace the BCM.
    • If the test lamp remains OFF all the time, test for a short to ground or an open/high resistance on the control circuit. If the circuit tests normal, test or replace the turn signal multifunction switch.
  5. If all circuits test normal, replace the I/P.
