Circuit/System Testing

WARNING: This page is about a different car, the 2007 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 turn signal multifunction switch.
  2. Test for less than 5 ohms of resistance between the ground circuit and ground.
    • If greater than 5 ohms, test the ground circuit for an open/high resistance.
  3. Install a 3-amp fused jumper wire between the signal circuit and ground. Verify that the proper turn signal lamp is ON.
    • If the turn signals are not ON, test the left and right signal circuit of the turn signal multifunction switch for a short to voltage or an open/high resistance.
  4. If all circuits test normal, test or replace the turn signal multifunction switch.
