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 reading lamp switch.
  2. Test for less than 1.0 Ω of resistance between the ON circuit and ground.
    • If greater than 1.0 Ω, test the ON circuit for an open/high resistance.
  3. Install a test lamp between the signal circuit and ground. Verify the test lamp turns ON.
    • If the test lamp does not turn ON, test the signal circuit of the reading lamp switch for a short to ground or an open/high resistance.
  4. If all circuits test normal, test or replace the reading lamp assembly or the reading lamp bulb.
