Circuit/System Testing

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the heated steering wheel control module.
  2. Test for less than 5.0 ohms between the ground circuit terminal B X1 and ground.
    • If greater than the specified value, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify a test lamp illuminates between the ignition voltage circuit terminal A X1 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
  4. Install a 3A fused jumper wire between the control circuit terminal A X2 and B+. Verify the heated steering wheel indicator is illuminated.
    • If the indicator does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the left steering wheel control switch.
  5. Verify that a test lamp does not illuminate between the indicator control circuit terminal A X2 and ground.
    • If the test lamp is always ON, test the indicator control circuit for a short to voltage. If the circuit tests normal, replace the heated steering wheel control module.
  6. If all circuits test normal, replace the heated steering wheel control module.
