WARNING: This page is about a different car, the 2008 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
    IMPORTANT: Before disconnecting the harness connector at the VDAAW module, ensure that the ignition has been OFF for at least 120 seconds. Failure to do so may result in component damage.
  1. Ignition OFF for 120 seconds, disconnect the harness connector at the VDAAW module.
  2. Ignition OFF, vehicle doors closed, test for less than 5.0 ohm between the ground circuit terminal 4 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
  4. Ignition OFF for 120 seconds, connect the harness connector at the VDAAW module. Disconnect the harness connector at the headlamp switch.
  5. Ignition ON, verify the scan tool Mode Switch parameter is Inactive.
    • If not the specified value, test the signal circuit terminal 9 for a short to ground. If the circuit tests normal, replace the VDAAW module.
  6. Install 3A fused jumper wire between the signal circuit terminal 9 and ground. Verify the scan tool Mode Switch parameter is Active.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the VDAAW module.
  7. Ignition OFF, connect the harness connector at the headlamp switch.
  8. Ignition ON, observe the scan tool Mode Switch parameter while cycling the lane departure warning switch. The parameter should change between Active and Inactive.
    • If the parameter does not change between the specified values, replace the headlamp switch.
  9. Observe the scan tool Mode LED parameter while cycling the lane departure warning switch. The parameter should change between On and Off.
    • If the parameter does not change between the specified values, replace the VDAAW module.
  10. Observe the mode LED while cycling the lane departure warning switch. The LED should turn ON and OFF when cycling between the commanded states.
    • If the LED is always OFF, test the control circuit terminal 16 at the headlamp switch harness connector for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, test or replace the headlamp switch.
  11. If all circuits test normal, replace the VDAAW module.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
