Circuit/System Testing

WARNING: This page is about a different car, the 2006 Buick Lucerne. 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/cooled seat switch.
  2. Ignition ON, test for B+ between the memory seat switch supply voltage circuit terminal 1 and ground.
    • If less than B+, test the supply voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the driver door module.
  3. Test for 0 volts between the memory switch signal circuit terminal 9 and ground.
    • If greater than 0 volts, test the signal circuit for a short to voltage.
  4. Ignition OFF, connect the harness connector at the heated/cooled seat switch.
  5. Ignition ON, verify the scan tool Driver Door Switch, Memory Recall Switches parameter changes state while pressing the memory 1 switch.
    • If the parameter does not change state, test the memory switch signal circuit terminal 9 for a short to ground or an open/high resistance. If the circuit tests normal, perform the Memory Switch component test. If the switch tests normal, replace the driver door module.
  6. Verify the scan tool Memory Recall Switches parameter changes state while pressing the memory 2 switch.
    • If the parameter does not change state, replace the heated/cooled seat switch.
  7. Verify the scan tool Memory Recall Switches parameter changes state while pressing the EXIT switch.
    • If the parameter does not change state, replace the heated/cooled seat switch.
  8. If all circuits test normal, replace the memory seat module.
