Circuit/System Testing
WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the heated/cooled seat switch.
- 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.
- 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.
- Ignition OFF, connect the harness connector at the heated/cooled seat switch.
- 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.
- 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.
- 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.
- If all circuits test normal, replace the memory seat module.
