Battery voltage through the TILT/TELE SW/MEM SEAT MOD 10A located in the body control module fuse block is supplied at all times to the memory seat adjuster switch. When the memory recall switches are pressed they send a 12-volt signal to the memory seat module (MSM) indicating the memory recall request. In response to this signal, the MSM commands the driver seat motors to move to the appropriate seat positions stored in memory.

The memory seat module is also referred to as the Driver Position Module in certain scan tool menus.

1. Ignition OFF, disconnect the harness connector at the memory seat adjuster switch.
2. Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal C and ground.

⇒	If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

3. Install a 3A fused jumper wire between the B+ circuit terminal C and the signal circuit terminal A. Verify the scan tool Memory 1 Select Switch parameter is Active.

⇒	If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the MSM.

4. Install a 3A fused jumper wire between the B+ circuit terminal C and the signal circuit terminal B. Verify the scan tool Memory 2 Select Switch parameter is Active.

⇒	If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the MSM.

5. If all circuits test normal, test or replace the memory seat switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
