1. Set the ignition switch to the OFF position.
2. Ground the memory seat diagnostic connector.

• | The connector may be taped up into the harness.

• | The module beeps once in order to acknowledge entrance into the mode 1 diagnostics.

• | Refer to Memory Seat Operation in Seats for a detailed explanation of the memory seat/mirror module diagnostic modes.

3. Remove ground from the memory seat diagnostic connector, then ground the connector again within 5 seconds. (The module beeps twice in order to acknowledge entrance into the mode 2 diagnostics.
4. Operate the seat switch and the mirror switch in all directions. (The module beeps once for each open or short circuit to a position sensor or any position sensor discontinuity.)
5. Any time a switch is operated and the module beeps, the module senses a problem with the position sensor.

Is there any switch operation where the memory seat/mirror module beeped?
