Memory Seat Operation 
 in Seats for a detailed explanation of
the memory seat/mirror module diagnostic  modes. |  
  
- 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.
 
- 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.)
 
- Any time a switch is operated and the module beeps, the module
senses a problem with the position sensor.
