Circuit Description



The memory seat module (MSM) receives voltage inputs from the tilt/telescope switch based on the position of the switch. The MSM then supplies



battery voltage and a ground to the tilt or telescope motor control circuits depending on which direction of movement is requested.



Conditions for Running the DTC



The ignition ON.



Conditions for Setting the DTC



The MSM detects a tilt or telescope switch input for more than 30 consecutive seconds after the tilt or telescope motor movement has stopped.



Action Taken When the DTC Sets



* The tilt or telescope motor will be deactivated.



* Memory recall functions will be disabled.



Conditions for Clearing the DTC



* A current DTC will clear when the failed switch input is no longer active.



* A history DTC will clear after 100 ignition cycles.



Diagnostic Aids



An intermittently stuck tilt or telescope switch may cause a DTC to set.
