MSM DTC B2101-B2112: Switch Failed: Description

Memory Seat Module (MSM) receives inputs from left seat switch (Eldorado and Seville only) and left lumbar switch. When switch is operated, it becomes grounded. The input is recognized by MSM, which moves seat or lumbar support in appropriate direction. If MSM continues to receive input from seat or lumbar support switch for 30 seconds after motion in requested direction has ceased, switch is considered shorted. If a seat or lumbar position sensor DTC is currently set and a switch in the associated direction of suspect sensor has been active for 30 seconds, switch is considered shorted.

Appropriate MSM DTC will set when a switch failure is detected. When DTC is set, associated motor outputs of suspect switch will be deactivated. MSM will continue to respond to valid inputs from other manual switches. All memory recall commands will be ignored. DTC will clear when MSM does not detect switch failure during last monitoring cycle.
