DTC B2130-B2133: Memory Key Failed: Description

Memory Mirror Module (MMM) receives inputs from memory function switch. When a switch is operated, it becomes grounded. MMM recognizes each input, performs the requested action and sends a class 2 message to MSM. MSM then also performs the requested action. When any memory function switch input continues to be active for 30 seconds after motion in requested direction has ceased, switch is considered shorted.

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