Stand-by Mode

WARNING: This page is about a different car, the 2010 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.

The memory control module supports a stand-by mode to keep power consumption to a minimum.

The control module will enter stand-by mode upon receipt of a local interconnect network (LIN) bus 'SLEEP' message from the central junction box (CJB). Alternatively, a time period of 3 seconds after the local interconnect network (LIN) bus network has remained quiet provided there are no motors being driven at that time and there are no valid switch requests.

If there is a failure with the local interconnect network (LIN) bus network then the seat will be operational in 'inch mode' only.

If the control module is being prevented from entering stand-by mode due to motor movement, memory recall or switch operation, then it will enter stand-by mode when the current function has terminated.

NOTE: In the case of a memory recall, all memory recall operations should be carried out before entering stand-by mode, not just the current motor movement.

The control module will exit stand-by mode if there is any local interconnect network (LIN) bus activity. When the control module exits stand-by mode it must verify the 'System Enable Status' in order to recognize when it should respond to a switch request.
