Stand-By Mode

WARNING: This page is about a different car, the 2006 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 LIN bus 'SLEEP' message from the Central Junction Box (CJB). Alternatively, a time period of 3 seconds after the 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 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 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.
