Stand-by Mode
WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. 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.
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 CAN bus activity.
The exchange of information between the diagnostic unit and the memory control module is via the medium-speed CAN bus. There is a non-volatile Electronic Erasable Programmable Read Only Memory (EEPROM) for saving detected errors. Its contents are not lost when the power supply is disconnected. Only the IDS diagnostic tester can erase the error memory.
