NOTE:
Do not cut the power to the central electronic module (CEM) unless it is the last
control module left to check.
NOTE:
After fault with control modules that interfere with communication, other control
modules may remain in Limp-Home (that is, they work with reduced
functionality) even when the ignition has been turned off and on a few times.
For certain faults in the CAN-net where control modules have stopped
communicating, it may help to disconnect/reconnect the battery to "restart" the
control module/CAN-net.
