Battery Backed Sounder

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2015 Jaguar XF, 2014 Jaguar XF, 2013 Jaguar XF, 2012 Jaguar XF, and 2011 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

Operation of the battery backed sounder is controlled by the CJB on the LIN bus. The sounder is also connected with a permanent battery supply via the CJB. An integral, rechargeable battery powers the sounder if the battery power supply from the CJB is interrupted.

Dependent on vehicle, a incitation sensor is incorporated into the battery backed sounder, to monitor vehicle attitude, see Inclination Sensor.
