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 DLM controls the operation of the motor on the electronic differential. The DLM is attached to a bracket located on the left-hand (LH) side of the luggage compartment, immediately forward of the tail lamp, behind the trim.
The DLM receives three battery feeds from the auxiliary junction box (AJB) and an ignition feed from the central junction box (CJB). A connection with the high speed controller area network (CAN) bus allows the DLM to communicate with the ADCM.
