Stop/Start Control Scheme (Freelander 2)

New software has been added to the ECM that controls the operation of the automatic system "Stop/Start", because in addition to its own components, the automatic system "Stop/Start" connected to many other vehicle systems. Sophisticated technology connects these systems, and the many signals used in the system "Stop/Start", are transmitted to the ECM and through the CJB, which also received the updated software. The control logic for blocking the engine shutdown during the Start/Stop cycle is located in the CJB. The CJB also acts as a gateway that relays this information to the ECM over the medium and high speed CAN buses.

To apply the system "Stop/Start" eight wiring harnesses have been changed.

Automatic system control scheme "Stop/Start":

NOTE: A = Wired connection; D = High speed CAN bus; N = Medium speed CAN bus; O = LIN bus; AC = diagnostic channel.
