1、、、、The Body Control Module introduce
The interface of the body control module is connected with the interface of EMS
controller and LF antenna. The frequency is Writing-reading L
134.744kHz
assembled on the lock core, sending the data between the Transponder and the BCM.
When the key is inserted the lock core and rotated to “ON”, the Transponder
assembled in the key is doing double encrypted data traffic between writing-reading
LF antenna and BCM. BCM will check the results; meanwhile, it will do the
encrypted certifying with EMS controller. When the two parts are confirmed and no
error, BCM would allow the EMS controller to start the engine.
The device is generally installed under the dashboard. The LF antenna is installed
in the igniting lock core. Transponder is embedded in the igniting key. First using
tester to matching the key through diagnosis interface, then the key is certified. When
using this system, make sure all parts installed strongly, connecting between pins and
the controller reliable. During the process of key matching and EMS controller, make
sure to follow the matching process strictly, and keep other keys away from LF
antenna, which should be more than 5cm distance.
There have two kinds of product, the difference is about the hull, the PCBA
layout is the same.
F antenna is
