Transponder; Coil Antenna; Immobilizer Rf Ic; Immobilizer Unit - SSANGYONG 2004 Rexton 2.7XDi Workshop Manual

COMPONENTS

Transponder

It receives the "ENERGY" and "CHALLENGE" signals and
computes them by the crypto key in ASCI and sends the "RE-
SPONSE" and serial number

Coil Antenna

Ls (inductance): 1.08 mH
It provides the "ENERGY" and "CHALLENGE" to the transponder, receives the output signals from the transponder, and
delivers them to the immobilizer ECU. It is installed at the top of steering handle lock. It uses the active type to enhance
the sensitiveness and stability.

Immobilizer RF IC

It drives the coil antenna, converts the received signals from the coil antenna to special code, and delivers it to the
immobilizer ECU.

Immobilizer Unit

It analyzes the received signals from the immobilizer RF IC, confirms the authorized transponder, and delivers the result
(start or start inhibition) to the engine ECU.
Engine ECU
It provides the start or start inhibition command by using the transponder related information from the immobilizer ECU
when turning on the ignition switch.
Diagnostic Tester
