General Description

Immobilizer is device that prevents car from being thieved by reproduced key. Major components of immobilizer are ECM (Engine Control Module) and SMARTRA. Besides them, Immobilizer has transponder and coil antenna in it. If driver inserts key into key hole, SMARTRA gets transponder signal by wireless communications via coil antenna and delivers it to ECM through K-line communication line. then ECM deciphers code in it. If inserted key has invalid transponder with incorrect code or doesn't have transponder in it, ECM judges that inserted key is reproduced key and prohibits engine starting.

DTC Description

The ECM sets DTC P1610 if Non Immobilizer EMS is installed on vehicle equipped with Immobilizer.
