6. Turn the ignition OFF and ON again, but do not
crank or start the engine. The ECM will reset the
ECM ID code to match the new ID code that was
calculated and sent by the immobilizer control unit
when the ignition was first turned ON after the reset
command.
7. Return the system to the normal mode.
8. Turn OFF the ignition.
9. Turn ON the ignition.
10. Start the engine.
After reprogramming the ID code, the scan tool SYS-
TEM DIAGNOSIS command can verify that the ECM ID
code matches the immobilizer control unit ID code.
If the reprogramming procedure does not result in
matching ID codes, check the electrical connectors for
the serial data wire between the immobilizer control unit
and the ECM.
TRANSPONDER
Each valid ignition key has an internal transponder
which is a read /write transponder.
The transponder contains an implementation of a cryp-
to-algorithm with 96 bits of user configurable secret-key
contained in EEPROM and transmits data to the ICU by
modulating the amplitude of the electromagnetic field,
and receives data and commands in a similar way.
