Diagnostic Information and Procedures
Detecting Item
Immobilizer Control System:
Detecting Condition
Transponder code in the transponder built in
the ignition key cannot be read through
immobilizer control module (ICM).
• While registering the transponder code in
the transponder built in the ignition key in
ECM, the keyless start control module sent
a signal to ECM indicating that the ID code
could not be registered.
• The ID code could not be registered in the
keyless start control module or ECM.
ECM detects different ID codes registered in
ECM and keyless start system.
Reception error of communication data for
keyless start control module is detected for
longer than specified time continuously.
Communication error between immobilizer
control module (ICM) and ECM is detected by
ECM.
EEPROM in ECM is corrupted.
Transponder code in the transponder built in
the ignition key is invalid.
Immobilizer control module (ICM) is faulty.
Communication error between ECM and
BCM is detected by ECM.
• Communication error between ECM and
BCM is detected by ECM.
• Wrong ECM or BCM is used.
