DTC Table: ECM

DTC No.	Detecting Item	Detecting Condition	Immobilizer Indicator Light
P1614 - DTC P1614: Transponder Response Error	Transponder response error	Transponder code in the transponder built in the ignition key cannot be read through ICM.	Flash
P1615 - DTC P1615: Steering Lock Unit Communication Error (for Vehicle with Keyless Start System)	Steering lock unit communication error (for vehicle with keyless start system)	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 remote controller ID code could not be registered. The remote controller ID code could not be registered in the keyless start control module or ECM. And, the registration procedure of the transponder code in the transponder built in the ignition key was terminated forcibly.	Flash
P1616 - DTC P1616: Unregistered Keyless Start Control Module (for Vehicle with Keyless Start System)	Unregistered keyless start control module (for vehicle with keyless start system)	ECM detects different ID codes registered in ECM and keyless start system.	Flash
P1618 - DTC P1618: Keyless Start Control Module CAN Communication Error (for Vehicle with Keyless Start System)	Keyless start control module CAN communication error (for vehicle with keyless start system)	Reception error of communication data for keyless start control module is detected for longer than specified time continuously.	Flash
P1621 - DTC P1621: Immobilizer Communication Line Error	Immobilizer communication line error	Communication error between ICM and ECM is detected by ECM.	Flash
P1622 - DTC P1622: EEPROM Error	EEPROM reading/writing error	EEPROM in ECM is corrupted.	Flash
P1623 - DTC P1623: Unregistered Transponder	Unregistered transponder	Transponder code in the transponder built in the ignition key is invalid.	Flash
P1625 - DTC P1625: Immobilizer Antenna Error	Immobilizer antenna error	ICM is faulty.	Flash
P1636 - DTC P1636: Immobilizer Information Registration Failure	Immobilizer information registration failure	Communication error between ECM and BCM is detected by ECM.	No operation
P1638 - DTC P1638: Immobilizer Information Mismatched	Immobilizer information mismatched	The immobilizer control system information in ECM and the one in BCM does not match. The registration of the immobilizer control system information in ECM is failed.	No operation
P1645 - DTC P1645: ID Code Communication Error	ID code communication error	No response from ID controller.	Flash or light up
P1646 - DTC P1646: ID Code Incorrectness	ID code incorrectness	Different ID codes registered in ECM and ID controller. Communication error of ECM. Transponder code is not registered in ECM.	Flash or light up
