DTC Descriptor

DTC B3060 00 : Unprogrammed Transponder Identification Code Received Malfunction

When an ignition key is inserted into the transmitter slot and the power mode is changed, the transponder embedded in the head of the key is energised by the exciter coils. The energised transponder transmits a signal that contains its unique value, which is received by the body control module (BCM). The BCM then compares this value to a value stored in memory. If the value is not correct, the BCM disables engine start.

Conditions for Running the DTC

Vehicle is ON or in Service Mode.

Conditions for Setting the DTC

The transponder value measured by the BCM is incorrect or not learned to the vehicle.

Action Taken When the DTC Sets

•	Vehicle starting will be disabled.

•	The security indicator in the instrument cluster will be illuminated. The driver information centre will display a service message.

Conditions for Clearing the DTC

•	A current DTC will be cleared when the BCM detects a valid transponder value from the ignition key.

•	A history DTC will be cleared after 100 malfunction-free ignition cycles or when a scan tool is used to clear DTCs.
