DTC Descriptor
DTC B3060 00 : Unprogrammed Transponder Identification Code ReceivedCircuit/System Description
When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized 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 an engine start
Conditions for Running the DTC
Ignition is in the Accessory or Run position.
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 center 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. |
