DTC Descriptor
DTC B3060: Unprogrammed Transponder Identification Code Received
Circuit/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 theft deterrent module (TDM). The TDM then compares this value to a value stored in memory. This stored value is the learned key code. If the value is correct, the TDM will send the fuel continue
password via the serial data circuit to the engine control module (ECM). If the learned key code does not match or a transponder value is not received, the TDM will send the start disable password to the ECM.
Conditions for Running the DTC
Ignition is in the Accessory or Run position.
Conditions for Setting the DTC
The transponder value measured by the TDM is incorrect or not learned to the vehicle.
Action Taken When the DTC Sets
• | Vehicle starting will be disabled. |
• | The security indicator will be illuminated. |
Conditions for Clearing the DTC
• | A current DTC will be cleared when the TDM detects a valid transponder value from the ignition key. |
• | A history DTC will be cleared after 100 malfunction-free ignition cycles. |

Circuit/System Verification
Important: When using this diagnostic, more than one vehicle key is required to ensure proper diagnosis. If more than one key is not available at the time of service, contact the customer and ask if any other keys can be provided
for service. If unavailable, a new second key can be created.
- Perform the 10-Minute Vehicle Key Relearn procedure. Refer to
Replacing Keys
.
- While viewing the scan tool VTD States parameter, turn ON the ignition with each of the available vehicle keys. The parameter should read Normal Decision with all available keys.
⇒ | If not the specified value, replace the appropriate key. |
