DTC Descriptor

DTC B3060 00

- 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 prerelease password via the serial data circuit to the engine control module (ECM).

If the transponder value does not match the learned key code 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.

* The security indicator will flash (Canada only).

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 or when a scan tool is used to clear DTCs.
