For 1990-2009 cars

### DTC Descriptor

DTC B3060 : Unprogrammed Transponder Key Identification Code Received

### Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle .

### 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 energised by the exciter coils surrounding the ignition lock cylinder. The energised 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 start enable password via the serial data circuit to the engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect, the TDM will send the start disable password to the ECM.

### Conditions for Running the DTC

Ignition is in the ACC or ON 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 disable.

• | The security warning lamp will illuminate.

• | The security warning lamp will flash.

### Conditions for Clearing the DTC

• | A current DTC will clear when the TDM detects a valid transponder value from the ignition key.

• | A history DTC will clear after 100 fault-free ignition cycles.

• | The DTC can be cleared using a scan tool.
