B3060

DTC B3060

Circuit 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, learned key code. If the value is correct, the TDM sends a random generated number to the transponder. This is called a challenge. Both the transponder and the TDM perform a calculation on the challenge. If the calculations match, the TDM sends the fuel enable password via the serial data circuit to the powertrain control module (PCM). If either the transponders unique value or the calculation to the challenge is incorrect, the TDM will send the fuel disable password to the PCM via the serial data circuit.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B3060 Unprogrammed Transponder ID Code Received

This vehicle has DTCs which include DTC Symptoms. For more information on DTC Symptoms, refer to DTC Symptom Description. DTC Symptom Description






Conditions for Running the DTC

* The ignition switch is in the ACCESSORY or RUN position.
* DTC B1325 03 or B1325 07 is not current.

Conditions for Setting the DTC

If the transponder value from the ignition key does not match the one stored in memory, the TDM sets this DTC. This DTC indicates the use of a key with a transponder value that has not been learned by the TDM. The vehicle theft deterrent (VTD) system considers this to be a theft attempt.

Action Taken When the DTC Sets

* The vehicle will not start.
* The TDM sends a message via the serial data circuit to the body control module (BCM) to flash the SECURITY indicator.

Conditions for Clearing the MIL/DTC

* The TDM clears the current status of the DTC when it senses a valid, memorized, transponder value from the ignition key.
* The TDM clears the history status of the DTC after 100 fault-free ignition cycles.
* The DTC can be cleared by using a scan tool.

Test Description

Step 1 - Step 7:

The numbers below refer to the step numbers on the diagnostic table.
2. This step verifies the condition for setting DTC B3060 is current.
4. The only method to determine which re-learn procedure to perform.
5. To set this DTC, a key with a working transponder that is not learned was read by the theft deterrent control module. For that key to operate the vehicle and one or more learned keys are available, perform the Adding Keys procedure. Adding Keys
6. To set this DTC, a key with a working transponder that is not learned was read by the theft deterrent control module. For that key to operate the vehicle, a 10-Minute Re-Learn Procedure or 30-Minute Re-Learn Procedure must be performed.
