DTC DESCRIPTOR

DTC B3060
Unprogrammed Transponder Identification Code Received

DIAGNOSTIC FAULT INFORMATION
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Testing and Inspection

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 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 Accessory or Run position.

CONDITIONS FOR SETTING THE DTC
The TDM is unable to measure the ignition key transponder value.

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 or when a scan tool is used to clear DTCs.

DIAGNOSTIC AIDS
A damaged or missing transponder, a non-Passkey III+ (PK3+) key, or a damaged exciter will cause DTC B3060 to set.

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.

1. Inspect all available vehicle keys that they are correct PK3+ keys and that the molded head is undamaged.
- If damaged or not a correct PK3+ key, replace the key.
2. While viewing DTCs with a scan tool, attempt to start the vehicle using all of the available keys. The vehicle should start with all available keys.
- If only one key results in inoperative starting and DTC B3060 is set as current, replace the suspect key.
- If all available keys result in inoperative starting and DTC B3060 is set as current, replace the TDM.

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests

- Replacing Keys
- Adding Keys (Domestic)
- Control Module References for Theft Deterrent Module replacement, setup, and programming.
