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 vehicle keys.

瀚慖f not a correct vehicle key, replace the key.

2. While viewing the scan tool TDM Transponder Key parameter, turn ON the ignition with each of the available vehicle keys. The parameter

should read Present with all available keys.

瀚慖f only one key results in the parameter reading Not Present, replace the appropriate key.

瀚慖f all available keys result in the parameter reading Not Present, replace the TDM.

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.
