Engine Wont Crank After Battery Disconnect, Dead Battery Condition or After A Reprogramming Event, Theft Deterrent Light Illuminated, DTC B3060 Stored, (Reprogram Keys into Theft Deterrent Module)

Some customers may comment on the following conditions after experiencing a loss of battery power in their vehicle. Technicians may encounter a vehicle with the following conditions after disconnecting a battery during a service procedure or after reprogramming any module on the vehicle.

Technicians may find Diagnostic Trouble Code (DTC) B3060 (Unprogrammed Transponder Identification Code Received) stored as a current or a history code.

This condition may be caused by the failure of the key programming information for both keys to be permanently stored in the Theft Deterrent Module (TDM) during the vehicle assembly process. The information for one key is stored permanently while the information for the other key will be lost if the vehicle's battery voltage drops below 7.8 volts.

The failure condition will also occur when the key programming information for one of the vehicle's keys is lost after a battery disconnect during a service procedure, a dead battery condition or after a reprogramming event for any module and the key that has lost its programming is used to start the vehicle. The vehicle's other key programming information will not be lost due to the loss of battery voltage or a reprogramming event and that key will still start the vehicle. It may also be possible to unknowingly render the customer's second key inoperative after a battery disconnect or a reprogramming event performed during other service procedures on the vehicle.

It is recommended that the customer be asked for both keys to their vehicle when their vehicle is brought in for any service requests in which a battery disconnect or reprogramming event will occur. Technicians should verify that both keys work before returning the vehicle to the customer.

Important: In order to prevent the technician from possibly having to perform a very long diagnostic procedure, every effort should be made to obtain both keys to the vehicle before any repairs are attempted on the vehicle. If the customer only brings in one key, their second key will no longer start the vehicle after these repairs are completed unless the second key is programmed into the TDM at a later date using the Adding Keys procedure. Having both keys available will also prevent the possible situation where the second key cannot be programmed into the TDM and the vehicle would have to be returned to the dealership again.

Technicians should use one of the following procedures to repair this condition depending on the number of keys available:

Procedure #1. Both keys available at dealership. One key starts the vehicle but the second key does not.

1. Make sure that the vehicle's battery is fully charged before attempting this procedure.
2. If you have one key that starts the vehicle, use the Adding Keys procedure in SI (Document ID# 1686394) to program the second non-working key into the TDM.
3. If the second key cannot be programmed, then replace the non-working key and program the new key into the TDM using the Adding Keys procedure in SI. The new key must be the correct part number with a circle plus mark on the key shank.
4. If both keys now start the vehicle, clear all DTCs and return the vehicle to the customer.
5. If one key still does not start the vehicle, refer to the Diagnostic System Check-Vehicle procedure in SI to begin your diagnosis.

Procedure #2. One key available at the dealership that will not start the vehicle. Second key not available.

1. Make sure that the vehicle's battery is fully charged before attempting this procedure.
2. Program the available key into the TDM using one of the following programming methods:

•

For Domestic vehicles, technicians may use the either the 10-Minute or the 30-Minute Relearn Procedure using a single key. If the 10-Minute Relearn procedure is used, select the "Vehicle Theft Deterrent Learn For Learning Replacement Keys" calibration in the service programming system. Refer to the Set Up a Theft Deterrent Module (TDM) Using New Keys section of the Programming Theft Deterrent System Components (Domestic) procedure in SI (Document ID# 1686399).

•

For Canadian vehicles, technicians must use the 10-Minute Relearn Procedure to learn the first key. The calibration "Vehicle Theft Deterrent Learn For Learning Replacement Keys" must be selected in the service programming system. Refer to the Set Up a Theft Deterrent Module (TDM) Using New Keys section of the Programming Theft Deterrent System Components (Canada) procedure in SI (Document ID# 1686437).

•	For Saturn vehicles, technicians must refer to the Theft Deterrent Control Module Programming and Setup procedure in SI (Document ID# 1864651). Use the Set Up a Theft Deterrent Module (TDM) Using New Keys procedure contained in this document.

3. If the first key cannot be programmed using either the 10-Minute or 30-Minute Relearn Procedure, then replace the first key with a new key. Use the appropriate procedure above to program the new key into the TDM. The new key must be the correct part number with a circle plus mark on the key shank.
4. After the first key or the new replacement key is successfully programmed into the TDM, instruct the customer to bring their second key to the dealership. Program the second key into the TDM using the Adding Keys procedure in SI.
5. If both keys now start the vehicle, clear all DTCs and return the vehicle to the customer.
6. If one or both of the keys you now have cannot be programmed into the TDM, refer to the Diagnostic System Check-Vehicle to begin your diagnosis.

For vehicles repaired under warranty, use:

Important: If the 30 minute key learn procedure is used, the additional labor time must be authorized by your service manager.
