1. Verify the following for the setup:

•	The battery is charged.

•	The ignition is ON.

•	The battery/cigarette lighter connection is secure.

•	The data link connector (DLC) is attached.

2. Perform the programming. Refer to the up to date Techline terminal/equipment for user instructions.
3. Perform the Passlock Learn Procedure. Refer to Programming Theft Deterrent System Components in Theft Deterrent.
4. After the vehicle has been programed, operate the vehicle until the coolant temperature is more than 77°C (170°F). This will allow the top dead center (TDC) offset to be programed. Refer to Programming the TDC Offset below.
5. Check the Data list for a TDC offset.
6. If the PCM fails to reprogram, do the following:

•	Check all the powertrain control module (PCM) connections.

•	Check the Techline terminal/equipment for the latest software version.

•	Try again to reprogram the PCM. If the PCM fails again, replace the PCM. Refer to Powertrain Control Module Replacement .

The PCM will automatically activate the TDC offset program when the engine coolant is more than 77°C (170°F). If the PCM is not programmed with a TDC offset, a DTC P1214 will set.
