^ The battery is charged.
^ The ignition is ON.
^ The battery/cig. lighter connection is secure.
^ The data link connector (DLC) is attached.
2. Perform the programming procedure. Refer to up-to-date Techline terminal/equipment for user instructions.
3. Perform the Password Learn Procedure Seed and Key. Refer to Programming Theft Deterrent System Components in Antitheft and Alarm Systems.
4. After the vehicle has been programmed, operate the vehicle until the coolant temperature is more than 77°C (170°F). This will allow the TDC offset to be programmed. Refer to PCM Programming, or the TDC offset, if necessary.
5. If the PCM is only being reprogrammed, the PCM maybe necessary to perform a Glow Plug System Relearn. Refer to Glow Plug System Relearn Procedure.
6. If the PCM fails to reprogram, do the following:
^ Check all of the PCM connections.
^ Check the Techline terminal/equipment for the latest software version.
^ Try again to reprogram the PCM. If the reprogramming fails again, replace the PCM. Refer to Powertrain Control Module (PCM) Replacement.
