    • 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. See the up to date Techline terminal/equipment for user instructions.

  4. After the vehicle has been programed, operate the vehicle until the coolant temperature is more than 170°F (77°C). This will allow the Top Dead Center (TDC) offset to be programed. See FUEL INJECTION PUMP TOP DEAD CENTER OFFSET ADJUSTMENT  .

  6. If the PCM fails to reprogram, do the following:
    • Check all the Powertrain Control Module (PCM) connections.
