PCM Programming (Cab & Chassis, Chevy Express, Cutaway, RV Cutaway, Savana, Savana Camper Special & Savana Special - 6.5L)

WARNING: This page does not describe the selected car, but rather 120 other vehicles, including the 2002 Saturn Vue, 2002 Saturn SL2, 2002 Saturn SL1, 2002 Saturn SL, and 2002 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
  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. See the up to date Techline terminal/equipment for user instructions.
  3. Perform the Passlock™ Learn Procedure. See THEFT DETERRENT SYSTEM COMPONENTS .
  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 .
  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. See appropriate REMOVAL, OVERHAUL & INSTALLATION article.
