Remote Programming (Alero - 3.4L, Aurora, Bonneville, Camaro, Century, Deville, Eldorado, Firebird, Grand Am, Grand Prix, Impala, Intrigue, LeSabre, Malibu, Monte Carlo, Park Avenue, Regal & Seville)
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.
NOTE:
After replacing Powertrain Control Module (PCM) or if program needs to be updated, refer to latest Techline information on PCM reprogramming. PCM can only be programmed using Tech 2™ and Techline terminal, or by using a personal computer equipped with the current service programming system software installed.
NOTE:
DO NOT program a control module unless you are directed by a service procedure or you are directed by a technical service bulletin. Programming a control module at any other time will not permanently correct a customer's concern.
Before Remote Programming A Control Module
- Vehicle system voltage:
- Ensure there is no charging system concern. All charging system concerns must be repaired before programming a control module.
- Ensure battery voltage is greater than 12 volts but less than 16 volts. The battery must be charged before programming the control module if the battery voltage is low.
- Ensure battery charger is NOT connected to the vehicle's battery. Incorrect system voltage or voltage fluctuations from a battery charger, may cause programming failure or control module damage.
- Turn off or disable any system that may put a load on the vehicle's battery.
- Twilight sentinel.
- Interior lights.
- Daytime Running Lights (DRL). Applying the parking brake, on most vehicles, disables the DRL system.
- Heating, Ventilation and Air Conditioning (HVAC) systems.
- Engine cooling fans, etc.
- Ensure ignition switch is in the proper position. The scan tool prompts you to turn ON the ignition, with the engine off. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
- Ensure all tool connections are secure.
- RS-232.
- The connection at the Data Link Connector (DLC) is secure.
- Voltage supply circuits.
- DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
Remote Programming Procedure
- Turn ignition off.
- Install the Tech 2™ to the data link connector (DLC).
- Turn ignition on, with engine off.
- Turn off all vehicle accessories.
- With the Tech 2™, select Service Programming.
- Identify vehicle information as requested by the Tech 2™.
- Select the type of module you are programming.
- Select the type of programming to be performed.
- Verify the displayed VIN with the vehicle VIN. If the displayed VIN does not match the actual VIN, write down the actual VIN and correct the VIN at the Techline™ terminal.
- When complete, exit Service Programming.
- Turn off the Tech 2™ and disconnect the Tech 2™ from the vehicle.
- Turn ignition off.
- Connect the Tech 2™ to the Techline™ terminal.
- Select Service Programming.
- Select Tech 2™ as the tool you are using.
- Select the type of programming to be performed.
- Verify the displayed VIN with the vehicle VIN. Correct the VIN as necessary.
- Select the type of module you are programming.
- Identify what type of programming that you are performing.
- Normal. This type of programming is for updating an existing calibration or programming a new controller.
- Vehicle Configuration Index (VCI). This selection is used if the vehicle VIN is unavailable or not recognized by the Techline™ terminal. You will need to contact the Techline™ Customer Support center to use this option.
- Reconfigure. This is to reconfigure a vehicle, such as tire size and axle ratio changes.
- Select the appropriate calibration file.
- Ensure all connections are secure.
- Select Reprog to initiate the download of the new calibration to the Tech 2™.
- After the download is complete, turn off the Tech 2™.
- Disconnect the Tech 2™ from the Techline™ terminal.
- Install the Tech 2™ to the data link connector (DLC).
- Turn ON the Tech 2™.
- Turn ignition on, with engine off.
- Select Service Programming.
- Select Program.
- After the download is complete, EXIT Service Programming.
- Turn ignition off for 30 seconds.
- Turn off the Tech 2™.
- If a control module is replaced the following service procedures must be performed: CKP System Variation Learn Procedure. See CRANKSHAFT POSITION SENSOR SYSTEM VARIATION LEARN PROCEDURE . Oil Life System - Resetting. See ENGINE OIL LIFE RESET. INSPECTION/MAINTENANCE COMPLETE SYSTEM SET PROCEDURE, see appropriate SELF-DIAGNOSTICS article. Programming Theft Deterrent System (except Camaro and Firebird). See THEFT DETERRENT SYSTEM COMPONENTS .
NOTE:
DO NOT turn off the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all the PCM and DLC connections are secure and the Techline™ operating software is up to date. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module. See appropriate REMOVAL, OVERHAUL & INSTALLATION article.
Remote Programming Verification
- With a scan tool, clear the DTCs.
- Attempt to start engine.
- Repeat the Service Programming procedure if the engine does not start or operates poorly. Perform the following procedures before programming the PCM:
- Ensure control module and DLC connections are okay.
- Ensure Techline™ operating software is up to date.
- Ensure calibration part number is correct for the vehicle.
- Attempt to program the control module. If the control module still cannot be programmed properly, replace the control module. See appropriate REMOVAL, OVERHAUL & INSTALLATION article. You must program the replacement control module.
