2002 Chevrolet Monte Carlo V6-3.4L VIN ESECTION Before Programming a Control Module
IMPORTANT:
^ Do NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customer's concern.
^ The Off-Board Programming is used in situations where a control module must be programmed without having the vehicle present. The Off-Board Programming Adapter must be used to perform the Off-Board Programming procedure. The adapter allows the control module to power up and allows the Tech 2 to communicate with the control module.
^ DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
Ensure that all connections are secure at the following locations:
^ The Off-Board Programming Adapter
^ The Tech 2
^ The control module
^ The Techline terminal
IMPORTANT: Do NOT program a control module unless you are directed by a service procedure or you are directed by a General Motors Corporation service bulletin. Programming a control module at any other time will not permanently correct a customers concern.
Ensure the following conditions are met before programming a control module: Vehicle system voltage
^ Vehicle system voltage
- There is not a charging system concern. All charging system concerns must be repaired before programming a control module.
- 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.
- A 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, such as the following components:
^ Twilight sentinel
^ Interior lights
^ Daytime running lights (DRL)-Applying the parking brake, on most vehicles, disables the DRL system. Refer to the Owners manual.
^ Heating, ventilation, and air conditioning (HVAC) systems
^ Engine Cooling fans, etc.
^ The 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.
^ All tool connections are secure, including the following components and circuits:
- The RS-232
- The connection at the data link connector (DLC)
- The 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
