If you have heard of flashing, reflash, programming, reprogramming, and software updates when it comes to vehicles they are all universal words for vehicle programming. It can be installing a new module and loading software or updating software in an existing module. Setting up security, vehicle build data, and resetting parameters are all part of vehicle programming. Some may use the terms programming, reprogramming, and software updates as more familiar terms, since most people have already experienced those things with their own laptops or cell phones.

A vehicle has a maze of wires and computers. Collectively, the electronics in a vehicle are known as the CAN. The Controller Area Network (CAN) is incredibly complex. Vehicles are essentially like a computer with wheels and your car can be considered the computer network.

Throughout the car are various modules (computers) called electronic control units, or ECUs. Each ECU has several jobs such as controlling the engine or transmission, security functions, and miscellaneous functions, like rolling up windows, unlocking doors, etc.

Eventually a directive was standardized for vehicle communication called, On-Board Diagnostic Protocol (known as OBD-II). This updated protocol required a CAN network to efficiently connect all the engine sensors and ECUs for a self-diagnosis. If an ECU detects a problem, it broadcasts an alphanumeric code and the check engine light is turned on to let you know there may be an issue with the vehicle. The next step is to use a scan tool to read codes in order to properly diagnose the vehicle for that particular issue.

A program is the process of installing (flashing) software into a module after that module has been replaced. Many vehicles now require a programming event even when seemingly normal service repairs, like battery replacements, are done. This requires special equipment and software.

A reprogram is when the current operating software in a module or modules is changed or updated in order to operate differently. Reprogramming a module is done to either correct emission issues or resolve issues affecting the operation of a specific system. When an issue becomes a common problem, a TSB (Technical Service Bulletin) will be issued by the vehicle manufacturer with a software update (if applicable) to correct that issue. You can verify a TSB based on the VIN, production date of the vehicle, and any OBD code relevant to the issue. Once verified the ECU software can then be updated to the latest calibration.

Who can do this for you? Well Go Powertrain of course!

Go Powertrain offers a mobile vehicle programming service!

Using a mobile service means you don’t have to invest your time and money into programming technology. Getting a return on your investment can be very difficult and it takes an average 2 vehicles per day to pay for the equipment and subscriptions to the OEM manufacturers.

Go Powertrain can do programming on most domestic, Asian, and European vehicles.

• Computer module programming, setups, and initializations (ECU, ECM, PCM, TCM, etc)
• Immobilizer resetting
• Key programming
• View and set engine parameters
• J2543 programming capability
• Original equipment capability for fault codes, live data, actuation tests, adaptations, and coding for most vehicles

We do a light diagnostic on the vehicle first to determine the issue. Then we can program or reprogram depending on the issue. Programming can help with driveability problems such as

• Transmission issues (poor shifting)
• Engine misfires (stumbling or hesitation)
• Catalytic Converter (emissions)
• And more

Advantages to using a mobile vehicle programming service!

• No towing required, we come to you
• Won’t tie up a bay, we’ll program where the car is parked
• Flat fee – lower than dealers
• Same day appointments
