Question 1

What is ECM, PCM, BCM, and TCM programming, and why would my vehicle need it?

Accepted Answer

These are different types of vehicle control modules—essentially the computers that manage key systems in your car:

• ECM (Engine Control Module) manages engine performance and efficiency
 • PCM (Powertrain Control Module) oversees both the engine and transmission systems
 • BCM (Body Control Module) controls functions like power windows, lights, and locks
 • TCM (Transmission Control Module) regulates how your transmission shifts gears

Programming these modules means updating or reconfiguring their software to correct errors, improve performance, or ensure compatibility with replaced parts. Your vehicle may need programming after repairs, part replacements, or if you're experiencing system-related issues that diagnostics link to the module’s software.

Question 2

Do you offer mobile services, and how does the process work?

Accepted Answer

Yes! Flasher on Wheels is a fully mobile service. We come directly to your location—Atlanta, Jonesboro, East Point, Stockbridge, Hampton, Lovejoy, and surrounding areas—with professional dealership-level equipment. We also travel beyond these areas by request. Schedule an appointment, and we’ll complete the service onsite, saving you time and towing costs.

Question 3

What is ADAS calibration, and when should it be done?

Accepted Answer

ADAS (Advanced Driver Assistance Systems) calibration ensures cameras, sensors, and safety features like lane assist and collision warning work properly. It’s required after windshield replacements, suspension work, collisions, or any time sensors are moved or replaced.

Question 4

How long does module flashing and coding take?

Accepted Answer

Most services take 30 minutes to 4 hours, depending on the vehicle and how many modules need to be updated. We’ll provide an estimated timeframe before starting.

Question 5

What are vehicle software updates, and how do I know if I need one?

Accepted Answer

Vehicle software updates keep your car running smoothly by installing the latest manufacturer-released software. These updates can improve performance, fix bugs, and address recalls. We can scan your vehicle to check if updates are available.

Question 6

Can you perform advanced diagnostics on all makes and models?

Accepted Answer

Yes. We use factory-level diagnostic tools for Domestic, European, and Asian vehicles. Our diagnostics pinpoint electrical or software issues and come with a detailed report of recommended solutions.

Question 7

Do I need to go to the dealership for these services?

Accepted Answer

No! Flasher on Wheels provides dealership-level programming, coding, and diagnostics right at your location, saving you time and money.

Question 8

How much do your services cost?

Accepted Answer

Pricing varies depending on the vehicle and the service needed. We offer upfront, transparent quotes before starting any work, so you’ll never be surprised by the cost.

Question 9

What if I pay for a programming service and it doesn’t fix my vehicle? Do I still have to pay?

Accepted Answer

Yes, payment is still required for the programming service. We will provide confirmation that the updates were completed successfully. If the issue persists, it may be due to another underlying problem that requires advanced diagnostics. Diagnostic services are separate and not included in the programming fee. For best results, we recommend scheduling a diagnostic service before proceeding with programming.
