Silverado / Sierra / Tahoe / Suburban / Yukon Custom BCM Programming (2014–2020 K2)

Description

Custom BCM programming for your K2 truck or SUV. We program the body control module (BCM) from your 2014-2019 Silverado or Sierra, 2015-2020 Tahoe, Suburban, Yukon or Escalade, or 2019-2025 Silverado medium duty, with the features you choose. One price covers every feature on this page. You remove your BCM and ship it in, we build the calibration from your vehicle’s own factory software, change only what you ordered, and send it back ready to plug in. There’s no programmer to buy and nothing to flash yourself.

How it works

1. Choose your features and enter your 17-digit VIN. The VIN is required, so have it ready before you start.
2. Check out. Return shipping for your BCM is calculated at checkout from your address.
3. Remove your BCM and ship it to us using the instructions in your order confirmation.
4. We confirm the VIN, build your calibration from your vehicle’s factory file, and program your BCM.
5. We ship it back plug and play. Reinstall it and your features are ready to use.

We keep your original calibration on file, so any change can go back to stock.

One price, any features

The programming fee covers every feature below. Choose as many or as few as you want. Each one costs nothing extra.

Features

Lighting Features

• Cargo/Bed Lamps While Driving (pickups only)
  The cargo and bed lamps stay on, and can be switched on, in Drive or Reverse. From the factory they shut off once you leave Park.
• Fog Lights with High Beams
  Your fog lights stay on when you switch to high beams. From the factory they turn off.
• Fog Lights with Auto High Beams (IntelliBeam) (requires factory IntelliBeam)
  Your fog lights stay on while IntelliBeam is switching the high beams automatically.
• Hyperflash Delete (for LED Bulbs)
  Stops the fast flash and bulb-out warning after you install LED turn signal bulbs. This also removes the warning for a burned-out turn signal bulb, so you’ll need to check your turn signals yourself.
• Market Lighting Conversion (imported vehicles)
  For vehicles imported from another country. Choose Convert to US Market to set a Canadian-market vehicle’s lighting, including daytime running light behavior, to US factory settings. Convert to Canadian Market does the reverse for a US vehicle going to Canada.

Convenience Features

• Roll Up Windows from Key Fob (express-up windows only)
  Hold Lock on the key fob to roll up the front windows that have express-up (one-touch up). If only the driver’s window has express-up, only that window rolls up. The rear windows don’t roll up from the fob.
• Remote Start Runs for 20 Minutes per Cycle (requires factory remote start)
  Each remote start runs for 20 minutes instead of the factory 15.
• Cooled Seats with Remote Start (requires factory ventilated seats)
  Adds the cooled seat option to your remote start settings menu.
• Disable Auto Idle Shutdown (push-button start vehicles)
  The engine no longer shuts itself off after idling in Park for a while.
• Raise the Speed Limiter
  Choose 112 or 120 mph. This raises the limit set in the BCM only. The engine computer may still limit top speed, and your tires must be rated for the speed you choose.

More Settings

• Light and Window Timers
  Sets how long lights stay on and windows keep working after you shut the vehicle off. Factory: no change. Extended: cargo and bed lamps shut off after 60 minutes, headlights and interior lights left on shut off after 20 minutes, and windows keep working for 20 minutes. Maximum: 120 minutes for cargo and bed lamps, 30 minutes for headlights and interior lights, and 40 minutes for windows. Longer timers mean lights left on can drain the battery further before they shut off.
• Tap-to-Pass Flashes
  Sets how many times the turn signal flashes when you tap the stalk for a lane change: 3 (factory), 4 or 5. Applies in normal driving. Tow/Haul mode keeps its own factory count.

Activate GM Retrofit Parts

Added GM parts from a higher trim? Most of them won’t work until the BCM is programmed for them, and these switch them on. We don’t supply or install the parts. They must already be installed and wired.

• Fog Lights
  Turns on fog lights added to a trim that didn’t come with them. Some vehicles also need the instrument cluster programmed to show the fog light indicator. That’s separate from this BCM service, so contact us if yours needs it.
• Heated Front Seats
  Turns on heated front seats added to a vehicle that didn’t come with them.
• Ventilated Front Seats
  Turns on ventilated (cooled) front seats.
• Heated Rear Seats
  Turns on heated rear seats.

Frequently asked questions

Does each feature cost extra?

No. One programming fee covers every feature you choose, whether you pick one or all of them. The only other charge is return shipping for your BCM, which is calculated at checkout from your address.

Do I need to buy a programmer or tool?

No. You remove your BCM and ship it to us. We program it here and send it back ready to plug in. You don’t buy, register or plug in any device.

Can I buy a BCM from you with these features already programmed?

No. Your vehicle’s BCM holds data that belongs to that vehicle, including its security and key data and its mileage record. A different BCM wouldn’t have any of that, so it wouldn’t work properly. That’s why we program the BCM you already have and send it back to you.

Do I need my VIN to order?

Yes. Your 17-digit VIN is required before you can add this to your cart, because the calibration is built for your vehicle. You’ll find it on the driver’s side of the dashboard where it meets the windshield, on your registration, or on your insurance card.

Which vehicles does this fit?

2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500, the 2019 Silverado LD and Sierra Limited, 2015-2019 Silverado and Sierra 2500HD and 3500HD, 2019-2025 Silverado 4500HD, 5500HD and 6500HD, and 2015-2020 Chevrolet Tahoe and Suburban, GMC Yukon and Yukon XL, and Cadillac Escalade and Escalade ESV. These are GM’s K2 trucks and SUVs. We check every VIN before we program anything.

Is my 2019 Silverado or Sierra covered here?

If it’s a 2019 Silverado LD or Sierra Limited, or a 2019 2500HD or 3500HD, yes. Those carry over the previous body and use this programming. The redesigned 2019 Silverado and Sierra 1500 is covered by our 2019-2022 Silverado and Sierra BCM programming instead. Enter your VIN and it will tell you which one you need.

What does the BCM control on a 2014-2018 Silverado?

The body control module runs most of the truck’s body electronics: exterior and interior lighting, turn signals, door locks and key fob functions, power windows, remote start, the alarm and many warning chimes. That’s why lighting, remote start and key fob behavior can be changed by programming the BCM.

Does it work on Tahoe, Suburban, Yukon and Escalade?

Yes. 2015-2020 Tahoe, Suburban, Yukon, Yukon XL, Escalade and Escalade ESV are covered. Features that depend on a pickup bed, such as Cargo/Bed Lamps While Driving, only apply to pickups.

Do you program medium duty Silverado trucks?

Yes. 2019-2025 Silverado 4500HD, 5500HD and 6500HD trucks are covered. Equipment varies a lot on these trucks, so we confirm which features apply to yours from your VIN before we build anything.

Can I order for two vehicles at once?

Each order is built for one VIN, so place a separate order for each vehicle.

Will it set trouble codes?

Not for the lighting, convenience and settings features. Retrofit part activations turn on GM’s own fault monitoring for those parts, so the parts must be installed and wired. With the parts in place, the vehicle behaves like one that came with them from the factory. Without them, expect codes.

Can it go back to stock?

Yes. We keep your vehicle’s original calibration on file, so any change can be put back to factory.

My truck was imported from Canada. Can you change the lighting to US spec?

Yes. Choose Market Lighting Conversion and select Convert to US Market. We set the lighting, including daytime running light behavior, to US factory settings. A US vehicle going to Canada can be set to Canadian settings the same way.

Why don’t you offer more remote start time or manual high idle?

Both also need changes to the engine computer. This service programs the body control module only, so remote start tops out at 20 minutes per cycle and manual high idle isn’t offered.

Does raising the speed limiter remove every speed limit?

No. It raises the limit set in the BCM to the speed you choose. The engine computer may still apply its own limit. Your tires must be rated for the speed you select.
