Chevrolet Colorado Mileage Blocker
The Chevrolet Colorado Mileage Blocker (2015–present) is a vehicle-specific plug-in module that connects behind the instrument cluster without cutting, soldering, or coding. It offers two selectable modes. In its active mode, mileage recording is stopped completely; a final mode returns the vehicle to normal operation. The speedometer reads correctly in all modes. After removal, use of the device is not detectable through diagnostics.
Prices for this vehicle range from £299.00 to £999.00 depending on your generation and device version. Select your vehicle below to see the exact price.

DHL & FedEx tracked shipping12 months warranty30-day returnsKey features
- Vehicle-specific wiring harness — built for the Chevrolet Colorado's exact connector layout; where possible we use OEM-style connectors for a factory-quality fit.
- Plug & Play installation — no cutting, soldering, or coding required; connects behind the instrument cluster in minutes.
- Complete mileage stop in active mode — mileage recording is stopped entirely while the device is active; the speedometer continues to read correctly.
- Fully removable — remove cleanly at any time; no mileage catch-up occurs and use is not detectable through diagnostics after removal.
- Persistent mode memory — the active mode is retained between ignition cycles; no need to reactivate each time.
- Control during testing — the device can be activated and deactivated while stationary or in motion during permitted off-road testing, giving full flexibility over when mileage recording is paused.
Operation & Functional Modes

How it works
Every modern vehicle uses a CAN-bus network — a high-speed digital communication system that links the engine control unit, instrument cluster, gearbox, ABS, and dozens of other modules. Distance data travels across this network continuously, and the instrument cluster reads those signals to update the odometer.
The Chevrolet Colorado Mileage Blocker installs in-line on the specific CAN-bus line that carries distance pulses toward the instrument cluster. It intercepts those signals at the wiring level — before they reach the cluster — and, depending on the selected operating mode, suppresses them entirely or reduces them to a set percentage.
The device uses vehicle-specific, original-type connectors and fits entirely within the existing wiring loom. No wires are cut, no soldering is required, and no coding or software changes are made to the vehicle. Removing the device restores the vehicle to its exact factory state.
Because the device operates at the physical wiring layer — not through the OBD-II port or any software interface — its presence cannot be detected by standard diagnostic equipment. It leaves no trace in the vehicle's fault memory. The device retains the last selected mode between ignition cycles.
Vehicle behaviour notes
Check engine light — 3rd Gen (8-port BCM, 2023–present): The check-engine light may illuminate while the mileage blocker is in use. Remote start is unavailable. The warning does not affect engine performance. Clearing stored fault codes after removal is recommended.
Optional OBD2 automatic eraser
The optional OBD2 automatic eraser is a compact dongle that plugs into the vehicle's OBD2 diagnostic port. While connected, it automatically clears certain stored diagnostic trouble codes (DTCs) during the ignition cycle. On supported vehicles, this can help restore remote functions that may otherwise be disabled by fault codes associated with mileage-blocker use.
It does not prevent or remove the check-engine light while the mileage blocker is in use. It clears codes; it does not repair an underlying fault. The remote functions restored depend on the vehicle and selected version.
Important information
This product is designed for off-road, motorsport, dyno testing and vehicle development use. It should not be used to alter the recorded mileage of any vehicle being offered for sale. Please ensure your use is in accordance with the laws that apply in your country.
