Buick Enclave Mileage Blocker

About the Buick Enclave Mileage Blocker

The Buick Enclave Mileage Blocker is a plug-in CAN-bus module made specifically for the Buick Enclave (2024-2027). It fits in-line on the wiring behind the instrument cluster using connectors that match the factory loom, so there is no cutting, splicing, soldering or software coding. With the module active, the distance signal reaching the cluster is paused or reduced according to the mode you select; the speedometer and everything else on the dash keep working as normal.

Because it works at the wiring level rather than through the OBD port, it does not write anything to the car’s memory, and can be unplugged at any time to return the vehicle to standard. It is intended for dyno sessions, remapping and testing, track and off-road use, and vehicle development.

Enclave note: on this model the check engine light may come on while the module is active, and remote start may be temporarily unavailable. Driving and engine performance are not affected, and it clears once the module is switched to pass-through or removed. The optional OBD2 / DTC eraser clears stored codes automatically.

Options

• OBD2 / DTC eraser (+$375) – optional companion unit that automatically clears stored fault codes.

Operating modes

1. Mode 1 – Odometer paused – no distance is recorded while the module is active. Speedometer reads normally.
2. Mode 2 – Pass-through – the car records mileage and shows speed exactly as standard.

How to change mode: Flash the high beams 4 times in quick succession.
