2024-2025 Chevrolet Trax Auto Start Stop Eliminator

A inline memory harness for the 2024–2025 Chevrolet Trax. Out of the factory, Auto Stop/Start comes back on at every key cycle. This module remembers your last choice and sends it again at the next start. It plugs in line with the factory connector named in the instructions. Both ends are factory-style plugs, so nothing is cut or spliced.

Nothing is reprogrammed in the engine computer. The module only stands in for the button press you would otherwise make after every start, and it comes out without leaving a trace.

Which Chevrolet Trax models it fits

The fitment table for this SKU lists the following, each marked as a 100% fitment match:

• Chevrolet Trax: 2024–2025

For reference, the Chevrolet Trax in these years is a subcompact crossover offered with 1.2L turbo three-cylinder engines. The listing is written around the second-generation (2024-up) Trax. Trim is not listed separately. Any trim in these years with factory stop-start and the pictured connector is covered.

Why the button resets

Auto Stop/Start is designed to default to on. The off switch (usually marked with an "A" inside a circular arrow) cancels it for the current drive. At the next start the system is armed again. That reset is intentional on the manufacturer's side, and it is the only behavior this module changes.

What to expect

• Leaves no permanent change after removal.
• Holds the stop-start button state between drives.
• Leaves engine and transmission software untouched.
• Lets you re-enable the system with the factory button at any time.

If stop-start is not engaging

A Chevrolet Trax that rarely auto-stops is often telling you something about the battery. Stop-start vehicles usually run an AGM or EFB battery, and the system is one of the first features to drop out as that battery ages. Cabin temperature requests, engine temperature and brake pressure also factor in. None of these checks are altered by the module.

Battery and charging

Vehicles with stop-start normally use an AGM or EFB battery sized for repeated restarts. If you replace it, use the same type and size, and follow the manufacturer's battery reset or registration step where one exists. A wrong or unregistered battery can leave the stop-start system disabled, and that has nothing to do with this module.

Where it connects

It plugs in line with the factory connector named in the instructions. Both ends are factory-style plugs, so nothing is cut or spliced. Work with the ignition off. Seat each connector until its lock engages, then secure the module with the supplied ties or tape so it cannot rattle or touch pedals, steering parts or anything hot. Start the vehicle, press the stop-start button once, then restart to confirm the choice is held.

Why owners turn it off

Pressing the same button on every drive is what wears on owners. People who tow, plow, idle in pickup lines, creep through heavy traffic or simply want the engine running at a light end up making the same press dozens of times a week. On the Chevrolet Trax, the module turns that into a one-time choice you can still change whenever you want.

If something does not look right

If the setting is not remembered, check that the module was installed with the ignition off and that the connector clicked into place. Then press the factory button once, switch the vehicle off, close the doors, give the electronics time to shut down, and start again. If it still resets, contact support with the year, trim and a photo of the connector.

Fitment check

• Model year and model match a row in the table above (2024–2025 Chevrolet Trax).
• Your Chevrolet Trax has the factory stop-start button. Base trims or engines without stop-start have nothing for the module to remember.
• The connector at your install point matches the one in the product photos.
• No aftermarket remote start, alarm or gateway bypass is wired into the same circuit. If one is, email support before ordering.
• The battery and charging system test good and no warning lights are on.
• If you are unsure, send your VIN to support@automotivebypass.com and we will confirm fitment.
