2019-chevrolet-cruze-auto-start-stop-eliminator

This inline memory harness is for the 2019 Chevrolet Cruze. It stores the last stop-start setting you chose, so if you turned Auto Stop/Start off on one drive, it stays off the next time you start the engine. 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.

Fitment

Listed applications (each row is a 100% fitment match for the factory connector this part uses):

• Chevrolet Cruze: 2019

For reference, the Chevrolet Cruze in these years is a compact sedan offered with 1.4L turbo four-cylinder engines, with a 1.6L turbo-diesel offered on 2017-2019 models. The listing is written around the second-generation (2016-2019) Cruze. Trim levels are not split out in the table, so confirm that your vehicle has the stop-start button before ordering.

What the factory system does

On the Chevrolet Cruze, Auto Stop/Start shuts the engine down at a stop and fires it back up as the brake is released. You can switch it off with the dash button, but the choice is not saved. The next ignition cycle brings the default back. The module keeps the choice you made instead.

Connecting it

It plugs in line with the factory connector named in the instructions. Both ends are factory-style plugs, so nothing is cut or spliced. Disconnect nothing else and splice nothing. Once both plugs are locked, tuck the harness where it will not be pinched when the panel goes back on. Test by switching Auto Stop/Start off, cycling the ignition and checking the indicator.

Typical reasons to keep it off

Stop-start saves the most fuel in long idles, but plenty of drivers would rather keep the engine running. Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap. On a compact sedan, any of these can mean a button press at the start of nearly every drive.

Battery notes for stop-start vehicles

If the stop-start indicator shows the system as unavailable, test the battery before anything else. On stop-start vehicles that is the most common cause. A replacement should match the original specification (AGM or EFB), and some manufacturers call for a battery monitor reset after the swap.

Diagnostics first

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.

What changes after installation

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

If stop-start is not engaging

A Chevrolet Cruze 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.

Check before you order

• Model year and model match a row in the table above (2019 Chevrolet Cruze).
• Your Chevrolet Cruze 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.
• The battery and charging system test good and no warning lights are on.
• No aftermarket remote start, alarm or gateway bypass is wired into the same circuit. If one is, email support before ordering.
• If you are unsure, send your VIN to support@automotivebypass.com and we will confirm fitment.

Warranty and returns

You have 45 days to request a return (pre-approval required, 20% restocking fee, buyer-paid return shipping). The module is backed by a 3-year limited warranty.
