How To Turn Off Auto Stop On 2019 Chevy Equinox
The engine auto-stop feature on the 2019 Chevy Equinox shuts off the vehicle when coming to a complete stop to conserve fuel, but it can be temporarily disabled using the dashboard button or permanently bypassed using an aftermarket auto-stop eliminator harness. This comprehensive guide outlines the factory temporary method, permanent hardware solutions, technical mechanics, and troubleshooting protocols required to manage the system effectively.
Understanding Your Vehicle's Automatic Stop-Start System
Before making modifications to your 2019 Chevrolet Equinox, understanding how the powertrain control module manages the stop-start (A/S/S) system ensures safe and reliable vehicle operation. The system is designed to reduce tailpipe emissions and improve fuel economy during city driving by killing the engine when the brake pedal is depressed and restarting it the moment the pedal is released. However, frequent engine cycling increases wear on the starter motor, auxiliary battery, and ignition components, leading many drivers to seek methods to disable it.
Implementing a modification requires careful planning and the right tools if you choose a permanent bypass method. Review the operational criteria below to determine the best approach for your driving habits.
- Essential Gear & Tools: Standard trim removal tools, flashlight, 10mm socket wrench (if accessing battery-mounted systems), and a dedicated plug-and-play auto-stop eliminator harness.
- Mandatory Prerequisite Knowledge: Familiarity with automotive interior trim panel removal, basic wire harness manipulation, and an understanding of the 12V auxiliary battery management system.
- Estimated Time & Budget: 5 minutes for temporary dash button disabling; 20 to 30 minutes for a permanent hardware harness installation; $0 for factory methods or $30 to $100 for plug-and-play modules.
Step-by-Step Guide to Disabling the Stop-Start Feature
Depending on your preference for a temporary workaround every time you drive or a permanent installation that remembers your settings, follow the specific execution steps below to stop your 2019 Equinox engine from shutting off at red lights.
Step 1: Using the Factory Dashboard Disable Button
- Locate the designated auto-stop disable switch on the center console or instrument panel of your 2019 Chevy Equinox, typically marked with an "A" encircled by an arrow next to an "OFF" label.
- Start the engine using the push-button ignition or physical key.
- Press the auto-stop off button immediately after the vehicle enters run mode; an indicator light on the button or a message in the driver information center will illuminate to confirm the system has been temporarily deactivated.
- Note that this factory method only disables the system for the current ignition cycle; when you turn the vehicle off and back on, the auto-stop feature resets to active.
Warning: Never attempt to alter factory wiring harnesses while the ignition is in the ON position or while the vehicle is running, as this can trigger Diagnostic Trouble Codes (DTCs) in the Powertrain Control Module (PCM) and Body Control Module (BCM).
Step 2: Installing a Permanent Auto-Stop Eliminator Harness
- Purchase a model-specific, plug-and-play auto-stop eliminator harness designed specifically for the 2019 Chevrolet Equinox architecture.
- Disconnect the negative battery terminal using a 10mm socket wrench to prevent electrical shorts or triggering airbag warning lights during interior disassembly.
- Use a non-marring plastic trim removal tool to carefully pry away the center console or switch bank housing surrounding the hood release or shift console, depending on where your specific harness intercepts the switch signal.
- Unplug the factory wire connector from the rear of the auto-stop disable switch.
- Plug the aftermarket eliminator harness in-line between the factory switch and the factory wiring plug, ensuring the locking tabs click securely into place.
- Tuck the small control module of the eliminator securely behind the dash panel away from moving parts, gear selectors, or heating vents, then reassemble the interior trim panels.
- Reconnect the negative battery terminal, start the vehicle, and verify that the system automatically toggles to the "OFF" state a few seconds after ignition startup.
Pro-Tip: Route any aftermarket wiring modules away from the steering column intermediate shaft and heater core lines using zip ties to eliminate rattles and prevent thermal degradation.

Common System Behaviors and Troubleshooting Fixes
Modifying or managing the auto-stop system on a 2019 Chevy Equinox can occasionally surface unique electrical or operational anomalies. Review these common scenarios to diagnose and resolve issues efficiently.
- Symptom: The plug-and-play eliminator module fails to automatically turn off the system upon startup.
- Root Cause: The harness data-bus loop was not seated correctly or lost power continuity during vehicle boot-up.
- Actionable Fix: Disconnect the negative battery terminal for 10 minutes to hard-reset the body control modules, verify all pin connections on the inline harness, and retest.
- Symptom: Check Engine Light (CEL) appears after altering wiring or disconnecting battery components.
- Root Cause: Temporary communication loss between the PCM and the BCM triggered a soft diagnostic code.
- Actionable Fix: Scan the vehicle using an OBD2 diagnostic tool to clear historical codes, or drive the vehicle through two complete drive cycles to allow self-clearing.
- Symptom: The vehicle auto-stops even when the AC is running heavily.
- Root Cause: Cabin temperature demands have been satisfied, allowing the climate control compressor to cycle down and permit auto-stop functionality.
- Actionable Fix: Adjust the climate control system to maximum defrost or low fan speeds, or utilize the manual override button to prevent unexpected shutdowns.
Frequently Asked Questions
Will turning off the auto-stop void my factory warranty?
Using the factory dashboard button will never void your warranty. However, installing aftermarket wiring harnesses or altering factory computer programming may be subject to scrutiny under the Magnuson-Moss Warranty Act if the specific modification can be proven to have directly caused a mechanical or electrical failure.
Does turning off auto-stop affect my fuel economy?
In real-world driving conditions, disabling the auto-stop feature results in a negligible decrease in fuel efficiency, typically amounting to less than a half-mile per gallon loss. The actual variance depends heavily on your frequency of stop-and-go city commuting versus highway driving.
Why does my 2019 Equinox auto-stop even when I press the button?
If the system engages despite pressing the button, the button may be faulty, the vehicle may be in a specific diagnostic mode, or an aftermarket module was installed incorrectly. Verify that the indicator light on the switch illuminates immediately upon pressing it during an active ignition cycle.
Can I disable auto-stop by unplugging the hood latch sensor?
While unplugging the hood latch sensor tricks the vehicle computer into thinking the hood is open (which prevents auto-stop as a safety precaution), it is not recommended. Doing so will disable remote start functionality and trigger a constant warning message on your driver information center.
Does the 2019 Equinox have a fuse for the auto-stop system?
Chevrolet does not provide a dedicated, standalone fuse solely for the auto-stop feature. The auto-stop algorithm is integrated deep within the software programming of the Powertrain Control Module and relies on inputs from the brake pressure sensor, battery voltage monitor, and wheel speed sensors.
