Where is the Engine Control Module Located in a Chevrolet Cruze?

Snowflake Cruze engine control module is located to the right of the gear shift console. More information about the engine control module is as follows: 1. The Automobile Engine Control Module is the core component of engine control. Based on input from various sensors, it controls the engine's fuel injection and ignition timing, and provides optimal control commands to other output devices. 2. The Engine Control Module (ECM) interacts with many emission-related components and systems, monitoring them for any performance degradation. OBD-II diagnostics monitor system performance and set Diagnostic Trouble Codes (DTC) when performance declines.
I just fixed an engine issue on my friend's Cruze, and the location of the engine control module is indeed a bit hidden. On the Chevrolet Cruze, this thing is usually in the engine compartment, near the upper left corner of the firewall, especially in older models like the 2008-2015 versions. After opening the hood, look toward the battery—there's a black or gray plastic box secured with screws and surrounded by wiring connectors. If you can't find it, try removing the cover near the air filter housing; the ECM is hidden there. Remember to disconnect the negative battery terminal before touching it to avoid electric shock or short circuits, as the module is prone to throwing fault codes when disturbed. While working on the car, I also found that the location might vary by model year, sometimes moving under the dashboard near the passenger footwell, so it's best to check the manual or online repair diagrams. Don't attempt to disassemble it randomly—if you break the clips, you might end up spending unnecessary money at a professional shop to fix it.
As someone who frequently works on American cars, I've noticed the Chevrolet Cruze's engine control module is primarily installed near the firewall at the rear of the engine bay, potentially on either the driver or passenger side. The typical location is behind the area where the hood opens, close to the brake booster, appearing as a small black box nestled within the sound insulation pad. Before locating it, take photos with your phone to document the original layout, preventing assembly errors later. This design aims to protect the module from high temperatures and dust, though it tends to accumulate dust, leading to poor contact issues. I recommend regularly cleaning dust from the engine bay to prevent wire corrosion. For models newer than 2016, the module might have been relocated beneath the interior floor mats, requiring removal of carpet panels for access. Always ensure the engine is off and the battery is disconnected before handling it—safety comes first above all else.
