A computer system called OBD II (On-Board Diagnostics-Second Generation) monitors the operation of the vehicle to ensure emissions are at acceptable levels, helping to maintain a clean environment. The malfunction indicator lamp comes on when the vehicle is placed in ON/RUN, as a check to show it is working. If it does not, have the vehicle serviced by your dealer. See Ignition Positions on page 9-15.
If the malfunction indicator lamp comes on while the engine is running, this indicates that the OBD II system has detected a problem and diagnosis and service might be required.
Malfunctions often are indicated by the system before any problem is apparent. Being aware of the light can prevent more serious damage to the vehicle. This system also assists the service technician in correctly diagnosing any malfunction.
Caution
Modifications to these systems could lead to costly repairs not covered by the vehicle warranty. This could also result in a failure to pass a required Emission Inspection/Maintenance test. See Accessories and Modifications on page 10-2.
This light comes on during a malfunction in one of two ways: Light Flashing: A misfire condition has been detected. A misfire increases vehicle emissions and could damage the emission control system on the vehicle. Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
If the light continues to flash, find a safe place to stop and park the vehicle. Turn the vehicle off, wait at least 10 seconds, and restart the engine. If the light is still flashing, follow the previous steps and see your dealer for service as soon as possible.
Light On Steady: An emission control system malfunction has been detected on the vehicle.
Diagnosis and service might be required.
The following may correct an emission control system malfunction:
A few driving trips with the cap properly installed should turn the light off.
These conditions might go away once the engine is warmed up.
If one or more of these conditions occurs, change the fuel brand used.
It may require at least one full tank of the proper fuel to turn the light off.
See Recommended Fuel on page 9-36.
If none of the above have made the light turn off, your dealer can check the vehicle. The dealer has the proper test equipment and diagnostic tools to fix any mechanical or electrical problems that might have developed.
Emissions Inspection and Maintenance Programs
Depending on where you live, your vehicle may be required to participate in an emission control system inspection and maintenance program. For the inspection, the emission system test equipment will likely connect to the vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to the left of the steering wheel. See your dealer if assistance is needed.
The vehicle may not pass inspection if:
If this has been done and the vehicle still does not pass the inspection for lack of OBD II system readiness, your dealer can prepare the vehicle for inspection.
The Malfunction Indicator Lamp, also known as the Check Engine Light, plays a vital role in the Chevrolet Captiva First Generation, alerting drivers to potential issues within the engine or emissions system. Its illumination on the dashboard serves as a warning for drivers to address underlying problems promptly to ensure optimal vehicle performance and prevent further damage.
The MIL can be triggered by various factors, including engine misfires, faulty oxygen sensors, problems with the emissions control system, or other engine-related issues. When the light turns on, the vehicle's onboard diagnostic system (OBD-II) stores a corresponding trouble code, which can be accessed using a diagnostic scanner.
Retrieving the trouble code provides valuable information about the specific problem affecting the vehicle. It's important to note that while the MIL indicates a problem, not every instance signals a severe issue; sometimes, it could be a minor concern like a loose gas cap that needs tightening.
Dealing with the MIL in the 2018 Chevrolet Captiva typically involves several steps. First, drivers should check the gas cap to ensure it's securely fastened to prevent fuel vapor leakage, a common trigger for the MIL. Next, using a diagnostic scanner to read and interpret the trouble codes helps diagnose the root cause accurately.
Once the problem is identified, it's essential to diagnose and repair the underlying issue promptly. This may involve replacing or repairing faulty components related to the trouble code. After resolving the problem, clearing the trouble codes using the diagnostic scanner resets the MIL. If the issue is successfully addressed, the light should turn off, indicating that the problem has been resolved.
If the MIL persists or the vehicle exhibits abnormal symptoms such as rough idling, reduced power, or unusual noises, seeking professional assistance from a qualified mechanic or dealership is recommended. Ignoring the MIL can lead to more significant issues and potential repercussions on vehicle performance and emissions compliance.
