How to Cancel The Check Engine Light on a Suzukiby Patrick Warren
Since 1996, all Suzukis come with a diagnostic computer system that monitors the engine, transmission and other components for problems. The diagnostic computer system alerts the driver when a problem is found with the car via a check engine light. The diagnostic computer system has a data link connector. An OBD II reader is connected to the connector to retrieve the error codes that the diagnostic computer system provides. The OBD II reader also can be used to clear the error codes, canceling the check engine light.
Locate the data link connector on the Suzuki. Its location will vary, but usually is located under the dash, below the steering wheel. The exact location on each Suzuki, usually with a picture, can be found on the DLC locator link under Resources.
Turn the Suzuki ignition key to the "On" position. You do not need to start the vehicle, but turning the key to the "On" position powers the diagnostic computer system.
Plug the OBD II reader's connector into the Suzuki's DLC. If required by the reader model, power on the OBD II reader.
Follow the instructions provided with the OBD II reader to erase existing error codes and reset the diagnostic computer system. There are varying methods of doing this, including pressing an "Erase Codes" button or going through a specific menu option. The process will clear any error codes, resetting the diagnostic computer system. This cancels the check engine light.
Turn the Suzuki ignition key to the "Off" position. This powers down the diagnostic computer system to complete the reset. Start the Suzuki and verify that the check engine light is no longer lit. If the check engine light is still on, repeat the above steps. If the check engine light is still on after repeating the steps, this indicates a problem with the system diagnostic controller.
- Many auto parts stores and shops will plug their OBD II readers into your car, provide you the error codes, and clear the codes at no charge.
