How to Reset the Wrench Light on a Car?
4 Answers
Insert the key, but only insert it without turning. Hold down the trip meter button for 5-10 seconds, then turn the key to the "ON" position. After another 5-10 seconds, start the engine. Keep holding the button throughout this process without releasing it. The wrench indicator will then be reset.
That wrench symbol lighting up on the dashboard means it's time for vehicle maintenance. Last time I encountered this, the technician at the 4S shop helped clear it after servicing - they just plugged in a computer diagnostic tool and fixed it in minutes. Actually, this indicator is like an internal reminder system preset by the vehicle, automatically alerting when reaching scheduled maintenance mileage. For DIY reset: first turn off and disconnect power, then press and hold the trip reset button on the dashboard while turning the key to power-on position (without starting the engine), release the button when the wrench light flashes. Note reset procedures vary significantly between models - Japanese and American cars use completely different methods. If unsuccessful, consult professionals who can also verify critical maintenance items like oil and brakes are properly serviced.
That wrench light coming on is most likely reminding you to get your vehicle serviced. Having run an auto repair shop for over a decade, I often get customers asking about this. The reset method actually varies by make and model. For German cars like Volkswagen, turn off the ignition, hold down the trip reset button on the dashboard, then turn the key to ON position and maintain for 3 seconds. Nissan models require simultaneously pressing the brake, accelerator and reset button. The Hyundai Tucson is even more unique - you need to long-press the steering wheel button with the engine running. I recommend owners first check their vehicle's owner's manual, which usually contains detailed reset procedures. If the manual is lost, search online for tutorial videos specific to your model. If all else fails, take it to a repair shop where technicians can reset it using diagnostic equipment while performing all necessary maintenance items in one go.
Don't panic when you see the wrench light on your dashboard—it's mainly a reminder for vehicle maintenance. Last time my car's light came on because I forgot to change the oil on time. Nowadays, many cars have simple reset methods: turn off the engine, press and hold the TRIP button on the dashboard, then turn the key to the ignition position without starting the engine, and hold for about 5 seconds until the indicator light flashes and disappears. However, some high-end models require a professional OBD diagnostic tool to reset the maintenance counter, making it more complicated to do it yourself. It's best to have the mechanic reset the indicator light immediately after each maintenance service to avoid any confusion. Regular maintenance is truly important—not only does it clear the wrench light, but it also ensures driving safety.
