How to Reset the TPMS on Your Daewoo Vehicle
If the tire pressure monitoring system (TPMS) light has come on in your Daewoo vehicle, it means that one or more of your tires has low air pressure. It’s important to properly inflate the tires and reset the TPMS to turn off the warning light. In this comprehensive guide, we’ll walk through the steps to reset the TPMS on various Daewoo models using both manual relearn procedures and an OBD scanner. We’ll also provide expert tips to ensure your tires stay properly inflated for optimal safety, performance, and fuel efficiency.
Which Daewoo Models Have TPMS?
Most recent Daewoo vehicles are equipped with a tire pressure monitoring system, as this has been required on all new passenger vehicles sold in the United States since 2007. Some of the popular Daewoo models that have TPMS include:
- Daewoo Lanos (1997-2002)
- Daewoo Nubira (1997-2002)
- Daewoo Leganza (1997-2002)
- Daewoo Matiz (1998-present)
- Daewoo Magnus (2000-2006)
- Daewoo Kalos (2002-2005)
- Daewoo Lacetti (2002-2008)
- Daewoo Tosca (2006-2011)
- Daewoo Gentra (2005-2011)
Even if your specific Daewoo model is not listed above, if it was made in 2007 or later, it almost certainly has TPMS. Check your owner’s manual to confirm and to determine what type of TPMS relearn procedure it requires.
Daewoo TPMS Reset Using Manual Relearn Method
Many Daewoo models allow you to reset the TPMS using a manual relearn procedure that involves putting the system into “learn mode” and then using a TPMS tool to activate each sensor. Here are the general steps:
- Ensure all tires are inflated to the pressure listed on the door jamb placard.
- Turn the ignition to the “On” position but do not start the engine.
- Press and hold the TPMS reset button (often located under the steering wheel) until the TPMS light blinks three times. This puts the system in learn mode.
- Starting with the left front tire, use a TPMS tool to activate the sensor by holding it against the sidewall near the valve stem. The horn will chirp to confirm it has been recognized.
- Repeat the process for the other three tires in this order: right front, right rear, left rear. The horn will chirp twice to confirm the relearn is complete.
- Turn the ignition off and then start the vehicle. The TPMS light should now be off. If it remains on, repeat the relearn procedure or see the section on troubleshooting below.
The exact procedure can vary between Daewoo models, so consult your owner’s manual for the specific steps for your vehicle. For example, on some older Daewoo models like the Lanos, you may need to use the key to turn the ignition on and off a certain number of times to initiate the relearn mode rather than pressing a dedicated TPMS reset button.
Resetting Daewoo TPMS with an OBD Scanner
Some newer Daewoo vehicles require an OBD relearn procedure to reset the TPMS after replacing or rotating tires. This method involves connecting a scan tool to the OBD-II port and inputting the sensor IDs so the system can relearn their positions. Here’s a general overview of the process:
- Ensure all tires are inflated to the proper pressure based on the placard on the door jamb.
- Connect your OBD scanner to the vehicle’s OBD-II port, which is usually located under the dashboard on the driver’s side.
- Turn the ignition to the “On” position but do not start the engine.
- Using your scan tool, navigate to the TPMS relearn function. This may be located under “Vehicle Information,” “Tire Pressure Monitor,” or similar, depending on your scanner.
- Select “Manual Relearn” or “OBD Relearn” if prompted.
- Activate each sensor with your TPMS tool in the order specified by your scanner, usually starting with the left front and going clockwise. The horn will typically honk to confirm each sensor.
- Once all sensor IDs have been entered, the scanner will send them to the TPMS module to complete the relearn process.
- Turn the ignition off, remove the scanner, and start the vehicle. The TPMS light should now be off, indicating a successful relearn. If the light remains on, see the troubleshooting tips below.
Consult your owner’s manual and scan tool instructions for the exact steps for your Daewoo model, as procedures can vary. For example, some 2008 and later Daewoo models require a “TPMS Relearn” command to be sent via the OBD-II port after sensor IDs are registered in order to complete the process.
Tips for Maintaining Proper Tire Pressure
Resetting the TPMS light is important, but it’s even more critical to ensure your tires are always properly inflated. Here are some tips to help maintain optimal tire pressure:
- Check tire pressure monthly. Tires can lose about 1 PSI per month naturally, so check all four tires and the spare at least once a month using a good quality tire pressure gauge.
- Check pressure when tires are cold. The best time to check tire pressure is early in the morning after the car has been parked overnight. Driving heats up the tires and increases pressure, so checking when cold provides the most accurate reading.
- Inflate tires to the manufacturer’s recommendations. The proper tire pressure for your Daewoo model is listed on a placard on the driver’s side door jamb. Do not use the “max pressure” number on the tire sidewall, as that is the tire’s maximum pressure rating, not the recommended pressure for the vehicle.
- Don’t rely solely on TPMS. The TPMS light is designed to alert you when tire pressure drops 25% below the recommended level. By this point, tires may already be underinflated enough to impact safety and fuel economy. Check tire pressure regularly even if the TPMS light is not on.
- Rotate tires regularly. Rotating tires every 5,000-8,000 miles helps ensure even tire wear. Just remember that a TPMS relearn procedure is usually required after rotation so the system can relearn the sensor positions.
Troubleshooting Daewoo TPMS Reset Issues
If you’ve followed the steps to reset your Daewoo’s TPMS but the light remains on, here are a few troubleshooting tips:
- Double check tire pressure. Use a trusted tire pressure gauge to confirm all tires are inflated to the proper PSI. If any tire is low, add air and attempt the relearn again.
- Ensure all tires have functioning TPMS sensors. If you’ve recently replaced one or more tires, make sure the new tires have compatible TPMS sensors installed. You can check this using your TPMS tool.
- Repeat the relearn procedure. It’s possible the relearn wasn’t successful on the first attempt. Try repeating the procedure, ensuring you follow each step correctly for your specific Daewoo model.
- Check for TPMS sensor battery issues. TPMS sensors have internal batteries that typically last 5-10 years. If a sensor’s battery is dead, it won’t transmit data and the relearn will fail. In this case, the faulty sensor will need to be replaced.
- Consult a professional. If you’re still having trouble resetting the TPMS, it’s best to have a tire professional or Daewoo dealership diagnose the issue. There could be a problem with the TPMS module, wiring, or other components that require specialized equipment to identify and fix.
The Importance of Proper Tire Pressure and TPMS Maintenance
Maintaining proper tire pressure is essential for several reasons:
- Safety: Underinflated tires can cause uneven wear, decreased traction, longer stopping distances, and increased risk of blowouts – all of which compromise vehicle control and safety.
- Fuel efficiency: Tires that are underinflated by just 5-7 PSI can decrease fuel economy by about 2%. Keeping tires properly inflated maximizes fuel efficiency.
- Tire life: Underinflation causes tires to wear unevenly and more rapidly, shortening their lifespan. Properinflation helps your tires last as long as possible.
The TPMS helps alert you when tire pressure has dropped significantly, but it’s not a substitute for regular tire pressure checks and maintenance. Resetting the TPMS is important to ensure the system can provide accurate warnings and prevent the annoying light from remaining on after tires have been inflated or replaced.
By following the steps outlined above for resetting the TPMS on your Daewoo model and keeping tires properly inflated, you can help ensure your vehicle’s safety, performance, efficiency, and longevity. If you have any doubts about the process or encounter issues, don’t hesitate to contact a tire professional or your local Daewoo dealership for expert assistance.
