Tire pressure monitoring systems (TPMS) might be small, but they play a big role in your customer’s vehicle safety. That’s why they demand attention at every step of the service process. Between diagnosing sensor issues to properly breaking the bead, what may seem like minor details in the service process can lead to comebacks, broken parts, or misdiagnosed problems. That’s why you and your technicians should look at TPMS service as more than just getting rid of the light on the dash. These TPMS tips can help ensure proper service and prevent costly mistakes.
Watch for Sensor and Signal Issues
If you’re working on issues with direct TPMS systems, you may deal with issues like a bad sensor or a dead battery. Regardless of the issue with the direct TPMS system, it’s important to test all sensors before performing any work – a.k.a. test before you touch.
Still dealing with issues after servicing direct TPMS? You may need to check out your scan tool. If the software isn’t updated, you may run into issues with sensor communication or functionality. Make sure your diagnostic tools are up to date. It can make a major difference in how effective your diagnostics are.
If you’re running into an issue that doesn’t seem sensor-related, the electronics inside the vehicle may be the cause. Improperly installed audio systems, car chargers, or video equipment can interfere with the radio signals TPMS sensors pick up. Signal interference can be easy to overlook, but it could be the hidden cause of erratic direct TPMS behavior.
TPMS Tips to Avoid Valve Damage
Breaking a TPMS valve during tire removal or installation is a mistake that even experienced techs can make. The key to avoiding TPMS sensor damage when removing or replacing a tire comes down to positioning.
When removing the tire, place the TPMS valve right before the traction point before pulling the bead over the rim (at about the 12 o’clock position). When reinstalling the tire, rotate the valve stem to the 6 o’clock position before starting. These techniques keep the valve from being in the way of your mounting tool, avoiding damage completely.
TPMS Doesn’t Replace Pressure Checks
Some customers may assume that because they have TPMS, they don’t have to manually check tire pressure. That’s just not the case. Following any service appointment, it’s up to you to tell customers why it’s still essential to maintain tire inflation specified on the door jamb. For shops, checking tire pressure should be part of both inspection and diagnostics – regardless of the service.
Low tire pressure without a TPMS light could be the sign of a failing sensor. That’s why it’s important to tell customers to regularly check tire pressure and to call you if low pressure is common, even without the TPMS light on.
TPMS Tips for Sensor Customization
These days, customers are looking to trick out and customize their vehicles more than ever. They may even request a sensor color that matches their custom wheels. If that’s the case, check out the Autel MX1 sensor. Autel offers it in aluminum, black, or chrome color options to meet those requests.
You can also offer customers a rubber valve option of the MX1 sensor. It can be changed with just the press of a button!
In your shop, TPMS service should include more effort than just swapping parts and getting rid of that pesky dashboard light. Use the tips to make sure your technicians are taking every step they can to avoid unnecessary TPMS service headaches.
