The Trainer #71 - The 411 On TPMS

TPMS, or Tire Pressure Monitoring Systems, have been mandatory equipment on cars and light trucks for the last decade. Even so, how many times have you had a customer return after a routine service or repair that required tire/wheel removal with a now illuminated TPMS warning light? Recently, I had a similar situation hit home. My wife’s 2014 Scion Tc suddenly turned on the warning indicator. And it wasn’t the first time this has happened. In every other instance, a quick check revealed a punctured tire. Not this time. A check of the tire pressures found them all in specification! A check of the sensors themselves revealed no faulty components and no trouble codes related to the system were stored in the controlling module. So why was the light on? Both scenarios require the servicing technician to have a foundational knowledge of how TPMS works to resolve. In this edition of “The Trainer”, I’ll go over the fundamentals of the indirect and direct TPMS system functions and talk a bit about how to test both. More importantly, I’ll share tips on what to do before and after any service that could impact the TPMS system operation in order to avoid unnecessary comebacks. Last but not least, I’ll share the story of the Scion and what the final fix turned out to be!
