TPMS diagnostic information – Chevy Trax, 2013-2019
After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems.
The Chevy Trax is manufactured with a direct TPMS system, which means TPMS sensors are installed in the wheel. If one or more tires indicate low tire pressure, the TPMS sensors will transfer the information to the vehicle’s ECU. An indicator light (low-line TPMS system) or each tire pressure will show on the dash (high-line TPMS system).
When a sensor is replaced in one or more tires, one or more wheels are replaced or tires are rotated in a Chevy Trax, a manual (stationary) or OBD TPMS relearn is recommended to transfer new and/or existing TPMS sensor ID’s to the vehicle’s ECU.
The owner’s manual on the Chevy Trax states, “There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted.”
If the horn chirps twice before all steps have been performed or sensors have been activated, the relearn procedure most likely has failed and the ID’s did not transfer correctly, which means the procedure has to start over again.
The solution? For most Chevy vehicles, the bonus OBD relearn procedure is available for the ATEQ VT56 and VT46 brands, thanks to patented Sync-ID technology. This advanced feature allows the user to perform an OBD relearn to turn the light off, with minimal to no driving time required to turn the light off, saving the technician time and the customer labor costs. It takes two minutes or less to perform an OBD relearn procedure on a Chevy Trax, and requires just one relearn procedure to memorize for various vehicle Makes.

Chevy recommends rotating tires every 7,500 miles (12 000 kilometers). Tire rotation helps with even wear for all tires and is important for balanced handling on the road, which can extend the life of tires and save money in the long-run. When tires are rotated, Chevy recommends resetting the TPMS system by performing a TPMS relearn to transfer the new location of the TPMS sensors to the vehicle’s ECU.
It is also recommended to do a TPMS reset after a wheel or sensor replacement.
Use the VT56 to retrieve Chevy TPMS DTC codes by selecting the “Service” icon. After selecting the Make, Model, and Year, select the DTC code icon. Use the OBDII module to retrieve the Chevy DTC TPMS information to diagnose and service the TPMS issues determined.
