#Gmc acadia software update manual#

From the second half of the production year, the GMC Acadia is manufactured with 433 MHz TPMS sensors. The GMC Acadia was manufactured with 315 MHz TPMS sensors from 2007 through the first half of the production year. It is also recommended to do a TPMS reset after a wheel or sensor replacement. When tires are rotated, GMC recommends resetting the TPMS system by performing a TPMS relearn to transfer the new location of the TPMS sensors to the vehicle’s ECU. 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. GMC recommends rotating tires every 7,500 miles (12 000 kilometers). Lowering the driver’s side window may help complete the process for larger GMC vehicles It takes two minutes or less to perform an OBD relearn procedure on a GMC Acadia, and requires just one relearn procedure to memorize for various vehicle Makes. 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. The solution? For most GMC vehicles, the bonus OBD relearn procedure is available for the ATEQ VT56, thanks to patented Sync-ID technology. 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. If it takes longer, the matching process stops and must be restarted.”

Type of TPMS tool required for TPMS reset

Bonus OBD relearn procedure coverage as an option on the VT56, requires OBD module.

433 MHz for years 2016-2020 (second half of production year).

315 MHz for years 2007-2016 (first half of production year).

All OE and aftermarket TPMS part numbers and service kit replacement options for the GMC Acadia can be found in the VT56 in “Service TPMS”.

Direct TPMS, sensors are installed in the wheel.

When a sensor is replaced in one or more tires, one or more wheels are replaced or tires are rotated in a GMC Acadia, a manual (stationary) or OBD TPMS relearn is recommended to transfer new and/or existing TPMS sensor ID’s 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). If one or more tires indicate low tire pressure, the TPMS sensors will transfer the information to the vehicle’s ECU. The GMC Acadia is manufactured with a direct TPMS system, which means TPMS sensors are installed in the wheel.

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.
