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 IDs 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.”

The owner’s manual on the GMC Sierra states, “There are two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. Push and hold trip reset stem to begin the sensor matching process.Push the trip odometer reset stem until Tire Pressure is displayed.Manual relearn procedure, Base level DIC years 2014-2020: Horn chirps 2x DIC displays TIRE LEARNING ACTIVE.

Manual (stationary) relearn, years 2007-2020.2019 models use both 315 MHz and 433 MHz frequencies.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 Sierra, a manual (stationary) or OBD TPMS relearn is recommended to transfer new and/or existing TPMS sensor IDs 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 Sierra is manufactured with a direct TPMS system, which means TPMS sensors are installed in the wheel. Some earlier model vehicles (pre-2007) may require the use of the Tech2 and “Legacy Tech 2” programming option in SPS in order to utilize a slower programming communication speed.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. Reattempt programming using “Replace and Program ECU.” Reestablish and maintain battery power, and then attempt to communicate with the control module using MDI or Tech 2. If communication cannot be reestablished, deplete retained power by disconnecting the negative battery terminal for a minimum of 5 minutes. If communication can be established, reattempt programming using “Replace and Program ECU” as the programming method. This should first be done with GDS2 or Tech 2. Attempt to reestablish communication with the module. Maintain a minimum of 12.5 volts during programming. This error typically stems from a loss of communication between the programming device and the module - which can be caused by either a drop in battery voltage, a delay in communication with the module or a vehicle issue, such as an interruption on the BUS (wiring, connector issue, aftermarket components, etc.).
