Review on 🔧 KINGBOLEN EL-50448 TPMS Reset Tool: Effortlessly Reset Tire Pressure Monitors in GM Series Vehicles by Jonathan Fernandez

2015 GMC 2500HD Diesel. According to the instructions, the ignition was turned on in the park. The DIC was set to TPMS and tire pressure was displayed. The tick button on the steering wheel was pressed before two beeps indicated entry into learn mode. Numerous attempts have been made without success. The last attempt with the engine running was successful and completed in about a minute. The only difference was that the engine was running.
