What are the causes of Buick Regal's tire pressure monitoring system malfunction?

[SanSteven]

In fact, such issues are usually caused by electromagnetic interference. It is estimated that the tire pressure reception frequency of General Motors is close to the frequency of self-installed electronic equipment, leading to this problem. Below is the relevant introduction: 1. Introduction to the tire pressure monitoring system: TPM-IS is a tire pressure detection initialization system specially designed for vehicle manufacturers. It uses radio frequency technology to quickly activate, identify, and locate various TPMS sensors, and writes relevant information into the vehicle's ECU electronic control unit through the OBDII interface, ultimately realizing the initialization of the tire pressure detection system. 2. Structure: TPM-IS consists of a line-side industrial computer, barcode scanner, vehicle positioning and identification device, LF wake-up module, RF receiving module, printing equipment, alarm equipment, etc.
