Question
How does TPMS interact with the vehicle’s ECU?
Answer
Sensors transmit pressure/temperature data to the ECU, which analyzes it and triggers alerts if values are out of range.
Explain
The ECU polls sensors every 10-30 seconds (varies by speed) and integrates TPMS data with other systems (e.g., disabling cruise control if pressure is critically low). CHEPQ scanners read ECU TPMS logs to review historical data (e.g., “Pressure dropped to 18 PSI at 2:15 PM”).
