Question
How do you resolve “TPMS not communicating with ECU” after battery replacement?
Answer
Reset the ECU’s TPMS memory and relearn all sensors via OBD.
Explain
Battery disconnect erases temporary TPMS data; use CHEPQ tools to force ECU reinitialization. This step is critical for vehicles with “volatile TPMS memory” (e.g., Honda, Nissan).
