Question
Why do some TPMS warnings show the wrong tire position?
Answer
The ECU’s ID-to-corner mapping is incorrect (e.g., after rotation without relearn).
Explain
The ECU thinks Sensor A is left-front but it’s now right-rear. Use CHEPQ tools to reassign IDs to correct positions, fixing the warning.
