WARNING: This page is about a different variant/trim than selected.
Various TPMS functions rely on a speed signal that must be accurate to the actual vehicle speed. Three speed signals (ABS1 FR wheel, EMS1 speed signal, TCS5 FR wheel) are compared for accuracy. These three speed signals must be identical. If not, a DTC will be set and the TPMS warning indicator will illuminate.
