2007 Tundra Tire Pressure Warning Light Flashing

    Some 2007 model year Tundra vehicle customers may complain of the Tire Pressure Warning System light intermittently flashing or turning “ON” with the following DTCs stored in the TPMS ECU:

    C2121 — Transmitter ID1
    C2122 — Transmitter ID2
    C2123 — Transmitter ID3
    C2124 — Transmitter ID4

    The TPMS ECU Assemblies have been modified to correct this condition. The old part number (89769--0C010) is replaced with the updated part number (89769--0C011). The TPMS ECU is located behind the glove box, next to the blower motor. See TSB SU005-07
