2007 Tundra Tire Pressure Warning Light Flashing


Staff member
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
