If malfunctions are detected in the system, the tire pressure warning system ECU warns the driver by illuminating the tire pressure warning light after blinking it at 1 Hz intervals for 1 minute, and stores the DTC (Diagnostic Trouble Code) in the memory.
The DTC that are stored by the tire pressure warning system ECU can be accessed by connecting the SST (09843-18040) to the DLC3 terminals TC and CG, and reading the blinking of the tire pressure warning light. They can also be accessed by connecting a hand-held tester. The table below lists the DTC that pertain to this system. For further details, see the 2007 Camry Repair Manual (Pub No. RM0250U).
