DESCRIPTION If the tire pressure warning ECU and receiver detects any problems, the tire pressure warning light blinks for 1 minute then illuminates, and tire pressure monitoring is disabled at the same time. At this time, the ECU stores a DTC in memory. The tire pressure warning ECU and receiver sends the tire pressure warning light illumination request signal to the main body ECU (multiplex network body ECU) via a direct line. The main body ECU (multiplex network body ECU) then sends the signal to the combination meter assembly via CAN communication. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE:
