DESCRIPTION
DTC output mode is set by connecting terminals 13 (TC) and 4 (CG) of the DLC3. The DTCs are indicated by blinks of the tire pressure warning light.
WIRING DIAGRAM
HINT: When each warning light blinks continuously, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in an ECU connected to this circuit may have occurred.
INSPECTION PROCEDURE
NOTICE: When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the intelligent tester and write them down before removal.
It is necessary to register an ID code after replacing the tire pressure warning valve and transmitter and/or the tire pressure warning ECU (See page TW-20).
1 CHECK HARNESS AND CONNECTOR (DLC3 - TIRE PRESSURE WARNING ECU)
(a) Disconnect the T15 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
