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 Techstream and note them down before removal.
- It is necessary to perform the initialization Initialization after the registration Registration of the transmitter IDs into the tire pressure warning ECU if the ECU has been replaced.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (DLC3 - TIRE PRESSURE WARNING ECU)




(a) Disconnect the D54 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
