TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: TC and CG Terminal Circuit

TC and CG Terminal Circuit

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 IDs stored in the ECU using the intelligent tester and write them down before removal.
- It is necessary to perform initialization Initialization after registration Registration of the transmitter IDs into the tire pressure warning ECU after the ECU and/or valve and transmitter have been replaced.

PROCEDURE

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





(a) Disconnect the T11 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
