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 TC and CG of the DLC3.

The DTCs are displayed by blinking the tire pressure warning light.

INSPECTION PROCEDURE

NOTICE:
* 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.
* If the ECM has been replaced, it is necessary to register the ECU Removal for 2GR-FSE, Removal for 1UR-FSE).

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM AND MULTIPLEX COMMUNICATION SYSTEM

(a) Check if a DTC of CAN communication system and multiplex communication system is output.

Result:





B -- REPAIR CIRCUITS INDICATED BY OUTPUT DTCS
A -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (ECM - DLC3)

(a) Disconnect the A7 ECM connector.





(b) Measure the resistance according to the value(s) in the table below.

Standard resistance (for 2GR-FSE):





Standard resistance (for 1UR-FSE):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT DLC3 (TC VOLTAGE)





(a) Turn the engine switch on (IG).

(b) Measure the voltage according to the value(s) in the table below.

Standard voltage:





NG -- REPLACE ECM
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)

(a) 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 Symptom Related Diagnostic Procedures
