TC and CG Terminal Circuit

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL 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.

WIRING DIAGRAM





HINT
When each warning light continues blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in each ECU is suspected.

INSPECTION PROCEDURE

NOTICE:
When replacing the master cylinder solenoid, perform calibration Programming and Relearning.

PROCEDURE

1. INSPECT DLC3

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

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





Standard Voltage:

NG -- CHECK HARNESS AND CONNECTOR (ECM - DLC3)
OK -- Continue to next step.

2. CHECK CAN COMMUNICATION LINE ABS Warning Light Remains ON

NG -- GO TO CAN COMMUNICATION SYSTEM (HOW TO PROCEED WITH TROUBLESHOOTING) How to Proceed With Troubleshooting
OK -- Continue to next step.

3. CHECK DTC (CAN COMMUNICATION SYSTEM)

(a) Turn the engine switch off.

(b) Connect the Techstream to the DLC3.

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

(d) Turn the Techstream on.

(e) Check for DTCs Diagnosis System.

Result





B -- GO TO CAN COMMUNICATION SYSTEM (HOW TO PROCEED WITH TROUBLESHOOTING) How to Proceed With Troubleshooting
A -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (ECM - DLC3)

(a) Turn the engine switch off.

(b) Disconnect the G45 ECM connector.

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

Standard Resistance:





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

5. 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 -- Continue to next step.

6. CHECK ECM (DLC3 INPUT)





(a) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.

SST : 09843-18040

(b) Check that the MIL is blinking.

Result





B -- REPAIR OR REPLACE WIRE HARNESS OR ECM
A -- Continue to next step.

7. CHECK DTC (CAN COMMUNICATION SYSTEM)

(a) Turn the engine switch off.

(b) Connect the Techstream to the DLC3.

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

(d) Turn the Techstream on.

(e) Check for DTCs Diagnosis System.

Result





B -- GO TO CAN COMMUNICATION SYSTEM (HOW TO PROCEED WITH TROUBLESHOOTING) How to Proceed With Troubleshooting

A -- REPLACE MASTER CYLINDER SOLENOID Disassembly
