TC and CG Terminal Circuit
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: TC and CG Terminal Circuit
TC and CG Terminal Circuit
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the ECU to display DTCs by blinking the ABS warning light and VSC OFF indicator light.

INSPECTION PROCEDURE
NOTICE:
- When replacing the VSC actuator assembly, perform initialization of linear solenoid valve calibration Programming and Relearning.
- for 1GR-FE:
If the ECM has been replaced, it is necessary to register the Vehicle Identification Number (VIN) Programming and Relearning.
- for 2UZ-FE:
If the ECM has been replaced, it is necessary to register the Vehicle Identification Number (VIN) Programming and Relearning.
- for 3UR-FE:
If the ECM has been replaced, it is necessary to register the Vehicle Identification Number (VIN) Programming and Relearning.
- for 3UR-FBE:
If the ECM has been replaced, it is necessary to register the Vehicle Identification Number (VIN) Programming and Relearning.
PROCEDURE
1. INSPECT DLC3 (TC AND CG TERMINAL)
(a) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- CHECK HARNESS AND CONNECTOR (DLC3 - ECM)
OK -- Continue to next step.
2. CHECK CAN COMMUNICATION SYSTEM
(a) Check if a CAN communication DTC is output How to Proceed With Troubleshooting.
Result
B -- GO TO CAN COMMUNICATION SYSTEM
A -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (DLC3 - ECM)
(a) Disconnect the A24 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 -- 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 -- Continue to next step.
5. CHECK ECM (DLC3 INPUT)
(a) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
SST: 09843-18040
(b) Check if the ABS warning light is blinking.
Result
E -- REPLACE ECM
D -- REPLACE ECM
C -- REPLACE ECM
B -- REPLACE ECM
A -- REPLACE VSC ACTUATOR ASSEMBLY
