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 ignition switch to ON.

(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

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Select CAN Bus Check from the System Selection Menu screen and follow the prompts on the screen to inspect the CAN bus Diagnosis System.

OK:

CAN Bus Check indicates no malfunctions in CAN communication.

3. CHECK DTC (CAN COMMUNICATION SYSTEM)

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Check for DTCs Diagnosis System.

4. CHECK HARNESS AND CONNECTOR (ECM - DLC3)

(a) Turn the ignition switch off.

(b) Disconnect the F50 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 malfunction indicator lamp is blinking.
