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

Connecting terminals 13 (TC) and 4 (CG) of the DLC3 causes the ECU to output the DTCs by blinking the ABS warning light and slip indicator light.

WIRING DIAGRAM

HINT
When the warning lights continue to blink, a ground short in the wiring of terminal 13 (TC) of the DLC3 or an internal ground short in one or more ECUs is suspected.

INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform calibration Programming and Relearning.

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM ABS Warning Light Remains ON

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

2. INSPECT DLC3

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

Standard Voltage:

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

3. INSPECT ECM (DLC3 INPUT)

SST : 09843-18040

(a) Turn the ignition switch off.

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

B -- REPAIR OR REPLACE WIRE HARNESS OR ECM

A -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal

4. CHECK HARNESS AND CONNECTOR (DLC3 - ECM)

(a) Disconnect the A35 ECM 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.

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. INSPECT ECM (DLC3 INPUT)

SST : 09843-18040

(a) Turn the ignition switch off.

(b) Connect the A35 ECM connector.

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

(d) Turn the ignition switch to ON.

(e) Check that the MIL is blinking.

Result

B -- REPAIR OR REPLACE WIRE HARNESS OR ECM

A -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal
