TC and CG Terminal Circuit

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for BOSCH Made): 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.

DTCs are indicated by the blinking pattern of the ABS warning light.

WIRING DIAGRAM





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

INSPECTION PROCEDURE

HINT
Check the condition of each related circuit connector before troubleshooting Electronic Circuit Inspection Procedure.

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication DTC is output Vehicle Stability Control System (for BOSCH Made).

Result:





B -- CHECK HARNESS AND CONNECTOR (ECM TO DLC3)

A -- GO TO CAN COMMUNICATION SYSTEM How to Proceed With Troubleshooting

2. CHECK HARNESS AND CONNECTOR (ECM TO DLC3)

(a) Disconnect the ECM connector.





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

Standard resistance:

2GR-FE
2AR-FE










(c) Connect the connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (DLC3 TO CG CIRCUIT)

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





Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CG TERMINAL CIRCUIT)
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (TC TERMINAL CIRCUIT)

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





Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)

OK -- REPLACE BRAKE ACTUATOR ASSEMBLY Removal
