TC and CG Terminal Circuit

BRAKE CONTROL: ANTI-LOCK BRAKE 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.
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 ABS (Antilock Brake System).
Result:






B -- CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
A -- GO TO CAN COMMUNICATION SYSTEM
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





2AZ-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 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. REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)




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






NG -- CHECK HARNESS AND CONNECTOR (TC TERMINAL CIRCUIT)
OK -- REPLACE BRAKE ACTUATOR ASSEMBLY
