TC and CG Terminal Circuit

DESCRIPTION

Connecting terminals TC and CG of the DLC3 causes the ECU to display 2-digit DTCs by blinking the ABS warning light and SLIP indicator light.

INSPECTION PROCEDURE
NOTE: When replacing the master cylinder solenoid, perform the zero point calibration Programming and Relearning.

PROCEDURE

1. INSPECT DLC3 TERMINAL VOLTAGE (TC)




(a) Turn the ignition switch to ON.
(b) Measure the voltage.
Standard voltage:






NG -- CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)
OK -- Continue to next step.
2. CHECK CAN COMMUNICATION SYSTEM
(a) Check whether CAN communication DTC(s) is output Diagnosis System.
Result:






B -- REPAIR CAN COMMUNICATION SYSTEM
A -- REPLACE MASTER CYLINDER SOLENOID
3. CHECK HARNESS AND CONNECTOR (DLC3 - BODY GROUND)




(a) Measure the resistance.
Standard resistance:






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




(a) Disconnect the ECM connector.
(b) Measure the resistance.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. INSPECT ECM (DLC3 INPUT)




(a) Connect terminals TC and CG of the DLC3.
(b) Turn the ignition switch to ON.
(c) Check that the MIL is blinking.
OK:
MIL is blinking.
NG -- REPLACE ECM
OK -- REPLACE MASTER CYLINDER SOLENOID
