BRAKE CONTROL: ANTI-LOCK BRAKE SYSTEM: TS and CG Terminal Circuit

TS and CG Terminal Circuit

DESCRIPTION

In the sensor check mode, a malfunction in the speed sensor that cannot be detected when the vehicle is stopped is detected while driving.
Transition to the sensor check mode can be performed by connecting terminals TS and CG of the DLC3 and turning the ignition switch from OFF to the ON position.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DLC3 (TS VOLTAGE)





(a) Turn the ignition switch to the ON position.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:






NG -- CHECK WIRE HARNESS (DLC3 - BODY GROUND)
OK -- Continue to next step.
2. CHECK WIRE HARNESS (SKID CONTROL ECU - DLC3)





(a) Disconnect the S1 skid control ECU connector.
(b) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE BRAKE ACTUATOR ASSEMBLY
3. CHECK WIRE HARNESS (DLC3 - BODY GROUND)





(a) Measure the resistance of the wire harness side connector.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
4. CHECK WIRE HARNESS (SKID CONTROL ECU - DLC3)





(a) Disconnect the S1 skid control ECU connector.
(b) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE BRAKE ACTUATOR ASSEMBLY
