BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: TS and CG Terminal Circuit

TS and CG Terminal Circuit

DESCRIPTION

In the sensor check mode, a malfunction of 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

NOTE: When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (Programming and Relearning).

PROCEDURE

1. INSPECT DLC3

(a) Turn the ignition switch to the ON position.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:

NG -- CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (TS of DLC3 - SKID CONTROL ECU)

(a) Disconnect the skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
3. CHECK HARNESS AND CONNECTOR (CG of 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.
4. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - TS of DLC3)

(a) Disconnect the skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
