VEHICLE STABILITY CONTROL SYSTEM TS and CG Terminal Circuit

DESCRIPTION

In Test Mode (Signal Check), a malfunction in the speed sensor that cannot be detected when the vehicle is stopped can be 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 ON.

INSPECTION PROCEDURE

Note

When replacing the skid control ECU (brake actuator assembly), perform system variant learning and acceleration sensor zero point calibration Click here.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TS of DLC3 - BRAKE ACTUATOR ASSEMBLY)


    1. Disconnect the A78 (for CVT) or A79 (except CVT) skid control ECU (brake actuator assembly) connector.

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

      Standard Resistance (for CVT)
      Tester Connection Condition Specified Condition
      H16-12 (TS) - A78-27 (TS) Always Below 1 Ω
      H16-12 (TS) or A78-27 (TS) - Body ground Always 10 kΩ or higher
      Standard Resistance (except CVT)
      Tester Connection Condition Specified Condition
      H16-12 (TS) - A79-3 (TS) Always Below 1 Ω
      H16-12 (TS) or A79-3 (TS) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
